Programmable HVDC Power Supply Manufacturers & Exporters

POWERTRON manufactures the complete range of programmable HVDC power supply systems in India, delivering regulated high voltage DC output from 500W to 8kW as standard and up to 50kW on customised builds. Output is continuously adjustable from +1000V to +50kV, with matched negative-polarity models from −1000V to −50kV, so a single design platform covers laboratory, production-test and plant-level requirements. Every unit combines digital set-point control, ripple held to 0.05% FS, hardware soft-start with no startup overshoot, and a complete protection stack — making it suited to insulation and withstand testing, capacitor charging, X-ray and electron-beam systems, semiconductor process tools, electrostatic applications and EV component validation. Designed, wound, assembled and load-tested in-house at the company’s Wagle Estate facility in Thane, Maharashtra, POWERTRON HVDC supplies serve customers across India and export markets including the Middle East and Southeast Asia.

CV-CC Controller Battery Charger

Programmable HVDC Power Supply

FEATURES :

  • Wide output coverage in one platform — 500W to 8kW standard with customised builds to 50kW, and voltage from +1000V to +50kV, so a single vendor and a single control philosophy covers every bench and plant requirement on site.
  • Positive and negative polarity models — matched N-suffix variants from −1000V to −50kV remove the need to source a second supply from a different manufacturer when the application reverses polarity.
  • Low ripple, high stability — ripple held to ≤0.05% FS on lower-voltage models and ≤0.1% FS across the range, giving clean DC for detectors, imaging chains and precision measurement where noise corrupts the result.
  • No overshoot at startup — soft-start implemented in hardware rather than firmware alone, so a fragile DUT or a capacitor bank never sees a transient while the control loop is still settling.
  • Software-adjustable voltage rise time — ramp rates can be matched to the IEC and IS withstand procedures your test standard specifies, instead of forcing the procedure to fit the equipment.
  • List Mode and Auto Run — a complete multi-step conditioning or withstand routine runs from a single trigger, and repeats automatically at power-up for unattended burn-in and overnight soak testing.
  • Preset with output open-circuit — voltage and current can be dialled in and verified before high voltage is ever applied to the load, removing the most common operator error in HV testing.
  • Multi-layer protection — OVP, OTP, AC-fail detection and programmable current limit act together as both a compliance setting and an arc-energy limiter.
  • Standard Modbus-RTU over RS232 and RS485 — the supply drops into an existing PLC, SCADA or LabVIEW rig without a custom driver being written.
  • Optional analog and LAN interfaces — 0–5V, 0–10V or 4–20mA command and feedback for legacy control loops, or LAN for Ethernet-based ATE and remote monitoring.

How a Programmable HVDC Power Supply Works

A programmable HVDC power supply converts incoming AC mains into a precisely regulated high voltage DC output under closed-loop digital control. The incoming supply is first rectified and filtered to an intermediate DC bus. That bus feeds a high-frequency switching inverter, which drives a high voltage step-up transformer at tens of kilohertz rather than at mains frequency. Switching at high frequency is what allows a 50kV supply to occupy a fraction of the volume and weight a conventional mains-frequency transformer-rectifier set would need for the same rating.

The transformer secondary feeds a high voltage rectifier and multiplier stage, typically a Cockcroft–Walton or cascaded diode-capacitor arrangement for the higher kV classes, followed by an HV filter network that suppresses ripple. Output voltage and current are continuously sampled through a precision high voltage divider and a current-sense element, and both signals are returned to the digital controller.

The controller compares those readings against the programmed set point and adjusts the inverter duty cycle accordingly. Because regulation is closed-loop and digital, the supply automatically operates in constant-voltage mode until the load draws the programmed current limit, at which point it crosses over into constant-current mode and holds there — the behaviour that makes these units safe on capacitive and arc-prone loads.

Protection is layered on top of the same control loop. Over-voltage, over-temperature and AC-fail conditions are detected in firmware and acted on within the switching period, while soft-start is implemented in hardware so the output rises in a controlled ramp regardless of what the firmware is doing at power-on. High voltage insulation is achieved by air spacing below 20kV and by encapsulation or oil immersion above it.

Applications of High Voltage DC Power Supplies by Industry

Selecting an HVDC power supply starts with the load, not the label. Capacitive loads need controlled rise time and current limiting; resistive insulation loads need voltage stability held precisely at the withstand level; beam and emission loads need very low ripple above all else; arc-prone process loads need fast current limiting and clean recovery. The mapping below is a starting point — POWERTRON engineers size the final unit against the actual load curve.

Industry Application Load Character Recommended Configuration
Power Utilities & Cable DC withstand and insulation resistance testing on cables, bushings, transformers Resistive with leakage 3kV–12kV, 600W–1200W, positive polarity, adjustable ramp

Programmable HVDC Power Supply vs Conventional High Voltage Sources

Many Indian plants still run legacy variac-and-rectifier HV sets or unregulated transformer stacks. The comparison below is the single highest snippet-value block on the page.

Criteria POWERTRON Programmable HVDC Conventional / Analog HV Source
Set-point accuracy Digital entry, repeatable to 1 V resolution Manual dial, operator-dependent and unrepeatable
Ripple and stability ≤0.05–0.1% FS, regulated continuously High ripple, drifts with mains and load variation
Regulation mode Automatic CV/CC crossover at the programmed limit No true current limit; fuse acts as the only ceiling
Automation RS232/RS485 Modbus-RTU, LAN, List Mode sequencing Little or no remote control capability
Protection OVP, OTP, ACF, programmable current limit Fuse and MCB only
Test traceability Digital readback of V and I for logging and reports Manual meter reading, no digital record
Footprint and efficiency Compact HF switch-mode topology, high efficiency Bulky mains-frequency magnetics, higher losses and heat
Polarity change Negative-output models available across the range Usually requires a separate unit or rewiring
Startup behaviour Hardware soft-start, zero overshoot Uncontrolled inrush, overshoot risk to the load

Selection Checklist

  • Peak output voltage required, plus headroom — specify at least 20% above the highest test voltage so the unit is never run at the top of its range, where regulation and life are both worst.
  • Actual current draw, not just power — a 10kV/60mA unit and a 1kV/600mA unit are both 600W and behave nothing alike. Give the real load current, including leakage and any inrush.
  • Polarity — positive, negative, or both. Negative-output models exist across the POWERTRON range, but genuine polarity reversal within one chassis is a custom bipolar build and must be flagged at enquiry.
  • Load type — capacitive, resistive, arcing or beam. This decides the ramp strategy, the current-limit behaviour and whether arc-recovery logic is needed.
  • Ripple and stability class — imaging, detection and metrology applications should specify the ≤0.05% FS grade explicitly rather than accepting the range default.
  • Control interface — Modbus-RTU over RS485, analog 4–20mA, or LAN. Deciding before order means the unit ships configured rather than being reworked on site.
  • Duty cycle and ambient — continuous, intermittent or pulsed, and the actual panel or room temperature. Indian summer ambients in unconditioned test halls materially affect derating.
  • Mounting format and interlock requirement — bench, 19-inch rack or floor-standing, and whether cabinet-door interlocks must be tied into the output enable.

Custom High Voltage DC Power Supply Manufacturing

Beyond the standard catalogue, POWERTRON builds custom high voltage DC power supplies to drawing. Non-standard voltage and current combinations are routine, as are extended power ratings up to 50kW, bipolar output where the application genuinely reverses polarity, and encapsulated or oil-insulated HV tanks for the higher kV classes where air insulation is no longer viable. Enclosure format follows the installation — bench, 19-inch rack, or floor-standing cabinet with integrated interlocks and HV-rated terminations.

Firmware is equally configurable: custom List Mode profiles, application-specific protection thresholds, extended Modbus register maps and non-standard analog scaling can all be factory-set. The process is straightforward — share the load characteristics, duty cycle, interface requirement and mechanical constraint, and the application engineering team returns a proposed configuration with an indicative timeline. Because design, magnetics, assembly and full-load testing all happen under one roof in Thane, custom builds do not carry the lead-time penalty typical of imported equivalents.

Frequently Asked Questions — Programmable HVDC Power Supply

What is the maximum output voltage of a POWERTRON programmable HVDC power supply? +

Standard catalogue models cover +1000V to +50kV, with negative-polarity variants from −1000V to −50kV. Rated output power runs from 500W to 8kW as standard and is customised up to 50kW for industrial and research installations. The full model matrices on this page list the exact voltage and current pairing available in each power class.

Can one unit provide both positive and negative high voltage output? +

Standard models are supplied as either positive (P suffix) or negative (N suffix) polarity. Applications that genuinely require polarity reversal within a single chassis — certain electrostatic precipitator, MEMS and materials-test setups — are handled as a customised bipolar build. Flag the switching requirement at enquiry stage so the correct topology is quoted.

How is the power supply controlled remotely? +

RS232 and RS485 with a Modbus-RTU command set are standard on every unit, so the supply integrates directly with PLCs, SCADA systems, LabVIEW and other test-automation software without a custom driver. Optional 0–5V, 0–10V and 4–20mA analog control and feedback, and a LAN interface, are available and are factory-configured when specified at order.

What ripple and stability can I expect? +

Voltage ripple is ≤0.05% FS on the lower-voltage models and ≤0.1% FS across the wider range, with regulation maintained through both mains and load variation. Applications involving imaging, radiation detection or precision metrology should specify the ≤0.05% FS class explicitly at enquiry rather than accepting the range default.

Is a programmable HVDC power supply suitable for capacitor charging? +

Yes — capacitor charging is one of the primary applications. Software-adjustable voltage rise time, hardware soft-start with no overshoot, and a programmable current limit together allow the charge profile to be shaped so that neither the capacitor bank nor the supply is stressed. Provide the bank capacitance and target charge time when enquiring.

What protections are built in? +

Over-voltage protection with a programmable trip point, over-temperature protection on the power stage, AC-fail detection that brings the output down cleanly on mains loss, and a programmable current limit that acts as both a compliance setting and an arc-energy limiter. Interlock provision, HV-rated terminations and defined creepage and clearance support safe cabinet installation.

Can POWERTRON supply a non-standard voltage and current rating? +

Yes. Custom HVDC power supplies are built to specification, including non-catalogue voltage and current combinations, extended power ratings to 50kW, encapsulated or oil-insulated HV assemblies, bipolar output and specific enclosure formats. Provide load type, duty cycle, ambient conditions and interface requirement for a firm proposal.

What is the difference between List Mode and Auto Run? +

List Mode stores a multi-step sequence of voltage, current and dwell settings that executes from a single trigger — useful for standard withstand and conditioning routines. Auto Run executes that stored sequence automatically whenever the unit is powered on, which suits burn-in cells and unattended overnight soak testing.

Where is POWERTRON located and do you export? +

Manufacturing is at Wagle Estate MIDC, Thane West 400604, Maharashtra, India. Domestic sales and service offices operate in Delhi, Pune, Hyderabad, Bangalore and Tamil Nadu, with international offices in Dubai, Singapore and Malaysia. Export enquiries are welcome and full documentation is supplied.

What information should I send when requesting a quotation? +

Maximum output voltage and current, polarity, load type, required ripple class, control interface, duty cycle, ambient temperature and mounting format. With those eight inputs the correct model can be identified from the tables on this page or quoted as a custom build.
