AC DC Converter (Din Rail SMPS) Manufacturers & Exporters
Powertron's DIN Rail AC to DC Converter is a compact SMPS built to snap directly onto standard DIN rail inside control panels and switchgear cabinets, delivering regulated 12V, 24V or 48V DC at up to 20A. With universal AC input, full protection coverage and a 100% burn-load burn-in test on every unit, it's built for panel builders and OEMs who need a dependable, space-saving DC source rather than a bench power supply retrofitted into a cabinet. This page covers features, specification, model options and how to select the right current rating.
Technical Specifications — DIN Rail AC to DC Converter
| Parameter | Specification | What It Means For You |
|---|---|---|
| Output Voltage | 12V / 24V / 48V DC | Covers the three most common control and automation voltage standards from one product family. |
| Rated Current | 2.5A / 5A / 10A / 20A, or custom | Matches the unit to your actual panel load instead of over-specifying. |
| Input | Universal AC input range | One SKU works across varying incoming supply without a regional input variant. |
| Protection | Short circuit / overvoltage / overload / over-temperature | Four fault modes are covered on the converter itself, reducing what needs to be protected externally in the panel. |
| Cooling | Free-air convection, fanless | No fan bearing to wear out and no acoustic noise inside an enclosed cabinet. |
| Mounting | Standard 35mm DIN rail | Installs and removes without brackets, cutting panel-build time versus chassis-mount alternatives. |
| Testing | 100% full-load burn-in before dispatch | Every unit is proven at rated current before it ships, not sample-tested. |

| PLC, relay logic, standard automation panel | 24V, 5A – 10A |
| Larger control panel / multiple sub-loads | 24V/48V, 10A – 20A or custom |
How It Works
The DIN Rail AC to DC Converter is a switch-mode power supply (SMPS) housed in a slim, DIN-rail-mountable enclosure. Incoming AC across a universal input range is switched at high frequency, rectified and filtered to produce regulated 12V, 24V or 48V DC, with the switching architecture giving significantly better efficiency and a smaller footprint than an equivalent linear supply.
Because the unit is fanless and cooled by free-air convection, it has no moving parts inside the enclosure — a meaningful reliability advantage in dusty or vibration-exposed panel environments where a fan bearing would be the first thing to fail. The protection stage continuously monitors output current and voltage plus internal temperature, shutting down cleanly on short circuit, overload, overvoltage or over-temperature before a fault can propagate to the PLC, relays or sensors it's feeding. The LED indicator gives commissioning and maintenance staff an immediate visual check of power status without opening a multimeter on the terminals.
Applications by Industry
| Industry | Application | Load / Duty Character | Recommended Configuration |
|---|---|---|---|
| Switchgear & Control Panels | Primary 24VDC logic supply | Continuous | 24V, 5–10A DIN rail |
| Industrial Automation | PLC, sensor and actuator power | Continuous | 24V, sized to I/O count |
| Telecom & Data Centre | Auxiliary panel power | Continuous | 24V/48V, 5–10A |
| Railway / Metro | Onboard control panel supply | Continuous, vibration-exposed | 24V/48V, ruggedised mounting |
| Oil & Gas Refinery | Instrumentation and control power | Continuous, harsh environment | 24V, protected/enclosed |
| Power Transmission | Substation control panel supply | Continuous, mission-critical | 24V/48V, 10–20A |
DIN Rail SMPS vs. Chassis-Mount / Linear Power Supply
| Criteria | DIN Rail SMPS | Chassis-Mount Linear Supply |
|---|---|---|
| Panel space | Compact, mounts directly on rail | Typically larger footprint, needs brackets |
| Installation time | Snaps onto standard 35mm rail | Requires mounting hardware and wiring clearance |
| Efficiency | Higher — switch-mode design | Lower — resistive linear regulation |
| Weight | Lighter | Heavier, larger transformer core |
| Cooling | Fanless, convection-cooled | Often relies on heatsink mass or forced air |
| Protection coverage | SC/OV/OL/OT built in | Varies, often needs external protection devices |
| Best fit | Modern control panels, standardised builds | Legacy retrofits, specific linear-supply requirements |
Manufacturing & Quality
Every DIN Rail AC to DC Converter is built at Powertron India's own manufacturing facility in Wagle Estate, MIDC, Thane (Maharashtra), where design, winding, assembly, and testing are carried out in-house rather than outsourced. Units go through a documented quality process before dispatch, and Powertron holds ISO, CE, BIS, and GeM empanelment credentials, with manufacturing recognised under the Make in India and MSME programmes. Beyond Thane, Powertron supports customers through sales offices in Delhi, Pune, Hyderabad, Bengaluru and Tamil Nadu, and serves export markets through international sales offices in Dubai, Singapore and Malaysia. Post-installation, the same team that engineers the unit is available for commissioning support, spares, and after-sales service, so buyers are not left dealing with a reseller once the order ships.
FAQ
12V, 24V and 48V DC as standard, with current ratings from 2.5A to 20A.
Yes, custom current ratings above the standard range are available — share your load requirement with sales.
Yes, cooling is by free-air convection with no fan, which removes a common point of failure in panel environments.
Short circuit, overvoltage, overload and over-temperature protection are all standard.
Yes, each converter undergoes a 100% full-load burn-in test at rated current before dispatch.
Yes, it's designed for standard 35mm DIN rail, common across control panel and switchgear enclosures.
Yes, this is a common use case; confirm your specific vibration and temperature requirement when requesting a quotation.
