AC/DC DIN Rail Power Supplies and Accessories

With versions rated at 120W, 240W and 480W, the RACPRO1-S universal single-phase DIN rail AC/DC power supplies are just 28mm, 39mm and 52mm wide respectively.

Adjustable output voltages are available at 12V, 24V and 48V for the 120W and 240W versions, and 24V and 48V for the 480W version. All parts support 150% power for 5s to handle surge loads and feature high return voltage immunity. Full power can be delivered up to +60°C for all parts under convection-only cooling, while higher temperatures can be withstood with derating.

Reliability and lifetime figures are high, supported by impressive efficiency of up to 95%.

The push-in terminals feature a unique ergonomic design and a 25° angle for easy, tool-free operation. These maintenance-free terminals, along with the thoughtfully designed DIN rail mounting clips, allow for quick installation and removal also without the need for tools.

With surge immunity up to 4kV at the input and reverse voltage protection over 35V at the output, these devices are suited for demanding environments. Their extended temperature range of -40°C to +70°C makes them ideal for harsh industrial settings and outdoor applications, especially in renewable energy.

The RACPRO1-4SP series are 4-channel electronic fuse (e-Fuse) load switches designed to provide independent overcurrent protection for each channel. They feature real-time current monitoring and LED status indicators to simplify diagnostics. Each channel operates independently, ensuring system reliability even when faults occur. The design includes sequential power-up to limit inrush current and reverse-sequence shutdown to prioritize essential loads. Adjustable overload modes allow flexible system configuration.

These e-Fuses support 5A or 10A per channel, with a 150% power boost for up to 5s to handle temporary load surges. For short-duration overcurrent events, the device can sustain more than 150% overload for up to 120ms, reducing unnecessary tripping.

Built to LPS installation standards, they offer high reliability with a >80,000h lifetime expectancy at 40°C. Installation is streamlined with tool-free push-in terminals and paired input/output connectors, making wiring and daisy-chaining across multiple modules quick and efficient.

The RACPRO1-RD40 comprises a pair of MOSFETs configured as high-efficiency gating diodes, allowing RECOM DIN rail AC/DCs to be connected in n+1 redundancy arrangements for critical applications where power must be maintained even if one AC/DC goes offline. The module accepts DC inputs up to 56V and can supply an output of up to 40A (60A/5s) over an ambient temperature range of -40°C to +70°C with convection cooling. Maximum voltage drop is 140mV, and the part is certified to IEC/EN/UL/CSA 62368-1 for safety. EN 61000-6-4 Class B emissions and EN 61000-6-2 immunity EMC standards are met. High reliability and long lifetime of over 268,000h at 40°C make the redundancy module suitable for harsh industrial environments.

The module is just 43mm wide, features tool-less mounting, and uses push-in electrical connections angled at 25° for easy system integration.

The new ultra-slim REFIN range of flat-panel DIN rail AC/DC power supplies offers the highest power density of its type on the market and is designed in the industry-standard ‘step-shape’ format. Models are rated at 18W in 1U width, 30W and 60W in 2U width, and a 2U 90W version that provides 150% boost power for 4.5s and can be paralleled for 160W in 4U width. All versions feature universal single-phase AC or high-voltage DC inputs.

Efficiency reaches up to 93.6% , and the series is certified to comprehensive safety and EMC standards. Inputs meet over-voltage category III, supporting operation up to 3000m altitude (90W version: OVCII up to 5000m). Available output voltages range from 5V to 48VDC, rated as LPS/NEC Class 2-limited.

Mounting is tool-free, with optional integrated wings for direct flat-panel installation. Electrical connections are push-in for quick and secure wiring.

The cost-effective REDIIN series AC/DC DIN rail power supplies from RECOM support a 90-264VAC input range with power ratings of 120W, 240W, and 480W, housed in compact 30mm, 40mm, and 56mm widths, respectively. They offer single outputs of 24V and 48VDC, with the 120W variant also available in 12VDC, all adjustable from the module’s front panel.

These power supplies include comprehensive protection and are certified to IEC/EN/UL/CSA 62368-1 and 61010-1 safety standards, while also meeting EMC requirements EN 55032/35 and EN 61204-3, including EN 61000-6-4 Class B emissions for heavy industrial environments. They operate within a -30°C to +50°C range, with functionality up to +70°C under derating and startup capability at -40°C.
