PSU modules maintain reliability in sub-zero conditions

July 30, 2015 // By Graham Prophet
Recom’s range of low-power modules with rated outputs of 2 or 3W features is extended operating temperature range. RAC02-SE/277 and RAC03-SE/277 modules can now be used in areas where temperatures drop as low as -40°C. The 2W module is now also available with wire connections.

With a height of 18mm, the modules are compact, accommodate a wide input power range of 85-305 VAC (120-430 VDC) and are available with output voltages of 3.3, 5, 12 and 24 VDC. When idle, the modules consume maximum 40 mW and are therefore suitable for the supply of sensors and standby equipment. The insulation strength between the input and the output is 3 kVAC/min. he modules are available as DIP units with standard pinout or as wired units.

Integrated input filters enable conformance to the requirements of EN55022 Class B. They can be operated without the need for additional external components and are short-circuit-proof with automatic restart after fault elimination. The modules are certified according to IEC/EN/UL 60950 and come with a 3-year warranty.
