20W PCB mount AC/DC converters for harsh industrial environments

October 10, 2016 // By Graham Prophet
Recom (Gmunden, Austria) has designed its RAC20-N as an AC/DC converter in modular design format for mounting onto PCBs. The 2 x 1 inch casing is intended for use in harsh industrial environments.

The AC/DC converter is equipped with a universal input for 90–264V AC, and is pin-compatible with RAC05-SC, RAC06-SC, RAC10-SC and RAC20-SB models for an easy power upgrade or reduced-cost version without other alterations to the PCB. This 20W AC/DC power supply in protection class II has 3.3, 5, 12, 15 and 24V DC outputs, and operates with efficiency of up to 83%. The low open-circuit power consumption of less than 0.25W complies with the ErP ecodesign directive, and the module’s robust construction is suitable for use at over temperatures from -40 to +70°C. Press-insert nuts ensure secure and vibration-free installation to withstand hard impacts and vibration in harsh operating environments. The module is intended for industrial applications as well as testing and measuring systems as well as portable units. Short-circuit, overload and overvoltage protection as well as electromagnetic compatibility according to EN55022 Class B are among its features. RAC20-N is certified according to IEC, UL and EN60950-1 and bears a CE mark, and comes with a three-year guarantee from Recom.
