DC/DC Converters - Schaefer Inc.


Schaefer announces the PRC-120 Series of DC/DC converters that provide 120W of power in a compact, chassis mount package. The PRC-120 Series has versions that meet industrial (EN60950) or rail (EN50155) standards. Standard nominal input voltages are 24VDC, 48VDC, 72VDC, and 110VDC. The PRC-120 Series provides highly efficient (up to 92%) conversion to adjustable 5VDC, 12VDC, 24VDC and 48VDC outputs that are tightly regulated to 0.2% or better. 

All models in the PRC-120 Series boast comprehensive protection circuitry against short circuit/overload, input reverse polarity, input under voltage and undercurrent. Remote sense, remote inhibit, and LED indicators are part of the standard design.  A wide operating temperature of up to -25C to +70C allows for installations in extreme conditions and meets EN50155 Class 3. Emissions compliance to EN61000-6-3 and EN60121-3-2 meets both industrial and rail standards and minimizes interference to other sensitive equipment.   The compact size of the PRC-120 Series measures 6.30” x 3.94” x 1.38”.  In addition to chassis mounting, an optional DIN rail clip, mounting base, or Eurocard front panel are available. Schaefer’s full family of DC/DC converters also includes other modules starting at 45W of power and increases in ratings up to high power (30kW) designs.
