120W DC/DC Converters from Schaefer
120W DC/DC converters.
Hopkinton, MA — Schaefer has introduced the PRC-120 Series of DC/DC converters that provide 120W of power in a compact, chassis-mount package. The converters have versions that meet industrial (EN60950) or rail (EN50155) standards.

Standard nominal input voltages are 24VDC, 48VDC, 72VDC, and 110VDC. The converters provide highly efficient (up to 92 percent) conversion to adjustable 5VDC, 12VDC, 24VDC and 48VDC outputs that are tightly regulated to 0.2 percent or better.

All models have 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 -25 to +70°C 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 converters are compact in size, measuring 6.30 x 3.94 x 1.38-in. (160 x 100 x 35mm). In addition to chassis mount, an optional DIN rail clip, mounting base, or Eurocard front panel are available.
