Schaefer Intros Hi Efficiency DC/DC Converter
500W DC/DC power converter.
Hopkinton, MA — Schaefer has introduced the PRC-500 Series of DC/DC converters, which provide 500W of power in a compact, chassis-mount package. The PRP-500 Series has versions that meet industrial (EN60950) or rail (EN50155) standards.

Standard nominal input voltages are 24, 48, 72, and 110VDC. The PRC-500 Series provides highly efficient (up to 92 percent) conversion to adjustable 24VDC and 48VDC outputs that are tightly regulated to 0.2 percent or better. An ORing FET option allows for efficient parallel operation of multiple units.

All models in the PRC-500 Series incorporate comprehensive protection circuitry against short circuit/overload, input reverse polarity, input undervoltage or undercurrent, and output overvoltage.

Remote sense, remote inhibit, LED indicators, and alarm signals are part of the standard design. A wide operating temperature range of -25 to +75°C allows for installations in extreme conditions and meets EN50155 Class 3. Emissions to EN61000-6-4 and EN60121-3-2 meets both industrial and rail standards and minimizes interference to other sensitive equipment.

The compact PRC-500 Series measures 10.47 x 7.08 x 2.16-in. (266 x 180 x 55mm). Chassis mounting is standard; optional DIN rail clip or 6U subrack plate are available and other modifications are available.
