Schaefer announced the PRC-500 Series of DC/DC converters that provide 500 W of power in a compact, chassis mount package. The series has versions that meet industrial (EN60950) or rail (EN50155) standards. Standard nominal input voltages are 24 VDC, 48 VDC, 72 VDC, and 110 VDC. The PRC-500 Series provides efficient (up to 92 percent) conversion to adjustable 24 VDC and 48 VDC 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 series tout comprehensive protection circuitry against short circuit/overload, input reverse polarity, input under voltage or undercurrent, and output overvoltage. Remote sense, remote inhibit, LED indicators, and alarm signals are part of the standard design. A wide operating temperature of up to -25C to +75C 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 size of the PRC-500 Series measures 10.47” x 7.08” x 2.16”. In addition to chassis mounting, an optional DIN rail clip or 6U subrack plate are available.
