Compact, Rugged DC/AC Inverter from Schaefer
Compact DC/AC power inverter.
Ashland, MA — Schaefer is introducing its PRP-1500 Series of highly efficient, pure sine wave inverters that provide up to 1500VA of power in a flexible package that can be chassis mounted, DIN rail mounted or fit into a standard 3U Eurorack. The inverter series has versions that meet industrial (EN60950) or rail (EN50155) standards.

Standard input voltages of 12, 24, 48, 72, and 110VDC are inverted to adjustable 120 or 230VAC outputs that are regulated to 4 percent or better. Units can be configured for three phase synchronization.

All models in the PRP-1500 Series include overload protection and an LED indicator for output OK or alarm conditions. A wide operating temperature range of -25 to +70°C allows for installations in extreme conditions and meets EN50155 Class 3.

Remote inhibit and remote off are standard in the PRP-1500 design, and efficiency ranges from 86 percent to 90 percent. Emissions to EN61000-6-4 and EN60121-3-2 meet both industrial and rail standards while minimizing interference to other sensitive equipment. Status and programming are controlled through the RS232 interface.

The company's full family of pure sine wave inverters also includes other standalone modules starting at 250W of power, and higher power rack designs that include a UPS.

Modifications to standard units are available.
