Compact, rugged DC/AC Inverter for Rail and Industrial Applications

Schaefer has announced the PRP-1500 Series 86% to 90% efficient pure sine wave inverters providing up to 1500VA of power in a flexible package that can be chassis mounted, DIN rail mounted or fits into a standard 3U Eurorack. The PRP-1500 Series has versions that meet industrial (EN60950) or rail (EN50155) standards.

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

All models in the PRP-1500 Series feature overload protection and an LED indicator for output OK or alarm conditions. A wide operating temperature of -25C to +70C allows for installations in extreme conditions and meets EN50155 Class 3. Emissions to EN61000-6-4 and EN60121-3-2 meet both industrial and rail standards and minimize interference to other sensitive equipment. Status and programming is controlled through the RS232 interface.

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

Modifications to standard units are available. In addition, Schaefer can design and manufacture fully custom solutions. PRP-1500 Series pricing is from $1186.00 at 100 pieces, with significant OEM quantity discounts.
