Schaefer Intros High Density 3000W DC/AC Inverter
3000 watt DC/AC inverter.
Ashland, MA — Schaefer has introduced the PRP-3000 Series of highly efficient, pure sine wave inverters that provide up to 3000VA of power. The new inverters are available in versions that meet industrial (EN60950) or rail (EN50155) standards.

Standard input voltages of 24VDC, 36VDC, 48VDC, 72VDC, and 110VDC are inverted to adjustable 120VAC or 230VAC outputs that are regulated to 4 percent or better. Units can be configured for three-phase synchronization. All models in the series have overload protection and an LED indicator for output OK or alarm conditions. A wide operating temperature 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 design. Units are highly efficient, with ratings ranging from 88 percent to 91 percent. Emissions to EN61000-6-4 and EN60121-3-2 meets both industrial and rail standards and minimizes interference to other sensitive equipment. Status and programming is controlled through the RS-232 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 up to 5000W that include a UPS.

Modifications to standard units are available. In addition, the company can design and manufacture fully custom solutions.
