Sine Wave Inverters Provide Up to 3000 VA for Rail, Military and Industrial Apps
Thu, 10/13/2011 - 12:47pm
Schaefer announced a series of efficient, pure sine wave inverters that provide up to 3000 VA of power. The PRP-3000 Series has versions that meet industrial (EN60950) or rail (EN50155) standards. Standard input voltages of 24 VDC, 36 VDC, 48 VDC, 72 VDC, and 110 VDC are inverted to adjustable 120 VAC or 230 VAC outputs that are regulated to 4 percent or better. The units can be configured for three phase synchronization. All models in the PRP-3000 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. Remote inhibit and remote off are standard. Efficiency ratings range from 88 percent to 91 percent. 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 R-S232 interface.
