A true three-phase three-wire rectifier, the unit operates at 0.998 power factor with less than 5% THD. It can deliver 110% of rated current up to 40°C, and a reduced amount up to 80°C by virtue of its thermal current limit feature. Designed for positive ground applications, the normal output voltage ranges from 47 to 58 volts, with a test voltage adjustable down to 45 volts. AC service is wired internally to each PCU. A horizontal terminal strip is located on the left top of the bay. An optional Power Distribution Service Cabinet (PDSC) bolted to the left side of the bay facilitates bulk wiring in one or two AC branch circuit applications per bay. Distribution Distribution is divided into two rows, top and bottom. Each row has a flexible design that accommodates any combination of breakers and fuses, up to a 1200 amp maximum. There can be up to 24 (3-100A) breakers/fuses or LPS48E1, -48VDC, 10,000A Modular Power Plant up to 12 (100-800A) devices, or any combination. Each frame can support up to 24 (1-100A) fuses or breakers or up to 12 (600A) fuses per frame. This patented unique design allows total flexibility to configure each frame per required device without costly kits and restrictive panels. Monitoring Distribution elements of 100 amps and from no load to full load. The MCA also greater include a monitoring shunt and uses a patented algorithm to balance control and alarm (MCA) panel.
