Description
The Sorensen SGA400/50 400 Volt, 50 Amp, 20kW DC Power Supply is designed for exceptional load transient response, low noise and the highest power density in the industry. With a full 15 kW available down to 20VDC output in a 3U package the SG leads the industry in power density. The power density is enhanced by a stylish front air intake allowing supplies to be stacked without any required clearance between units.
At the heart of the Sorensen SGA400/50 is a 5 kW power module. With 400 Volts, 50 amps of output capability per unit, you can combining Sorensen SGA400/50 chassis can achieve power levels up to 150 kW. Paralleled units operate like one single supply providing total system current.
Sorensen SGA400/50 Features:
- Remote Sense: Terminals are provided to sense output voltage at point of load. Maximum line drop 5% of rated voltage per line for 40-100V models, line drop 1V of rated voltage per line for 10-20V models, 1.5V for 30V models, 2% of rated voltage per line for models 160V and greater. (Greater line drop is allowed, but output regulation specifications no longer apply).
- Parallel Operation: Up to 5 units may be paralleled for additional current within the power supply single-unit specifications, with exception of the DC output current set accuracy. Additional paralleled SG units will add 0.3% inaccuracy per unit. To parallel more than 5 units, contact factory.
- Series Operation: Up to 2 units (see Output Float Voltage)
