Sorensen SGI Series Modular Programmable DC Power Supply 5kW – 30kW
Description
Sorensen SGI Series Modular Programmable DC Power Supply 5kW – 30kW represents the next generation of high power programmable DC power supplies. The SG Series 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, and 12kW at 10Vdc and 1200ADC in a 3U package, the SG leads the industry in power density. The SG provides models up to 1000Vdc at 15amps. 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 SG series is a 5 kW power module. Depending on the output voltage, one to six modules can be configured in a single chassis to deliver 5 kW to 30 kW of power. Combinations of these chassis can then be easily paralleled to achieve power levels up to 150 kW. Paralleled units operate like one single supply providing total system current. Available in two control versions, the SGA has basic analog controls, while the SGI provides intelligent control features.
(Sorensen General purpose Analog) The SGA, with its industry leading price performance, is available for customers requiring simple front panel analog controls or external control. With the same high performance power electronics as the SGI, the SGA provides essential features like 10- turn potentiometers for setting voltage and current, 3 ½ digits LED readout plus front panel over-voltage protection (OVP) preview/adjustment and reset.
Features
