Sorensen SGe Series

5kW-30kW economical programmable high power DC supply

Product Overview
The SGe is an economical, FET based, high switching speed, programmable, dc power supply alternative to SCR and IGBT based dc supplies.

Most topologies use either a MosFET or IGBT approach within their power stage to execute their power conversion topology. At the same time end users value low output ripple and noise in conjunction with achieving high slew rates. Both IGBT and SCR based designs typically run at much lower switching speeds requiring a larger LC output filter design for similar performance or require degrading ripple and noise performance in order to maintain competitive power densities. The filter design in this case may be balanced to trade off performance of response time with output ripple and noise and densities.

In contrast, our SGe line leverages the benefits of using high switching speed Mosfets requiring a much smaller output stage LC filter in order to provide competitive output ripple and noise performance and response time without compromising power densities. Available in two control versions, the SGe has basic analog controls, while the SGI provides intelligent control features

SGe: Real Value - Analog Control
The SGe, with its outstanding FET based power electronics, is available for customers requiring simple front panel analog controls or external control. With high performance power electronics the SGe provides essential features like 10- turn potentiometers for setting voltage and current, 3½ digit LED readout plus front panel over-voltage protection (OVP) preview/adjustment and reset.
