The Sorensen DCS20-150E DC System Power Supply is a 3000-watt supply designed to provide highly stable, continuously variable output voltage and current for a broad range of development, system, and burn-in applications. The DCS-E Series employs high frequency switching regulator technology to achieve high power density and small package size. Features. Simultaneous digital display of both DC output voltage and current. Ten-turn potentiometer voltage and current controls permit high resolution setting of the output voltage and current from zero to the model-rated output. Front panel push button control of Output Standby Mode, OVP reset, Remote/Local Programming Mode selection, and preview of voltage, current, or OVP setpoints. External indicator signals for Remote Monitoring of OVP Status, Local/Remote Programming Status, Thermal Shutdown, and Output Voltage and Current. Current or Voltage Mode operation with Automatic Mode Crossover to respond to varying load requirements. Flexible output configuration where multiple units can be connected in series or in parallel to provide increased voltage or increased current. Remote Sensing to compensate for losses in power leads up to 1V per lead. Adjustable Over Voltage Protection (OVP). External Shutdown using AC, DC, or TTL compatible signals (positive or negative logic). Remote Voltage, Current Limit, and OVP Programming with selectable programming ranges. Specifications.
