DLM 3-4 kW - 2U Rack Programmable DC Power Supplies

The Sorensen DLM 3kW and 4kW Series programmable DC power supplies are designed to provide highly stable, continuously variable DC output voltage and current for a broad range of applications in a compact 2U (3½” high) chassis.

The 3 kW and 4 kW 2U rackmount DC power supply models have output voltages from 0-5 VDC to 0-600 VDC and a current range from 0-5A to 0-450A. The output rms noise is as low as 10 mV. The output will recover to 1% of its steady-state voltage within 1ms for a step load change of 100% to 70% or 70% to 100%. The front panel layout makes the series extremely easy to use. Control switches include power on, enable/ standby, and local/ remote.

Displays and indicators show programmed set points and operational control status. The programmed voltage, current, and overvoltage set points are displayed with two large 3½ digit LED displays. Operational Status LEDs indicate power on, shutdown, over temperature, overvoltage, constant current, and voltage mode status. Control Status LEDs indicate front panel lockout, remote control, and standby status. IEEE- 488.2 control LEDs indicate the error, service request, and remote address status.

The 3 kW DC Power Supply Models will accept 200*/230 VAC single phase and 200*/208 VAC three phase input power.

The 4 kW DC Supply Models will accept 200*/208 VAC, three-phase, or optional 400 or 480 VAC three-phase input power.

*Operating temperature below 40°C
