DLM Series - 4 kW - Sorensen Power Supplies DC

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

The 4 kW power rating is new to the Sorensen Family of power supplies. Both the 3 kW and 4 kW 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 1 ms 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.

The DLM 4kW Series includes the following models:

• DLM 5-450E
• DLM 8-450E
• DLM 16-250E
• DLM 32-125E
• DLM 40-100E
• DLM 60-66E
• DLM 80-50E
• DLM 150-26E
• DLM 300-13E
• DLM 600-6.6E

Displays and indicators show programmed set points and operational control status. The programmed voltage, current and overvoltage set points are displayed with two large 3_ digit LED displays. Operational Status LEDs indicate power on, shutdown, overtemperature, 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 error, service request and remote address status.

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

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