Sorensen DLM8-450

The Sorensen 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 ( 3½¿ high) chassis.

The 4 kW power rating is new to the Sorensen Family of power supplies. 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.

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, 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.

Requires 208 / 240 VAC, three phase input power.

High Power Density 2U (3½ inches) high, 19 inches wide; no top or bottom clearance spacing required
