DLM 3-4 kW
|Model: DLM Series
Voltage: 5V - 600V
Current: 5A - 450A
Power: 3kW - 4kW
Overview: Programmable DC Power Supplies
The DLM 3kW/4kW Series partial obsolescence was announced on September 30, 2022 with Last Time Buy until September 30, 2023. The only models that will remain available are DLM5-350E, DLM8-350E, DLM16-185E, DLM5-450E, DLM8-450E, DLM16-250E, and DLM22-180E. The rest of the models are replaced by the Asterion DC Series.
The Sorensen DLM 3kW and 4kW 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.
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.
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 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.
*Operating temperature below 40°C
Features and Benefits

|Options and Accessories|
|M1||345-455 VAC, 47-63 Hz, three phase, 3 wire plus ground, Delta or Wye may be used (4 kW only)|
|M2||432-528 VAC, 47-63 Hz, three phase, 3 wire plus ground, Delta or Wye may be used (4 kW only)|
|M9E||SCPI compatible IEEE-488.2 and RS 232 interfaces (May not be combined with M51A or M85)|
|M13||Locking shafts (front panel potentiometers)|
|M51A||Isolated analog programming (May not be combined with M9C or M85). This isolation allows users to control power supplies not connected to a common ground. In addition, in systems with high ambient noise or with large ground loop currents the control ground can be isolated from the power ground eliminating problems.|
|M85||12-bit slave interface (May not be combined with M9E or M51A)|
|5361969-01||Paralleling Cable; one cable per slave unit|
|105-300-26||Rack slide kit|
