These units have been fully tested for voltage, current, and OVP functions. Units work as they are supposed to. They have option M39 M85. The units have  RS232, RS485, Digital IO. We have 8 units in stock so the unit you receive may not be the exact unit in the photos but they are all in similar condition with some small scratches or nicks in the front panel overlay.

Product Overview

The Sorensen DLM 600W series of programmable power supplies is designed to provide continuously variable output voltage and current for a broad range of applications in a compact 1U (1.75 inches) high, half-rack (8.5 inch) wide chassis.

With the use of Zero Voltage Switching (ZVS) technology, these supplies are able to achieve exceptionally low, near-linear ripple and noise rivaling larger and more expensive linear power supplies. In addition, the high efficiency and fast load transient response assure that the DLM is ideal for even the most demanding applications.

The Sorensen DLM 600W models are ideal for high density multiple output rackmount requirements or low profile benchtop applications. Output voltages from 0-5VDC to 0-300VDC and currents from 0-2A to 0- 75A are available.

The cooling air intake is at the front and sides with exhaust at the rear and sides. Variable speed fans are controlled as a function of ambient air temperature and load, thus reducing acoustic noise and increasing fan life. This allows supplies to be stacked one directly on top of another without space in between, yielding maximum rackmount packing density and a wide operating temperature of 0-50° C. An optional rackmount kit is available to easily mount one or two units side-by-side.

The front panel layout makes the Sorensen DLM 600W series easy to use. Voltage and current can be set from individual 10-turn potentiometer knobs. Control push buttons include power on, output on, local/remote, voltage/ current preview and overvoltage protection preview. Set-point or actual voltage/ current values can be viewed 
on two 3-½ digit LED displays. The DLM 600W can also be controlled through IEEE488.2 GPIB (option) or LXI-compliant Ethernet (option).

Supplies can be connected in series or parallel. All models automatically accept any standard single phase input without manual set up.
