Overview:
The Sorensen DLM 600 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 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 600 is ideal for even the most demanding applications.
The DLM 600 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 DLM 600 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 ½digit LED displays.
Supplies can be connected in series or parallel. All models automatically accept any standard single phase input without manual set up.

Specifications:
| Common | |
| Remote Sense | The maximum load line drop is up to the full voltage rating of the supply. The drop in the load leads subtracts from the maximum voltage available for the load except as follows: maximum rated voltage is available at the load and voltage regulation specifications apply for line drops of<1V on DLM5-75 and DLM8-75, <2V for all other DLM600 models |
| Remote Programming | Voltage, current (0-100%) and OVP (5-110%) of full scale can be programmed by selectable 0-5VDC, 0-10VDC, or 0-5kΩ |
| Remote Monitoring | Voltage or current can be monitored with user selectable ranges, scaled to 0-5 VDC or 0-10 VDC |
| Operational Features | Master/slave parallel operation, up to 4 units of the same model can be connected in parallel, with active current sharing control. Series operation, multiple units of the same model can be connected in series, limited by 300Vpk between either output terminal and chassis. |
