DLM 600 - 1/2 Rack Programmable DC Power Supplies

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

With the use of Zero Voltage Switching (ZVS) technology, these supplies can 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 1/2 rack DC power supply is ideal for even the most demanding applications.

The DLM 600 variable DC power supply series is 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 programmable DC 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 DC power supply 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 3-1/2-digit LED displays.

DLM 600 near-linear DC power supplies can be connected in series or parallel. All models automatically accept any standard single-phase input without manual setup.
