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 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 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 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 set up.

High Power Density
600 watts in 1U (1.75 inches) high, half rack (8.5 inches) wide; no top or bottom clearance spacing required.
Near Linear Ripple & Noise
Ripple as low as 2.5mV rms, noise as low as 15mV p-p.
Remote Control
16 bit programming through LXI -compliant Ethernet LAN / RS-232C (Option M130)
12-bit programming through IEEE-488.2 / RS-232C (Option M9G)
Standard analog programming 0-5V, 0-10V, or 0-5k?.
isolated analog programming (option)
Pushbutton Preview
Overvoltage protection, voltage and current preview buttons allow viewing these set points at any time with or without the output enabled
Active Down Programming
Standard internal circuitry to speed up response time to down programming changes
Universal AC input
Easy master/slave paralleling with active current sharing
Software
IVI-com driver for M130 option
Labwindows CVI driver for M9G option
Labview driver for M9G option

M130 – Ethernet/LAN Option (16 bit)
M6- Disconnect & Polarity reversal relays (10V to 300V models only. This option requires one of the following options: M9G, M85, M130 or M131) Output disconnect and polarity reversal relays controlled via SCPI commands. An SPST relay is in line with each output lead.
M9G – IEEE-488.2 and RS-232C Interfaces
M51A – Optically Isolated Analog Programming and Monitoring. 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 – Multichannel Slave Interface
M131 – Multichannel Slave Interface (16 bit) (M130 Master ONLY)
