    Sorensen DLM Series

    Product Overview

    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

    Sorensen DLM Series Specifications
    Common
    Front Panel Controls Knobs with 3½ digit digital displays to control output voltage and current settings. Power on/off switch, output enable/standby switch
    and local/remote switch. Voltage, current and overvoltage preview push buttons allow you to preview the programmed settings at any
    time; overvoltage limit is adjusted with a set screw accessible through the front panel.
    Displays and Indicators Voltage and overvoltage setting 3½ digit LED display, current setting 3½ digit LED display. LED indicators for power on, shutdown,
    remote, overvoltage protection, overtemperature and front panel lockout, constant voltage and constant current modes. IEEE-488.2 indicators include error, SRQ and address (M9E option).
    Overvoltage Protection Output overvoltage (resets by cycling the enable/standby switch)
    Cooling Internal fans with over temperature protection
    Rear Panel Control/Monitor
    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 <2V for models rated 5V to 16V, and <5V for all other models.
    Remote Sense Protection Unit will not be damaged due to misconnection of the remote sense leads
    Remote Programming Voltage, current (0-100%) and OVP (5-110%) of full scale can be programmed by selectable 0-5 VDC, 0-10 VDC, or 0-5 kΩ.
    Remote Monitoring Voltage or current can be monitored with user-selectable ranges, 0-5 VDC or 0-10 VDC
    Operational Features Master/slave parallel operation, up to 2 units can be connected in parallel with active current sharing control to within 10% of each supply. Series operation, up to 3 units of the same model type can be connected in series (consult manual). Negative terminal rated at 150 Vmax above ground

    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.
