DLM40-15 Sorensen DC Power Supply Used

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.

Software:

• IVI-COM, LabVIEW® or LabWindow®/CVI driver for Ethernet and IEEE-488.2

Regulatory Compliance:

• CE Compliant
• Low Voltage Directive (73/23/EEC) using EN 61010-1
• EMC Directive (89/336/EEC) using EN 61326 Certified to UL 61010-1, CSA C22.2 No. 61010.1 and IEC/EN 61010-1

Input:

• Voltage and Frequency 90-132 VAC or 180-264 VAC max, auto ranging, 47-63 Hz, single phase, 2-wire plus ground
• Current 11A maximum at 115VAC, 6A maximum at 230 VAC
• Connector IEC 320 with detachable line cord
• Power Factor 0.6, typical at full load; dependent on the impedance of the AC input

Output:

• Line Regulation Voltage: 0.005% of V max + 2 mV
• Current: 0.01% of I max + 2 mA
• Load Regulation Voltage: 0.005% of V max + 2 mV
• Current: 0.02% of I max + 5 mA
• Transient Response 500 μs to steady-state output voltage (within 0.1% of Vmax) for 50-100% or 100-50% load change
• Stability ±0.05% of maximum voltage or current over 8 hours after 30 minute warm-up time at fixed line, load and temperature
• Efficiency 84% typical at maximum output power
• Temperature Coefficient 0.02%/°C of maximum output voltage, 0.03%/°C of maximum output current. Change in output per °C change in ambient temperature, with constant line and load.

Environmental:

• Operating Temperature 0°C to 50°C (no derating)
• Storage Temperature -40°C to 65°C
• Cooling Internal variable speed fans with over temperature protection. Air intake is from the front and sides with exhaust at rear and sides for maximum rackmount packing density

Physical:

• Dimensions Width: 8.5” (216 mm)
• Height: 1U or 1.75” (44 mm)
• Depth: 17” (432 mm) Option M6 depth 20” (508 mm)

The Sorensen DLM40-15 programmable power supply 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 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.
