More

The DCS Series of 1 kW, 1.2 kW, and 3 kW DC programmable power supplies provides a highly reliable switch mode power supply platform. This switched-mode DC power supply utilizes unique packaging techniques to achieve continuous full output power (1 kW, 1.2 kW, or 3 kW) in any volt/amp combination within the rated output voltage and current limits in a low-profile chassis. This multi-range DC power supply family has an easy-to-use front panel with 10-turn potentiometers to adjust voltage and current settings that are displayed simultaneously. LEDs indicate overtemperature, remote programming, shutdown, and over-voltage protection, status, and constant voltage/current mode operation. The DCS 3 kW Models must have push-button control of the output standby mode, OVP reset, remote/local programming, and preview status of voltage, current, and OVP setpoints. The Sorensen DCS family programmable DC power supply can also be controlled remotely. Four analog control modes are standard as well as isolated analog control (option). Computer control can be accomplished over IEEE488.2 GPIB (option) or LXI-compliant Ethernet (option).

Sorensen DCS Series Specifications

Common
Meter Accuracy	1% of full scale + 1 count
Max. Voltage Differential from Output to Safety Ground	150 VDC
Remote Start/Stop and Interlock	TTL compatible input or 12-250 VAC (12-130 VDC) or a contact closure
Cooling	Internal fan, over temperature shutdown if internal heat sink exceeds set temperature
Remote Sense	The maximum allowed sense line drop is 4V per line (2V on the DCS 8/10V 1 kW/1.2 kW models and 1V/line for all 3 kW models). Line drop subtracts from the maximum available output voltage at full rated power.
Remote Programming	Enabled via external jumper on rear panel connector J3
Overvoltage Protection	Crowbar type adjustable from 5-110% of rated output using front panel control (local or remote program selectable via J3 jumper)
Remote Analog Programming Linearity	Typical error is less an 0.5% setting. Accuracy is 1% of rated output.
Regulatory	Certified to UL/CSA 61010 (Not DCS 3K) and IEC/EN 61010-1 CE Compliant (LVD and EMC directive)
