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)
