   The Sorenson DCS40-75 Power Supply is a 3000W supply designed to provide highly stable continuously variable output voltage and current for a broad range of development system and burn-in applications. The Sorenson DCS40-75 3 kW Models have push button control of the output standby mode, OVP reset, remote/local programming and preview status of voltage, current and OVP set points.

Input Voltage and Frequency

  • 3 kW: 190-250 VAC, three phase, 14A typical, 47-63 Hz; or 200-250 VAC, single phase, 26A typical, 47-63 Hz
  • Note: Maximum power output of 3 kW supplies must be limited to 2.5 kW for single phase input
  • Soft Start: Line current is lower than full load peak value during turn-on or power application after restart


  • Operating Temperature: 0°C to 50°C (no derating), 50°C to 70°C (derate 2%/°C above 50°C)
  • Storage Temperature: -55°C to 85°C
  • Humidity Range: 0 to 80% RH, non condensing
  • 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 at internal heat sink temperature of 90°C
  • Remote Sense: The maximum allowed sense line drop is 1V (0.5V on the DCS 8-125E model)
  • Remote Programming: External jumper via 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)

Voltage Resolution: 0.02%

Regulation (Line or Load)

  • Voltage: 0.1%
  • Current: 0.1%

Transient Response: Typically recovers in <1 ms to 1% of steady-state output voltage (within 1% of Vmax) for 70-100% or 100-70% load change. 500 μs typical

Stability: ±0.05% of maximum voltage or current over 8 hours after 30 minute warm up time at fixed line, load and temperature

Temperature Coefficient: 0.02%/°C of maximum output voltage; 0.03%/°C of maximum output current
