The Sorensen DCS33-33E is a 1 kW programmable DC power supply engineered for precision bench and production test environments. Built on switch-mode topology, it delivers continuous full output power across any voltage and current combination within its rated limits—0-33 VDC at 0-33 A. The unit combines high power density with a low-profile form factor, making it ideal for space-constrained installations.

– Key Features
• Dual 10-turn potentiometers provide high-resolution voltage and current adjustment
• Simultaneous digital display of output voltage and current settings
• Adjustable over-voltage protection (OVP) with front panel and remote control
• Remote sensing compensates for power lead voltage drop
• Selectable TTL, AC, or DC shutdown via external signal
• LED status indicators for temperature, OVP, mode, and remote/local control state
• Constant voltage and constant current mode indication
– Remote Programming & Control
Voltage, current limit, and OVP accept external command signals with user-selectable programming constants. Output monitoring provides remote feedback of OVP status, thermal shutdown state, and actual voltage/current levels.
– Optional Interfaces
Internal IEEE-488/RS-232 module (M9C) provides instrument control with voltage and current readback; supports 12-bit slave devices only. Isolated analog programming option (M51/M51A) available for voltage, current, and OVP command.
– Typical Applications
Manufacturing test, device burn-in, avionics qualification, telecommunications systems, process control, and laboratory R&D.
