The Sorensen DCS8-125E is a 1000W programmable DC power supply delivering 0–8 VDC at 0–125 ADC with continuous full output power across its entire voltage and current range. Built on a proven platform with an extensive installed base, this 1U rack-mount unit combines high power density with precise control, making it ideal for development, system integration, and burn-in test environments.
Technical Specifications
Electrical Performance
• Output: 0–8 VDC, 0–125 ADC
• Input: Selectable 100–132 VAC (20A) or 200–250 VAC (10A), 47–63 Hz single phase
• Line regulation: 0.1%
• Load regulation: 0.1%
• Stability: ±0.05% of maximum voltage or current over 8 hours (after 30-minute warm-up at fixed line, load, and temperature)
• Transient response: Recovers to within 1% of steady-state output in less than 1 ms for 70–100% or 100–70% load change; 500 μs typical
• Meter accuracy: 1% of full scale + 1 count
Operating Modes
Constant Voltage (CV) and Constant Current (CC) with automatic crossover. Overvoltage protection (OVP) is adjustable from 5–110% of output voltage range using crowbar topology.
