SORENSEN DCR20-80B 20V 80A Single Output DC Power Supply

The Sorenson DCR20-80B Power Supply incorporates a single phase input SCR controlled regulator providing high efficiency and fully adjustable output power. It has excellent voltage and current regulation with automatic crossover. Features. Panel lights indicate operating mode. Remote voltage and resistance programming in voltage and current modes. Adjustable current limiting (overload/short circuit protection) with automatic recovery. Overvoltage protection standard. Specifications. Output Voltage: 0 to 20 Vdc. Output Current (40 C): 80 A. Constant Voltage Regulation: 10 mV. Constant Current Regulation: 200 mA. Constant Voltage Ripple (PARD): 65 rms/mV. Constant Current Ripple (PARD): 260 rms/mA. Voltage Regulation (Constant Voltage Mode): 0.05% or 10 mV, whichever is greater. Temperature Coefficient: 0.015%/C of Eo max. Stability: 0.1% Eo max for 8 hours after 30 minute warm-up. Remote Sensing: Maximum drop per load lead should not exceed 5% of Eo max. or 3 V, whichever is smaller. Transient Response: 50 ms (typical) to return to ± 2% band for step load change of 50 to 100% of full load. Current Regulation (Constant Current Mode): 0.25% of 10 max. line and load combined. Temperature Coefficient: 0.03%/C. of lo max. Stability: 0.15% of 10 max. for 8 hours after 30 minute warm-up.
