The 6477C Power Supply is a SCR-regulated power supply designed for applications requiring a fixed or variable DC source with moderate regulation and ripple. Constant-Voltage/Constant-Current type and provides a DC output from 0 to 220 V @ 0 to 50 A. Large easy-to-read meters continuously monitor output voltage and current. Input and output power, remote sensing, remote programming, and auto-series, -parallel, and -tracking connections are made to bus bars and terminal blocks on the rear panel. Also incorporates reverse voltage protection and a fused AC input. Operates from 115 VAC ?10%, single phase, 57-63 Hz.
