The HP Models 6256B, 6263B, 6264B, 6265B, 6266B, 6267B, 6271B, and 6274B are regulated DC power supplies. They utilize a transistor series-regulator combined with a triac preregulator for high efficiency, excellent regulation, and low ripple and noise. The output voltage and current can be adjusted using front panel controls or programmed remotely. These supplies offer constant voltage/constant current operation with automatic crossover. They are also equipped with an overvoltage protection crowbar circuit for load protection. Various operating modes, including remote sensing and programming, as well as auto-parallel, auto-series, and auto-tracking operations, are supported through rear panel connections.
