The HP 6267B high-performance Constant Voltage/ Constant Current employs a transistor series-regulator / triac-preregulator circuit to achieve high efficiency, excellent regulation, low ripple and noise, and moderate programming speeds in a compact full-rack width package, Separate coarse and fine voltage and current controls allow the voltage and current outputs to be varied from zero to the maximum rated value. Crossover form constant voltage to constant current operation occurs automatically when the load current exceeds the value established by the current control settings. Additional features include built-in overvoltage crowbar protection; remote error sensing; and auto-series, auto-parallel, and auto-tracking operation. The crowbar trip point adjustment and associated overvoltage indicator are conveniently located on the front panel. Auto-series, auto-parallel, and auto-tracking connections should ordinarily include no more than three supplies. Specifications. DC Outrput: 0 to 40 VDC, 0 to 10 A.
