BK Precision 1762 Overview

This B+K Precision Triple Output DC Power Supply is a high quality, general purpose dc power source. It provides two “main” supplies with a 0-60 volt dc outputs and a “third” output with a 4-6.5 volt dc output. The “main” V supplies are adjustable with both coarse and fine voltage controls for precise stability and are capable of current output of 0-2 amps. The “third” supply has a current output of 0-4 amps, allowing it to handle extensive digital logic circuitry. Two large panel-mounted LED meter displays can monitor either the output current or output voltage of each supply.

The two “main” volt supplies can be operated independently or in one of two tracking modes. In the series tracking mode, the “B” Supply tracks from 5% to 100% of the voltage of the “A” Supply. Maximum current setting of the two supplies can still be set independently when in the series tracking operating mode. In the series tracking mode the “A” and “B” supplies are connected in series, allowing a single output of 0-120 V at up to 2 amps. In the parallel tracking mode, the two supplies are connected together in parallel, allowing a single 0-36 V output at up to 4 amps.

Both “main” volt supplies may be used in constant voltage or constant current applications. The crossover from constant voltage to constant current modes is smooth and automatic. LED’s indicate the “CV” (constant voltage) or “CC” (constant current) mode of operation. In constant voltage applications, a current limit may be preset. When load variations cause the current to reach the preset limit, the unit then regulates output current rather than output voltage. Current limits are adjustable from 5% to 100% of maximum.
