BK Precision 1735A DC Power Supply

The BK Precision 1735A is a single-output, digital DC power supply designed for laboratory and production environments. It provides adjustable voltage and current with coarse and fine controls, featuring dual 4-digit LED displays for simultaneous monitoring of output voltage and current. This unit operates in both constant voltage (CV) and constant current (CC) modes, with automatic and smooth crossover between them, indicated by LEDs. The design incorporates a pre-regulator to minimize internal power dissipation at lower output voltages. For increased power capabilities, two 1735A units can be connected in parallel to double the current output or in series to double the voltage output. Protection features include current limiting, reverse polarity, and overvoltage protection.
