BK Precision 1685B series is a laboratory grade switching mode DC power supplies with high current output in a small form factor and lightweight package. It provides various configurations of output voltage and current, and make setting voltage and current levels fast and precise through its dual action, coarse/fine rotary encoder control knobs.

In addition to its constant voltage (CV) and constant current (CC) modes, the high efficiency DC power supply offers a unique solution with its preset and analog remote control modes. Save up to three different presets of voltage and current values for quick recall. The analog remote control function allows the output power, voltage, and current to be adjusted without touching the front panel of the power supply. These features make the 1685B Series suitable for a wide range of applications including production testing, telecommunications, R&D, service, and university labs.
