The BK Precision 1901B is a laboratory-grade switching mode DC power supply with high current output in a small form factor and lightweight package. The 1901B provides various configurations of high output voltage or high output current and makes setting voltage and current levels fast and precise through its dual action, coarse/fine rotary encoder control.

In addition to constant voltage (CV) and constant current (CC) modes, the high-efficiency DC power supplies offer a unique solution with its preset and remote control modes. Save up to three different presets of voltage and current values for quick recall. The remote control function allows the output power, voltage, and current to be adjusted without touching the front panel of the power supply. A remote sensing terminal is also available for use to compensate for long output line losses. These features make the 1901B suitable for a wide range of applications including production testing, telecommunications, R&D, service, and university labs.
