The BK Precision 1901B-220V is a laboratory-grade switching mode DC power supply with high current output in a small form factor and lightweight package. The 1901B-220V 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. These features make the 1901B-220V suitable for a wide range of applications including production testing, telecommunications, R&D, service, and university labs.

Have peace of mind knowing that these power supplies come with built-in OVP (over voltage protection), OTP (over temperature protection), and OLP (overload protection) circuitry. These protections help prevent serious damage to equipment in case of power supply failure.

Quickly use common voltage and current settings with a flip of the Recall preset switch. Up to three different presets can be set and recalled.

Use the included connector to wire up to an external variable DC voltage source or variable resistor to remotely control the power supply’s output voltage and current or to turn the output on/off.
