The BK Precision 1901B220V Programmable Switching DC Power Supply, 32V/30A, 220VAC Line Input provides different configurations of high output voltage or high output current, adjustable through its dual action, course and fine rotary encoder control. 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. The 1901B-220V comes with built-in overvoltage protection, overtemperature protection, and overload protection circuitry. These protections help prevent serious damage to equipment in case of power supply failure.

This model comes with built-in OVP (overvoltage protection), OTP (overtemperature 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.

Control the instrument through remote control PC software or use programming commands.
