The BK Precision 1900B220V Programmable Single-Output Switching DC Power Supply, 16V/60A, 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. Its dual action push button allows the user to set both coarse and fine, voltage and current levels.

In addition to constant voltage (CV) and constant current (CC) modes, the high efficiency 1900B-220V offers preset and analog remote control modes. Users may 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. A remote sensing terminal is also available to compensate for voltage drop across load leads.

Built-in OVP (overvoltage protection), OTP (overtemperature protection), and OLP (overload protection) circuitry help prevent serious damage to the unit in case of power supply failure.
