BK Precision models 1900, 1901, and 1902 are laboratory-grade switching DC power supplies with high current output in a small, lightweight form factor. The 1900 Series provide various configurations of high output voltage or high output current and features rotary encoder control knobs, which make setting voltage and current fast and precise. 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 DC power supply offers 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 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 (model 1900 only) is also available to compensate for the voltage drop across load leads.

These features make 1900, 1901, and 1902 suitable for a wide range of applications requiring high current including production testing, telecommunications, R&D, service, and university labs.
