1900B - 

Models 1900B, 1901B, and 1902B are laboratory grade switching DC power supplies with high current output in a small, lightweight form factor. The 1900B Series provide various configurations of high output voltage or high output current and feature 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, these high efficiency DC power supplies offer 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 1900B only) is also available to compensate for voltage drop across load leads.These features make the 1900B, 1901B, and 1902B suitable for a wide range of applications requiring high current including production testing, telecommunications, R&D, service, and university labs.Features and Benefits
