B&K Precision models 1900B, 1901B, and 1902Bare laboratory grade switching DC powersupplies with high current output in a small,lightweight form factor. The 1900B Series providevarious configurations of high output voltage orhigh output current and feature rotary encodercontrol knobs, which make setting voltage andcurrent fast and precise. Its dual action pushbutton allows the user to set both coarse andfine, voltage and current levels. In addition to constant voltage (CV) andconstant current (CC) modes, these highefficiency DC power supplies offer preset andremote control modes. Save up to three differentpresets of voltage and current values for quickrecall. The analog remote control function allowsthe output power, voltage, and current to beadjusted without touching the front panel of thepower supply. A remote sensing terminal (model1900B only) is also available to compensate forvoltage drop across load leads.These features make the 1900B, 1901B, and1902B suitable for a wide range of applicationsrequiring high current including productiontesting, telecommunications, R&D, service, anduniversity labs.
