Data Sheet Switching DC Power Supplies Models 1685B, 1687B & 1688B Features and Benefits B&K Precision models 1685B, 1687B, and 1688B are laboratory grade switching mode DC power supplies with high current output in a small, lightweight form factor. These power supplies provide various configurations of output voltage and current, and feature rotary encoder control knobs, which make setting voltage and current levels fast and precise. Its dual action push button allows the user to easily set both coarse and fine, voltage and current levels. control modes. Save up to three different presets of voltage and current values for quick recall. For remote control, an analog remote control terminal is accessible on the rear, or use the USB interface to communicate with the power supply via PC software or remote commands. Automatic CV/CC crossover operation Rotary encoder control for precise voltage and current setting Save up to 3 user-defined voltage and current presets for quick recall These features make the 1685B Series suitable for a wide range of applications including production testing, telecommunications, R&D, electronic field service, and university labs. PC software for remote control and external timed programming Analog remote control function Front panel auxiliary output In addition to its constant voltage (CV) and constant current (CC) modes, these high efficiency DC power supplies offer preset and remote Overvoltage, overtemperature, and overload protection Outputs / Model Variable Output Voltage Variable Output Current Technical data subject to change © B&K Precision Corp. 2012
