B&K Precision Model 1687B is a compact, lightweight, laboratory grade switching mode DC bench power supply offering high current output. It provides various configurations of output voltage and current, and rotary encoder control knobs make setting voltage and current levels fast and precise. The dual action push button enables the user to easily set both coarse and fine voltage and current levels. In addition to constant voltage (CV) and constant current (CC) modes, the 1687B offers preset and remote control modes. Up to three different presets of voltage and current values can be saved for quick recall. For remote control, an analog remote control terminal is accessible at the rear of the instrument, or the USB interface can be used to communicate with the power supply via PC software or remote commands. Fields of application of the 1687B include production testing, telecommunications, R&D, electronic field service and university/college laboratory work.
