Switching DC Power Supplies

Models 1685B, 1687B & 1688B

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.

In addition to its 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. 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.

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.
