Data Sheet
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 efficien-
cy 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.
