The 1696B Series of compact 200 W DC power
supplies are equipped with programming and
protection features commonly found in more
expensive performance instruments. Programming
features include list mode for repetitive operation
and 10 user-configurable voltage/current presets
for quick recall. These benchtop power supplies
also support adjustable voltage and current limits
to protect the device under test.
The front panel incorporates a numeric keypad,
rotary control knob, and a dedicated V-set/I-set
button for convenient control. The back-lit LCD
simultaneously displays voltage, current, and
power meter measurements with 4-digit
resolution.
Applications
Suitable for many applications including
repetitive test routines in R&D, production
testing, product evaluation, or in education
environments.

This series features USB and RS485 interfaces
for remote communication. Operating software
is included for list mode set up and logging
measurement data. Any of the three models in
this series can be combined for multi-unit control
of up to 31 power supplies.
