1 General Information
1.1 Product Overview
B&K Precision models 9103 and 9104 are multi-range power supplies differing from
conventional power supplies because voltage and current limits are varied to allow maximum
rated power to be delivered at any operating point. Contrast this to a conventional power
supply which has a maximum voltage and maximum current rating -- all operating points must
fall inside these limits.
This family of switching mode power supplies comes with a small form factor, auto cross-over
for constant voltage (CV) and constant current (CC), 3 voltage/current presets for frequently-
used settings, and remote control offering versatility for various applications.
The dual action (coarse/fine) tuning makes setting the voltage and current levels smooth,
precise, and fast. Setting, changing, and checking the current limit level can be done without
shorting the output.
Operating software through the USB interface allows turning the output power on or off and
the voltage and current can be adjusted without using the front panel. Up to 20 timed steps of
voltage and current, each with its own time duration from 1 s to 600 s, can be programmed for
up to 999 cycles.
A DC ramp or pulsed waveforms can be generated by the front panel or by the supplied
software with a preview of the final waveform. The 3 user defined presets facilitate quick
access to frequently used VI settings.
