About the 8540
The B&K Precision 8540 DC electronic load (60V/30A/150W) can
sink DC current in constant current, constant voltage, and constant
resistance modes. Measured values have 10 mV and 1 mA
resolution. Shorts can be simulated. Storage is provided for up
to *40 groups, with 4 instrument setups per group. The instrument is
easy to use and will find many uses for testing DC power supplies,
batteries, and DC to DC converters.
Constant Current (CC) mode
In CC mode, the DC load
V
draws a constant current
regardless of the voltage on
its terminals.

*40 groups are applicable for units with firmware
version 1.60 or above. For versions below 1.60, 100
groups are available. Go to
