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.
Full digital control
1mV /1mA measurement resolution
Compact size
Bright, readable LED display
Operating modes: CC/CV/CR
Input on/off control
High reliability due to OCP/OVP
(over current, over voltage)
protection
Storage for *40 groups, 4 setups
each
Easy operation
Features
Constant Resistance (CR) mode
In CR mode, the DC
load will sink a current
linearly proportional to
the voltage at the
terminals.

Constant Voltage (CV) mode
In CV mode, the DC
load will draw enough
current to keep the
voltage at the
terminals constant.
*40 groups are applicable for units with firmware version
1.60 or above. For versions below 1.60, 100 groups are
available. Go to “Verify firmware” section to determine
your instrument version.
