DC Electronic Loads
Selection Guide
Input current
Rated power
Input voltage
When selecting a DC load, it is important to
consider not only voltage and current
requirements, but also power ratings. The
power used when testing must fall within the
hashed region for the appropriate DC load.

DC Electronic Loads
The 8540 DC electronic load is a compact,
economically priced instrument that can
reliably test a 5 V power supply to 30 A and
do it continuously.
Features & Benefits
■ Operates between 0-60 VDC, 1 mA-30 A
(150 W maximum)
■ Constant voltage (CV), constant current(CC),
and constant resistance (CR) operation
■ Very compact and lightweight
voltage/low current and low voltage/high
current, which a single load may not be able
to handle. B&K Precision’s broad range of DC
loads will allow you to select the optimal
model for your requirements.

150 W DC Electronic Load
MDL Series
* The MDL252 is a dual-channel 250 W load module supporting a unique flexible power configuration with up to 250 W per channel and up to 300 W total.
■ Two current ranges: 3 A (1 mA resolution)
and 30 A (10 mA resolution)
■ Overcurrent and overvoltage protection
■ Short mode to simulate shorts
■ Save up to 160 instrument settings
The 8540’s performance is comparable to
most stand-alone bench DC loads, yet it does
the job at half the price and takes up half the
space on your bench.
