Load Connection
Warning:
To satisfy safety requirements, load wires between the electronic load and the device under test (DUT)
should have a current rating high enough not to overheat while carrying the short-circuit output current.
Never make connections between the electronic load and a DUT while the electronic load inputs are turned
ON and/or the DUT has live power at its output.
Before connecting the device to be measured to the electronic load, please remove the cover on the output terminals of
the load and cover it after completing the connection. Please pay attention to the type, length, and polarity when wiring.
Avoid using wires of minimum specification of heating, which are unable to supply good load regulation.
Generally speaking, if the wires are short enough, they can control a voltage drop of less than 0.5 V. In addition, bonding
them together can reduce induction and noise. Connect wire from positive terminal of module to positive terminal of
device. Similarly, connect the corresponding negative terminal. Figure 3.1 illustrates a typical connection of the module
with the device to be measured.
Figure 3.1 Module Input
There are two positive terminals and two negative terminals on the rear panel of every module. Single terminal connection
is adequate when the input current is less than 30 A.
