DC Connection
For purely DC operation, a resistor and capacitor
can be connected in parallel to the electronic load
to reduce oscillation. The capacitor and resistor
values are dependent on the load settings. Ensure
the capacitor ripple current is within allowable
limits.

Connection
Using the load with low voltage loads is generally
limited to over 1 volt (load module dependent). In
order to support low voltage loads, an auxiliary
power supply is needed to boost the voltage to a
range suitable for the load.
Precautions:

Take into account the combined power of the
load and auxiliary power supply.

Make sure the auxiliary power supply is able to
provide enough current.

Take into account any noise or irregularities
from the auxiliary supply.
The diagram below shows a typical connection.

WARNING
Using an auxiliary power supply may induce reverse
current. The PEL-2000B series has reverse voltage
protection. For details see the protection section on
page 82.
