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.
Low Voltage
Connection Using the load generator 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 generator.
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-2000 series has reverse voltage
protection. For details see the protection section on
page 79.
