Constant Power (CW) Mode

In this mode, the electronic load’s power consumption will be in accordance with the programmed value, regardless of the
input voltage. The CW mode can be set with front panel keys. The CW mode par ameters are discussed in the following

Transient Operation
Transient operation enables the electronic load to periodically switch between two load levels, as might be required for
testing power supplies. A power supply's regulation and transient characteristics can be evaluated by monitoring the supply's
output voltage under varying combinations of load levels, frequency, and duty cycle.
Transient operation can be turned on and off at the front panel or via PC control using the IT-E131 isolated communication
cable. Before turning on transient operation, you should set the desired mode of operation as well as all of the parameters
associated with transient operation. Transient operation may be used in the CC, CR, or CV or CW modes and can be setup
in continuous, pulsed, or toggled operation mode.

Continuous

Generates a repetitive pulse stream that toggles between two load levels and changes the state between value A and
value B.
