Operation and Application

Chapter4 Operation and Application

This chapter describes operations of the keys on the front panel of the AC power

supply. The AC power supply must be in the local mode when controlled by the

front panel. The default mode is the local mode after the AC power supply is

turned on. In the local mode, the user can enable all functions of the power

supply through the front panel.

4.1 Select the Power Supply Mode

The IT7800 series provides multiple modes such as single-phase, three-phase,

reverse phase and multi-channel, which can be selected by the user through the

panel menu.

Under the reverse mode, the rated voltage will be extended to 200%.

The multi-channel function allows users to test 3 independent DUT at the same

time without adding additional hardware configuration.

The operation steps are as follows.

1. Press [Shift] + (System) enter to system menu.

2. Under the Source setting interface, touch the screen or rotate the knob to

select the Phase and set the power supply phase mode.

Single Phase

Under the single phase, the power supply works as a single phase power supply.

the output mode can be set to AC/DC/ACDC/DCAC.

Three Phase

Under the three phase mode, the power supply works as a three phase power

supply. the output mode can be set to AC/ACDC.

Reverse Phase

Under the reverse phase, the power supply works as a single phase power

supply, and the rated voltage will be extended to 200%. For example, AC power

supply rated voltage is 350V, under the reverse phase mode, the reted output

voltage is 700V. And the output mode can be set to AC/DC/ACDC/DCAC.

Multi-channel

Under the Multi-channel phase, the power supply works as a single phase power

supply and have three channels.

The multi-channel function of the IT7800 series allows users to test 3

independent DUTs at the same time without adding additional hardware

configuration. In the traditional solution, the user needs to configure 3 AC power

supplies; and one IT7800 device can meet multi-channel testing requirements.

Under the Multi-channel mode, the parameters can be set independently. The

output mode can be set to AC/DC/ACDC/DCAC.
