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.
For example, IT7815-350-90 rated power is 15kVA, can provide single-
phase/three-phase 15kVA DUT test, can also meet up to three single-phase
DUTs test. The output mode can be set to AC/DC/ACDC/DCAC.
