Basic Operations

Chapter3 Basic Operations

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.

3.1 Output On/Off Operation

[On]/[Off] button on the front panel are used to control output switch. [On]

button lighted indicates the power supply output is on and the [Off] button

lighted indicates the power supply output is off. The initial state of AC source is

OFF.

NOTE

Make sure you have connected AC source and DUT very well, then press [On] button to

minimize shock hazard.

3.2 AC Output Mode

If user set AC Mode, the instrument will simulate AC power supply. The default

set of IT7600 series power supply is AC Mode. Set the output parameters of the

power supply in the main interface, including the output voltage, output

frequency, output start phase and output stop phase. Select the corresponding

parameters by pressing the Up and Down keys on the front panel, as shown in

the figure below.

 AC: AC voltage value. Setting range is different among Auto, High and Low

range. Refer to 9.1 Main technical parameters for more details.

 Freq:

Frequency with range of 10-5KHz.

 Start: Start phase angle

 Stop: Stop phase angle
