3.7.1 V_SET
There are two AC Source output setting modes: ALL and INDIVIDUAL. Users can set
V_SET on OUTPUT functional list (see 3.7) to fit the application. Then, the MAIN PAGE will
change corresponding to the mode.
If V_SET = ALL, the voltage settings of 3-phase output are all the same. The MAIN PAGE is
as below.
If V_SET = ALL_DELTA, the voltage settings of 3-phase output are all the same. But the
real output voltage between Line and Neutral is the setting value divided into √ 3 . This is for
3-wire connecting 3-phase AC power. For example, the output voltage between Line and
Neutral is 127V when set Vac = 220. But if the phase difference of each is 120° and 240°,
the voltage between Line and Line is 220V.
If V_SET = INDIVIDUAL, the voltage settings of 3-phase output can be set individually. The
MAIN PAGE is as below.
The procedures of setting from ALL to INDIVIDUAL are shown as below:
1. Move the cursor to the command of “V_SET=”. COUPLE = ALL_
2. Turn the RPG to change the option from ALL to
INDIVIDUAL, then press ENTER. COUPLE= INDIVIDUAL
