Programmable AC Source 6460/6463/6490 User’s Manual
3.2.3.1 Setting Output Voltage and Frequency
The maximum output voltage of ONE power stage is limited by the peak
value of the waveform, which is about 425 Vpeak. 6463, 6490 have
three power stages that can be selected in three phases or one phase
(parallel). 6460 has two power stages that can be selected in series or
parallel. The output is programmed in units of RMS volts. For a sine
wave, the maximum AC voltage of ONE power stage that can be
programmed is 300 V. So, for 6463, 6490 the max. Line to Line voltage
is 519 Vrms in 3-phase mode, and 300 Vrms in 1-phase mode. For
6460 the max. voltage is 300 Vrms in parallel mode, 500 Vrms in series
mode. The set voltage that we program here is just for each power
stage. If we want to get 400 Vrms output of 6460 in series mode, we
have to program 200 V on the display. For other waveforms, the max.
voltage may be different.
When you turn on the AC source, the state of default output is set in the Configure menu of
Power on output status. Set the output as V=135.2 Vrms, F=50.0 Hz as follows:
1. After you have powered on the AC source, and accomplished the self-test (or exited from
any other menu by pressing
QUIT), the LCD will display a main operational picture on the
screen as follows (on the next page):
Display of Cursor
The line where the cursor stays indicates that the AC
source is waiting for the input of the voltage value. V= _ 0.0
2. Input the value of V as 135.2 by pressing 1 , 3 , 5 ,
. , 2 , ENTER to set voltage of 135.2 Vrms, or
using data entry in section 3.2.2. V=135.2 F= _ 60.00
