4-2 Output Modes
When phase control is used as the control method, any of the following four
modes can be selected for the relationship of the control value to the output
value.
Control pro-
portional to
phase angle
(same as
G3PX) In this mode, the relation-
ship of the output phase
angle to the output value
has the same characteristics
as for the G3PX Power Con-
troller.
Control pro-
portional to
square volt-
age In this mode, the square of
the output voltage is propor-
tional to the output value.
When the load resistance is
constant, the output power
value is proportional to the
output value.
Control pro-
portional to
voltage In this mode, the output volt-
age is proportional to the
output value.
Constant-cur-
rent control
(Constant-
current Mod-
els only) In this mode, the load cur-
rent is proportional to the
output value. The duty set-
ting changes with the load
resistance. To suppress the
output current, use the duty
setting function to suppress
the duty.
