6.2.1 Controlmethod[ C-MD ]
Control method
Phase control
Cycle control
(1)Normalmode[ PA ]
It is general output method to divide control angle proportionally according to control input signal
and to output it. The below figure is for output characteristics. It may cause lack power and
overpower based on the center of control input.

(2)Staticvoltagemode[ U-FB ]
At low temperature coefficient load(iron, chrome, nichrome, etc) of electrical resistance, it outputs
constant output which is proportion to control input not to change output voltage for power supply
variation, load resistance variation.
