(5)Fixedcyclecontrol[
F-CY
]
During xed cycle (60 cycles) of load power, it repeats ON/OFF cycle as constant ratio according
to control input signal and controls the power supplies on the load.
• Fixed cycle (60 cycles) control – When controlling output as 40%
(6)Variablecyclecontrol[
U-CY
]
Variable cycle control controls required power using min. cycles of AC sine wave according to
control input signal and optimize temperature changes of the subject.
• Variable cycle control – When controlling output as 30%
• ON/OFF control method [
ONOF
]
The method when control input is OFF, output is OFF(0%), when it is ON, output is ON(100%).
