Question
What is phase control?
Answer
Phase control is control method in which the output amount is changed each half cycle. It enables high-precision temperature control.
Analog control of the output power is possible by receiving a 4 to 20-mA current output signal from the Temperature Controller.
The high-precision control makes the Temperature Controller resistant to external interference and the small heat shock means the heater life can be extended.
Note: Noise is generated, however, because it is not a zero-cross circuit.
