  • Page 90 15. Phase angle / Zero cross Control Description The NC controller can directly drive the thyristor. In the phase angle control mode, the phase angle of the thyristor can be controlled to cut the sine wave. In the zero cross control mode, it can automatically detect the zero point to turn-on or turn-off sine wave, phase angle control and zero cross control are the use of cutting or turn-on/off the sine wave to achieve the power control The related parameters of Dehumidification Function are as below: Range...
