The dydac thyristor power controller is a heavy duty, fully Digital or Analog one, two or three phase power control unit for controlling the voltage applied to loads such as heating elements, thus, allowing temperature control while eliminating contractor switching and over/under heating.
The first in a series of digital or analog thyristor ( SCR ) power controllers incorporating protection functions.
Built in switching methods are:
1. Phase Control Firing
2. Zero Crossing Firing
3. Phase Control Power
Range: 15 A - 400 A , 220-1200V,
