Optimum Cycle Control for High-precision Control with Low Noise

Smaller than a Normal Power Controller.
Enables low-noise power control in combination with zero-cross SSRs.
One Controller can control up to 8 SSRs.
RS-485 communications to set manipulated variables and heater burnout detection.
CE Marking.
Main upgraded function:
- Soft-start function added for lamp heaters.
- Three-phase optimum cycle control added for three-phase heaters.
- Combining with special CT for 150-A current detection.
  Note: The G3ZA must be used in combination with an SSR without the zero cross function when the soft-start function is used.

Control method

Phase Control
• Response is fast and high-precision temperature control is possible.
• Harmonics and noise are problems.

Phase Control

Optimum Cycle Control (High-precision Zero Cross Control)
• Outputs are turned ON and OFF each half cycle.
• Zero-cross control is performed.
• Noise is suppressed while achieving high-speed response with high-precision temperature control.
