Enables low-noise power control in combination with zero-cross SSRs. (See note.) One Controller can control up to 8 SSRs. RS-485 communications to set manipulated variables and heater burnout detection. The Smart FB Library for the G3ZA can also be used. CE Marking Main Upgraded Functions Soft-start function added for lamp heaters. Three-phase optimum cycle control added for three-phase heaters. Combining with special CT for150-A current detection. Note: The G3ZA must be used in combination with an SSR without the Refer to Safety Precautions on page 9. zero cross function when the soft-start function is used.
