• Smaller than a Normal Power Controller.
• 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
