Shimaden PAC18 Single Phase Thyristor Power Regulator

A PAC18 is a Thyristor for smooth, fast switching of power loads for ultimate control.
Part Number: PAC18
Call for pricing

As a succession device for the PAC15 and PAC16 Series which achieved a record
of long-term durability and reliance, the PAC18 Series thyristor power
regulator pursues an even higher level of functionality and safety.

Features:

  • Easy Front Key Setting
  • A 7-segment LED displays input and output values and various other parameters.
  • Slow-Up, Slow-Down Function
  • Output Current Detection Function (Optional)
  • Parameter Setting Function (Optional)
  • Universal Power Supply (100 ~ 240 V AC)
  • Automatic Frequency Function (50/60 Hz)

Functions:

  • Automatic detection of power frequency 50/60 Hz
  • Control circuit power supply is 100 V ~ 240 V common: this corresponds to a wide power/voltage range.
  • Output current detection function (optional) available, adaptable to overcurrent protection, current limit function and alarm output function (power failure, overcurrent, heater break detection and hardware error)

Note: A power filter is used in conjunction with the Tyristor for CE Compliance. See brochure
