Series WTC

Simple

  • The WTC controls tip heater circuits only 11V-5.0A). Pair the WTC with any 200V controller and you can now control tip heater-enabled Seiki nozzles.
  • The color touch screen panel is simple and easy to use. Switch between Japanese, English and Chinese with the touch of a finger.
  • Valve open/close timing control is standard.
  • The tip heaters and the valve open/close timing can be controlled from one screen, for smooth molding operation.
  • Operates across a power source range of AC200-AC240V without the need for conversion components. Adjustment is made on the transformer’s input terminals.

Durable

  • Conforms to CE standards. (RoHS compliant) Designed to withstand ambient noise as well as radio interference.

Reliable

  • The tip heater’s closed-loop current control ensures stable production even in environments with unsteady power supply.
  • The WTC monitors the system for electrical power overload or any break in the tip heater circuit. An alarm will sound and the system will be shut down if trouble occurs in the tip heaters or peripheral equipment.
  • Employs a true RMS current control circuit, to provide precise current control even under poor or unstable power source conditions.
