Třífázové tyristorové regulátory řady JW

JW series three-phase thyristor regulators

JW is a series of compact and lightweight three-phase power regulators. Two control systems (phase and group) are built into the unit. The control type is selected using the corresponding terminals. For phase control, the regulator can optionally be equipped with voltage, current or power feedback functions depending on the type of load. Remote control and monitoring of the controller operation is possible by connecting an external management unit.


Features:

  • compact construction
  • phase control / group control
  • optional operator panel - displays information about current, voltage, power, possibility to change parameters, regulator operation, RS422 or RS485 communication
  • disconnection alarm and current limitation
  • protection - fast fuses
