JW Series - Three Phase Thyristor Regulators

JW Series Three Phase Thyristor Regulator

JW series is three-phase thyristor regulator, which is compact, lightweight, and capable of high-density instrumentation. Controllability is improved using 6-arm control. For the control system, there are two systems available, phase control and zero-cross control which can be switched to use. For phase control system, there are: voltage, current, and power feedback types and no feedback type are available for selection according to heater characteristics.

Features

  • Compact all-in-one structure A slim structure with a narrow width achieves high panel installation density.
  • Setting communication unit (option) is available Displaying present voltage value, current value and power value, parameter setting and operation switching are available.
  • Disconnection alarm and current limit are equipped as standard.
  • Ample protective functions Various protective functions are offered: thyristor gate-off at over-current, blow out fast acting fuse at load short circuit, and thyristor gate-off at heat sink overheat. Alarm functions convenient for three-phase control such as phase sequence abnormality alarm and phase drop alarm are equipped.
