JW SERIES
Three Phase Thyristor Regulator

JW series is a three-phase control thyristor regulators
having compact size and lighter in weight.
There are two control systems, the phase control systemand the zero-cross control system.
In the phase control systems, a type with the voltage,current and power feedback control systems and a type
without those feedbacks are available according to thecharacteristics of a heater used.
JW series is also capable of advanced three-phase
control based on 6-arm control and fine control setting by
the setting communications unit.
Furthermore, remote control and data monitoring isavailable by communicating to a host unit.
