JW Series is compact lightweight three-phase control thyristor regulators enabling high-density instrumentation. The methods of control are divided into two ways, the phase control and zero-cross control. In the phase control systems, a type with the voltage, current and power feedback control types and a type without those feedbacks are available according to the characteristics of a heater used. JW Series are also capable of advanced three-phase control based on 6-arm control and fine control setting from the setting communication unit. Furthermore, remote control and data monitoring is available by connecting to a host unit.
