Thyristor Regulators Thyristor Regulators JW Series Three Phase Thyristor Regulator     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. Features Compact all-in-one configuration Setting communication unit is included Heater disconnection alarm and current limit are included as a standard Controllability is improved with 6-arm control Imbalanced alarm function equipped as standard Various protective functions Models Rated Current Power voltage 200V AC 400V AC 10A JW20010N00 JW40010N00 20A JW20020N00 JW40020N00 30A JW20030N00 JW40030N00 50A JW20050N00 JW40050N00 75A JW20075N00 JW40075N00 100A JW20100N00 JW40100N00 150A JW20150N00 JW40150N00 200A JW20200N00 JW40200N00 250A JW20250N00 JW40250N00 300A JW20300N00 JW40300N00 400A JW20400N00 JW40400N00 500A JW20500N00 JW40500N00 750A JW20750N00 JW40750N00 1000A JW20X00N00 JW40X00N00 *Control systems and other optional specifications are confarmed.
