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 system and 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 the characteristics 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 is available by communicating to a host unit. FEATURES Compact all-in-one configuration Narrow width unit enables a closed mounting. As they are using the same pitch of old JT series, a replacement by an old version is easy. Setting communications unit is prepared Displaying measured values of real time power voltage, current, electric power and also settings of each parameter, switching operation are available. Each parameter enables fine control. A unit having communications enable to monitor a data and to set up a parameter by the PC through RS422A / RS485. Disconnection alarm and current limit are provided as a standard Heater disconnection alarm function and current control function. (Heater disconnection alarm function is not applicable for SiC heater.) 6-arm control employed as standard 6-arm control is employed to all models to improve controllability. 6-arm control particularly in the transformer loading is the best for improving controllability, handling imbalance load and reducing harmonic noise. Various protective functions Thyristor elements are protected by gating off for over-current, melting of the rapid fuse for short circuit and gating off for over-heating of heat sink. Phase-sequence abnormalities alarm and open-phase alarm, which are suitable for three phase control are included. External transformer specification Damage by abnormal voltage such as surge is reduced by dividing synchronized signal input (control circuit power input) from main circuit and connecting external terminals.
