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.
