Description
THYRISTOR REGULATOR
JU SERIES
JU series small and lightweight thyristor regulators for single phase loads are characterized with high panel installation
density.
Two control systems, a phase angle firing system and a zero cross firing system, are built in and can be changed by remote contacts signal.
In the phase angle firing system, feedback types of voltage, current and power, and no feedback type are selectable depending on heating characteristics of heaters.
Three kinds of input signals, 4 to 20mADC, 1 to 5VDC and ON OFF contact signal, can be changed by terminal connections. Options of heater disconnection alarm function and current limit function are available.
The rapid fuse is built in all models and t he current transformer built in type is also available.
By the option setting unit (with communication function), it can be connected to the higher instruments such as PC and PLC ( signal converter may be required ) and centralize control the setting value and data up to 31 units.
