THYRISTOR REGULATOR
JB SERIES
JB series small and lightweight thyristor
regulators for single-phase loads are
characterized with high panel installation
density. 6 models for the rated current of
20A, 30A, 40A, 50A, 75A and 100A are
available for regulation of alternative
current power by the combination with a
controller or by manual control.
Two control systems, a phase-angle firing
system for continuous power control and a
zero-cross firing system, are built-in and
selectable for various applications and
power environment.
The applications include small electric
furnaces, calibration bath, casting dies
heating and heating units for laboratory
use.
■ Feature
• Compact structure
Compact, lightweight and high panel installation
density
• Phase-angle firing/zero-cross firing
The phase-angle firing system and the zero-cross
firing system can be selected by internal
dipswitches. You can select an appropriate system
depending on applications or power environment.
•Automatic frequency detecting function
• Linearization of input/output
characteristics
• Programmable soft-start time
With a built-in trimmer, the soft-start time and soft
up/down time are programmable. This function is
convenience to countermeasure a rapid change of
load voltage and input signal, and to prevent
overloading to loads by over-current.
• Built-in slope setting function
The slope of output to input signal can be adjusted
by a built-in trimmer. A slope-setting unit is
separately available, too.
• Built-in low-limit setting function
By the built-in low-limit setting function, the
variation band of output to on-off contact input
signal can be adjusted for sensitive control. A
low-limit setting unit is separately provided, too.
•Abundant Accessories
Separate setting units for slope and high/low
limit(s), and easy-to-mount external rapid fuse unit
are provided.
