THYRISTOR REGULATORS Single-phase JB - 1

PERFORMANCE SPECIFICATION Separate purchase is required. Auto/manual switch \Slope setting knob Weight: 600g Specifications subject to change without notice. Printed in Japan (I) 2001.1 CHINO CORPORATION E-mail: inter@chino.co.jp Website: http://www.chino.co.jp/ THYRISTOR REGULATOR 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 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 • Compact structure Compact, lightweight and high panel installation • 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 • 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 • 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 - Rated current
