Abstract

PURPOSE: To make it possible to easily control high voltage in accordance with the setting value by the digital signal and also the simple constitution, by selecting the constant-voltage characteristics of Zener diode and forming the constitution by which optional control voltage can be obtained.
CONSTITUTION: The circuit is formed by Zener diodes D11W14, pairs of photocouplers 7W10, 7'W10', high voltage input/output voltage terminals 1, 2, and digital input terminals 3W6. When the terminal 3 becomes "H" level, the luminous diode 7 emits light and the phototransistor 7' is turned ON, therefore the constant-voltage which has been maintained by D11 is reduced and becomes conducting, and consequently voltage of the terminal 2 is controlled.
