Three-phase SCR Power Voltage Regulator(The following abbreviated instrument),is based on digital technology as the core, with digital-analog integrated technology, contains phase-shift trigger and zero-crossing together, can choose the trigger freely. This instrument is used reliably and easily.

Instrument can be used with the regulator of a continuous PID current output, Can be used as three-phase electrical heating equipment of metallurgy, machinery, chemical and other industries that need high-power , Such as voltage regulator, power regulator of the electric kiln, electric furnace ;used that need three-phase rectifier、DC motor control speed and other occasions (speed range is not too large), instrument can also be used with inductive load.
