Product description
SVC series single and three-phase high-precision automatic AC voltage regulator is composed of contact type auto-coupler voltage regulator, servo motor and automatic control circuit. When the grid voltage is unstable and the load changes, the automatic sampling control circuit sends out The signal drives the servo motor to adjust the position of the auto-coupler carbon brush to adjust the output voltage to the rated value and reach a steady state. This series of regulators has a mains pass-through function. It has many advantages such as variety, specification and full appearance. It has the characteristics of no waveform distortion, high efficiency, reliable performance, long-term operation, etc. It has short delay and overvoltage protection functions. It can add long delay and undervoltage protection according to users' needs. The products are widely used in any application. The electric field is an ideal regulated power supply to ensure that your electrical equipment is operating normally.

Features
The regulator has small volume. High efficiency, small waveform distortion, fast voltage regulation, stable and reliable performance, complete protection functions, and long-term continuous operation.
Its structure consists of contact automatic voltage regulator, servo motor, automatic control circuit, etc. When the grid voltage is unstable or the load changes, the automatic sampling control circuit sends a signal to drive the servo motor and adjust the self-twisting voltage regulator carbon brush. The position of the output voltage is adjusted to the rated value and reaches a steady state.
