Three-phase electric voltage regulator
Detailed description

product description

Voltage regulators can be widely used in industry (such as chemical industry, metallurgy, instrumentation, electromechanical manufacturing, light industry, etc.), scientific experiments, public equipment, household appliances to achieve voltage regulation, temperature control, speed regulation, dimming and power For control and other purposes, it is an ideal AC voltage regulator.

The column electric voltage regulator has no distortion of the output voltage waveform (the distortion rate of the output voltage waveform is <1%). The column electric voltage regulator adopts an electric operating mechanism, which can operate in a closed loop for a long distance, reducing the labor intensity of operation. The output voltage can be adjusted from zero voltage, strong instantaneous overload capacity, no-load current, small no-load loss, high efficiency, low noise, and long life. Suitable for various inductive and capacitive loads!

Instructions:

1. Before use, it must be confirmed that the grid voltage and the input voltage should be consistent. Do not connect the input and output ends in reverse.
2. The voltage regulator should be connected to a protective ground wire and grounded reliably.
3. The pointer should be at the zero position before power on, and adjusted to the required voltage according to the voltage requirements.
4. The regulator is kept clean and protected from moisture. Ventilate during use.
5. In order to ensure the normal use of the regulator, the rotating part and the contact surface should be regularly inspected and maintained. This work should generally be performed when electricity is not available.
6. After using the voltage regulator, the voltage should be turned to zero.
