Regulators have constant voltage control circuit, and a servo motor and other components. Position changed when the input voltage or load changes, sampling control circuit, comparison, amplification, and then drive the servo motor, so that the carbon brush regulator, by automatically adjusting the turns ratio, so as to maintain a stable output voltage.
Regulators which of installation steps:
The first is the regulator input connected to the power distribution board and switchboard placement in line fuse, to ensure safe use of electricity. The electrical equipment is connected to the power supply output terminal regulator, input voltage electrical appliances must be consistent with the rated output of the regulator.
Turn on the power switch, indicator lights work. Observe the voltmeter indication value is normal, normal, after turning the power switch electrical equipment, can automatically adjust the voltage regulator, the normal power supply. Such as long-term electrical equipment when not in use, turn off the power switch, to reduce power consumption and extend the life of the regulator.
When elected appliances refrigerators, air conditioners and other equipment have the motor running, you should select more than three times the capacity of the regulator, in order to avoid the device starting current exceeds the regulator fuse current or overcurrent protection circuit breaker current, so that a blown fuse or circuit breaker tripping or not drop too much work.
Wire connected to the regulator should have sufficient load surface and prevents heat and reduce the pressure drop. After connect all input / outlet, you must first turn off the power to the load switch, then open the regulator, check the output voltage is normal, then turn on the load of the power switch.
