The specifications of the refrigerator ensure that it can work normally in the range of 180-240V, which is already very wide. In addition, the refrigerator has a protection circuit. If the voltage exceeds this range, the protection circuit will work, at most, replacing the fuse. So there is no need to install a voltage stabilizer in the refrigerator.
Extended data:
A voltage regulator is a device for stabilizing the output voltage. The voltage regulator consists of a voltage regulating circuit, a control circuit and a servo motor. When the input voltage or load changes, the control circuit samples, compares and amplifies, and then drives the servo motor to rotate, so that the position of the carbon brush of the voltage regulator changes, and the output voltage is kept stable by automatically adjusting the coil turns ratio.
There is no need to use a voltage regulator in the refrigerator, because the working voltage range of the refrigerator is quite wide, so there is no need to worry about the influence of low voltage on the normal operation of the refrigerator.
But the delay device is still needed, because it usually takes three or five minutes for the refrigerator to be electrified. If the power is turned on blindly within three minutes, it will pose a fatal threat to the compressor. The compressor needs a buffering process from shutdown to restart. In order to prevent the power supply system from calling again immediately after power failure, adding a delay device can better protect the refrigerator.
