How To Check The Power Consumption Of Voltage Stabilizer?

If you want to calculate the power consumption of electrical appliances in AC circuits, you must know the following parameters:

Efficiency, power factor, supply voltage, operating current of the machine

Power consumption = voltage × current × power factor × efficiency × power consumption time

Generally, the power consumption of a transformer can be measured when the transformer is unloaded and calculated according to the formula. However, the power consumption of a Wide Range Voltage Stabilizer machine is not as simple as that of a transformer, because there are many types of voltage stabilizers. Commonly used are AC voltage stabilizers, DC voltage stabilizers, and integrated voltage stabilizers. The designs are very different. There are electronic voltage stabilizers and mechanical voltage stabilizers, and the efficiency of copper wire and aluminum wire is also different. At present, the power factor of an excellent voltage stabilizer is about 85%, and the no-load loss is about 0.1%. The power factor of an integrated voltage stabilizer with a transformer is 75%, and the no-load loss is about 5. If it is a DC voltage stabilizer with a transformer, the power factor is 60%, and the no-load loss is about 10%. Moreover, the efficiency changes with the load. At the same time, when the input voltage is high or low, the greater the corresponding compensation transformer compensation, the greater the loss. Therefore, the power consumption of the voltage stabilizer will be determined according to the power factor, working efficiency, voltage change, and current. To know the loss of the voltage stabilizer you are using, you can connect the voltage stabilizer to the circuit, connect an AC ammeter in series in the circuit connected to the power supply, and connect a voltmeter to the AC power supply. Observe the values ​​of voltage and current at the same time. The product of voltage and current is the no-load loss of the voltage stabilizer.

There is an unchanging law that the better the quality of the voltage stabilizer with the same power and the same voltage stabilization method, the lower the loss. So I remind all friends that you can't be greedy when buying a voltage stabilizer. The extra power consumption in a year may be higher than the price difference.
