Voltage Stabilizer Buying Tips

1. It is recommended that you choose a voltage stabilizer that is three times larger than the actual power because, in practice, voltage stabilizers have to overcome the surge impact of commercial power and start the impact of inductive load (such as refrigerator, air conditioner, and electric motor). When choosing a contact automatic voltage regulator in the purchase of a voltage stabilizer, the rated output voltage regulator should have a larger margin than the switched automatic voltage regulator. In addition, it is necessary to check the appearance, quality, and technique, ensuring that buttons, switches, and other operations are flexible and reliable, spare parts are tight and there is no sound of objects rolling in the machine when shaking the device components, otherwise, there are foreign bodies in the device.

2. The rated total output of the automatic voltage regulator should be properly selected (total capacity power of household appliances*3). The outline structures of automatic voltage regulators include desktop voltage regulators, wall-mounted voltage regulators, dual-purpose of desktop and wall-mounted voltage regulators, as well as floor-type voltage regulators. It is recommended that you should choose different styles according to the location of installation, main use, and installation capacity.

How can I size the voltage stabilizer when used for a motor?

How can I size the voltage stabilizer when used for a motor?

ATO Responded

Just make the voltage stabilizer 1.5 times motor capacity.

Voltage regulator related issues

Ok. So there is definitely no need to go bigger than 15kVA when the input power is 220V / 63A.
What about the question re what type of AVR it is?
Is it a simple servo motor sliding contact type or something more sophisticated?

Yes, it is a simple servo motor sliding contact type.

Capacity of automatic voltage stabilizer

Hi. I'm looking at the ATOSVC-15kVA. Please explain the reason behind "The power capacity of voltage stabilizer needs to be 1.5~2 times greater than the load power". Also, what type of AVR is this? Eg Is it servo motor controlled with sliding contact?

From: Josephl | Date: 27/08/2021

Was this review helpful? Yes No (0/0)

ATO Responded

Let me check. Yes, usually the input power supply capacity should be 1.5 times the voltage stabilizer capacity, which depends on the load capacity you are using.
