Teach You How To Quickly Select A Static Voltage Stabilizer

In fact, there are two ways to choose Static Voltage Stabilizer, such as finding a partner. One is to state your requirements and let others introduce you; the other is to understand (the partner) according to your requirements and find the most suitable product for yourself. Here I recommend the first way to save time and effort. Regarding the question of how big a static voltage stabilizer should be selected, 30% of customers will ask. For this question, I will answer it in detail again. First of all, you need to know what are the conventional parameters for selecting a static voltage stabilizer, and then choose a static voltage stabilizer that suits you based on these parameters.

1. Convert capacity to power?

Voltage stabilizers and transformers are generally defined by capacity kilovolt-amperes (KVA), and their power factor is 0.8. The power used by the voltage stabilizer is kilowatts (KW) = kilovolt-amperes (KVA) × power factor, such as a voltage stabilizer 20KVA = 20x0.8 = 16KW.

2. Input voltage range?

I need to know the mains voltage range and the input voltage range of the voltage stabilizer, requiring that the voltage range of the mains must be within the voltage range of the voltage stabilizer. Generally, the voltage range of 380V is (304-456V). The range of 220V voltage regulator is (176-264V). If your mains voltage is not in this range, you need to request technical support.

3. How much power is used?

Before purchasing a voltage stabilizer, you must first know what electrical appliances are used and how much total power is used.

4. How much power is amplified?

The voltage stabilizer capacity safety factor is set. The voltage stabilizer should amplify the actual power used. The conventional amplification is 1.2 times, 1.5 times, 2 times, 3 times, and 5 times. The specific amplification multiple depends on the current size of the electrical inductive load used. If you choose a smaller one, the voltage stabilizer will burn out, and if you choose a larger one, it will be a waste. I suggest that the specific amplification multiple should refer to the opinions of the sales technician.

5. Voltage stabilization accuracy?

Voltage stabilization accuracy is the core technology of the voltage stabilizer. The higher the voltage stabilizer accuracy, the higher the price. There are few voltage stabilizers with an accuracy of ±1%, and it is considered good if the voltage can be stabilized within 3%. The voltage stabilization accuracy requires high precision equipment.

Example: If your equipment (air conditioner) voltage = 220V, power = 5000W, you cannot choose 5000VA when choosing a voltage stabilizer, that is, the selected voltage stabilizer must be at least 1.5-2 times the power used. So you should choose a single-phase 7.5KVA voltage stabilizer or a single-phase 10KVA voltage stabilizer.
