How To Correctly Select An Automatic Voltage Stabilizer That Meets The Power Of The Equipment

Before buying Automatic Voltage Regulator, many customers only know that they need to use it, but when they actually buy it, they don’t know how much power they need to match the automatic voltage stabilizer. They buy a high-power one but don’t actually need that much power, which will cause waste; if they buy a lower power one, the automatic voltage stabilizer is often fully loaded or even overloaded, which will cause the automatic voltage stabilizer to be frequently damaged and burned, resulting in an invisible increase in cost; they spend a lot of money but can’t buy the automatic voltage stabilizer that suits them.
1. Power matching principle: because load equipment can be divided into three categories in reality: pure resistive load, curvilinear load (inductive or capacitive), and nonlinear load. The output power of the original equipment in the general industry is measured by pure resistive load, and the three intrinsic power factors of pure resistive load, linear load, and nonlinear load are different, and even far apart. The power factor of pure resistive load is 1; the power factor of linear load is usually 0.6-0.8, and the power factor of nonlinear load is usually regarded as 0.2-0.4. Therefore, the maximum power that power products with the same power can match for different types of loads is different! Take the automatic voltage stabilizer as an example: the automatic voltage stabilizer can carry a maximum of 8KW pure resistance load, but it can only carry a maximum of 5KW with a curve load or a non-linear load of only 3KW.
2. The equipment cannot be operated at full load for a long time, and a certain margin must be left in the power matching ratio. For example: a 10KVA UPS (output power factor 0.8) can carry a maximum load of 8KW, but a load of 8KW is already running at 100% full load. It is okay to occasionally have such a situation in daily life, but long-term full-load operation will have a great impact on the operating life of the automatic voltage stabilizer, and the probability of failure will also be greatly increased. Therefore, it is more appropriate to keep a 30% margin for the equipment load rate, that is, the best load rate of the automatic voltage stabilizer (output power factor 0.8) should be: 10KVA×0.8×70%=5.6KW or less, that is, keep a 30% margin on the basis of the full load 10KVA×0.8=8KW! Only in this way can the long-term operation life of the machine be greatly extended.
