SVC high-power household 220V fully automatic AC voltage stabilizer 500W voltage stabilizer TND
The TND voltage regulator is a single-phase fully automatic AC voltage regulator with prominent advantages: it features high voltage regulation accuracy (within ±4%), a wide input voltage adaptation range (e.g., 110-250V), comprehensive protection against overvoltage and undervoltage, as well as diverse configurations such as air cooling/self-cooling and LED/pointer display, along with fast respon

Precautions
The following products are not suitable for voltage stabilizers:
Voltage stabilizers are not suitable for marine electrical appliances.
Reason: The voltage and frequency generated by marine generators fluctuate greatly. This situation will damage the voltage stabilizer and easily burn it out.
Voltage stabilizers are not suitable for electrical appliances of the single-phase asynchronous motor type.
Electrical appliances with single-phase asynchronous motors include: water pumps, air compressors, mixers, lawn mowers, etc. For specific reasons, please consult customer service. Reason: The starting inrush current of single-phase asynchronous motors is very large. Generally, the wire diameter of civil single-phase power incoming lines is limited and cannot withstand large current impacts, and the voltage will drop sharply instantly.
Voltage stabilizers are not suitable for occasions where the distance from the power transformer line is very far and the voltage drops sharply.
Reason: If the distance from the transformer exceeds 1km, the line loss is very large, and the voltage will also drop sharply instantly. The voltage stabilizer cannot respond at all, and the instantaneous voltage cannot be stabilized by the voltage stabilizer.
The following situations require selecting a voltage stabilizer with a model enlarged by 5 times:
Electrical appliances of the switching power supply type must be selected with an enlarged model because such appliances belong to ultra-capacitive loads and have a relatively low power factor during operation. If the voltage stabilizer is improperly selected, it is very easy to cause damage to or even burn out the voltage stabilizer. (For example: equipment such as monitoring devices, electric vehicle charging devices, audio power amplifiers, and products with switching power supplies such as DC power supplies)
