3 kVA Home Voltage Stabilizer, Single Phase, 110V~240V

Note: The provided 3 kVA voltage stabilizer is 1-phase (L, N, G) by Europe standard. And we can customize the split phase (L1, L2 + G) like the USA standard, just confirm with us by email after ordering.

Q1: Which home appliances can this 3kVA stabilizer protect?

This 3kVA stabilizer is ideal for a wide range of medium-power home appliances, including 1.5-ton air conditioners, refrigerators, LED/LCD televisions, home theater systems, desktop computers, water pumps, and microwave ovens. It is recommended to check the wattage of your devices to ensure the total does not exceed the stabilizer's 3000VA (or ~2400W) capacity for optimal protection.

Q2: What happens when the voltage is too low or too high?

The stabilizer's intelligent CPU constantly monitors the input. If the mains voltage drops below 140V or surges above 260V, which is beyond its correction range, the unit will automatically and immediately cut off the power supply to your connected appliances. This critical safety feature prevents damage from severe under-voltage or over-voltage conditions. Power is automatically restored once the mains voltage returns to within the 140V-260V operating range.

Q3: What is the purpose of the output delay function?

The output delay (typically 3-5 seconds) is a protective feature that prevents a high-power surge from reaching your appliances immediately after a power cut is restored. This delay allows the mains voltage to stabilize first, thereby protecting compressor-based appliances like refrigerators and air conditioners from the stress of sudden high-current startups, which can extend their lifespan.
