VA (Volt-Ampere) is the unit of apparent power. In this case, 650VA indicates the load capacity the AVS can handle.

Question 22

What appliances can a 650VA AVS support?

Accepted Answer

It is suitable for TVs, refrigerators (single door), home routers, decoders, fans, and other small electronics.

Question 23

Does a 650VA AVS protect against high voltage?

Accepted Answer

Yes, it automatically disconnects appliances when voltage goes beyond safe limits.

Question 24

Can it protect against low voltage?

Accepted Answer

Yes, it cuts off supply during under-voltage and restores only when power stabilizes.

Question 25

Is 650VA enough for a refrigerator?

Accepted Answer

Yes, it can support a single-door refrigerator or small-sized fridge efficiently.

Question 26

Does a 650VA AVS have a delay feature?
