FAQ

1.What is rated power?

Rated power refers to rated output capacity of transformer under rated working conditions (equal to U*I, unit is kVA).

2.What is rated voltage?

Rated voltage refers to no load, rated sub-voltage, the value of the end voltage (i.e., the primary and secondary side voltage).

3.What is No-load loss?

No-load loss refers to the loss of the transformer (also known as iron loss) under no-load conditions.
