Why it exists
When the supply drops to ninety volts, this is the unit that keeps the compressor alive.
Why it is built this way
Holds from 90 V. 80 V on inverter supply.
01
A genuinely wide window
Regulated output from 90 V to 290 V on fixed supply, and 80 V to 300 V on inverter supply. Most of the category gives up well before that.
02
Cut-off and AMP protection
Automatic cut-off outside the working window, with AMP protection against surge and overload.
03
Sized for the load
Eleven kilograms and 25 × 12 × 33 cm. This is a transformer specified for an air conditioner, not for a television.
