If you insist on using an AVR's 110V output, bear in mind that an AVR's VA rating is halved when using the 110V output, even exclusively. So a 2KVA AVR will only have an available 1KVA of output on it's 110V terminal.

Most important reason is that step-down transformers can handle/absorb the "start-up" current drawn by your power tools far far more than AVR's can. Consequently, it is the AVR that needs protecting against the power tool.

Salamat, coming from you they probably heed the advice better.



Ayos brader, just helping out... :thumbup:
