Hey,
Mods, I've posted this already on another website but I haven't got a satisfactory reply yet.
I've built a step down box to run 110 VAC appliances off incoming 240 VAC (Malaysia). The only components in the box are a cooling fan (240 V) and a great big transformer. It's a single phase 30A output aluminum wire 240V->110V 50 Hz transformer that weighs about 25 kg.
I think I need inductive kick protection for the transformer so that if the incoming 240 V is interrupted (by the upstream circuit breaker maybe), the inductive kick doesn't fry my 110 V equipment. I don't trust surge protecting power strips (and I can't get 110 V ones here anyway) so I'm looking for some discrete components I can use.
Does anyone have any experience with this? Would a MOV be suitable? Or a TVS?
Thanks for helping!
