The AUDH-4000 from ACUPWR is a grounded step up/step down transformer that will convert voltage from 110-120V to 220-240V and from 220-240V to 110-120V. Rated for 4000W loads, this unit is a whole home transformer with knock out box housing. It does not come with a plug or output receptacle and is intended to be directly wired to a circuit breaker and thus power the entire home. Depending on how the unit is hard-wired, it will convert from 110-120V to 220-240V, and vice-versa.
The transformer unit includes copper wiring that allows it to operate under heavy duress, and in the most heavy-duty situations. It features thermal protection with automatic shutdown when overheated and automatic reset when cooled. This step up/step down, all-in-one whole home transformer/voltage converter can power your entire home, business, warehouse, even a small factory. Use it anywhere that uses the 110-120 and 220-240 voltage standards.
