Abstract
In one aspect, a power connect device receives ac line voltage and provides ac load voltage to a load device. In one embodiment, the power connect device includes: a connect panel, a transformer circuit, a high voltage relay, a rectifier, and a voltage protection circuit. In one aspect, the transformer circuit includes first, second, and third transformers each with a primary winding, a high voltage secondary winding, and a low voltage secondary winding. In several embodiments, methods protect the load device from an over or under voltage conditions on the ac load voltage using the power connect device. The power connect device is reconfigurable for three phase and single phase operation. The power connect device is also reconfigurable for multiple line voltage levels.
