LayerZero Power Systems, Inc. Power Distribution Unit Type-P

The Type-P design provides switching between two independent power sources on the primary side of two transformers providing dual power-path distribution capability. Prior to 2003, because of transformer inrush from out-of-phase transfers, you would have found the static switch on the secondary side of two transformers and you could only power the load by one or the other. But today, thanks to LayerZero’s Dynamic Phase Compensation Patent, the saturation current from out-of-phase transfers is minimized. Up to 24 subfeed circuit breakers are available.
