Power Distribution Hub Specifications

The following tables provide the operating and mechanical specifications for the Power Distribution Hub (PDH).

DO NOT exceed the maximum electrical specifications. Doing so will cause permanent damage to the Power Distribution Hub and will void the warranty.

The Power Distribution Hub's reverse polarity protection DOES NOT protect downstream devices. Verify the correct polarity on all power wires before operation.
