Power is rated at 300 Watts for the 24 Volt circuit and 120 Watts for the 12 Volt circuit. This is the total output of the internal DC/DC converters and is divided across all connections as demanded by each externally connected device. Each connector pin is rated to 5 Amps, which should not be exceeded. For any one connector, the maximum Watts should not exceed 120 Watts for the 24 Volt circuit and 60 Watts for the 12 Volt circuit.
