Power Supply
The QH has facilities for dual power supplies to provide for a redundant system. A separate power supply should be used for each
of the full duplex radios, then to help increase reliability, cross-over the power supplies to each of the secondary supply inputs of
the full duplex radios shown in the diagram below.
Each full duplex radio has diode-ORed supply inputs, so a redundant power supply pair for each full duplex radio is also possible.
The Hot Standby Controller has connections for dual power supplies and should be powered from the 12V DC output of the full
duplex radios as shown in the diagram below.
