Power Supply and Protection
In order to provide power to this redundant, hot standby radio system, the QH supports dual power supplies. A separate power
supply is used for each of the full duplex radios. To help increase reliability, the power supplies are crossed-over to each of the
secondary supply inputs of the full duplex radios as shown in the diagram below.
Each full duplex radio has diode-ORed supply inputs, making a redundant power supply pair for each full duplex radio possible.
The Hot Standby Controller has connections for dual power supplies and is powered from the 12V DC output of the full duplex
radios as shown in the diagram below.
