In case of amplifier faults, the central conductor is grounded forcing the equipment to enter stand-by mode. 7.4 Power Supply Block The power supply of the TEX302TFT provides the two main power supplies: 1. Services. This voltage powers elements that do not directly affect the power supply such as the motherboard, panel board and fans. 2. Power supply. This voltage powers the RF power amplifier module and protects the equipment from any sudden fluctuations in the mains voltage.
