System Overview: The drive input is directed to an internal 16-way splitter, providing the PA module input drive. Each E2021 Power amplifier features dual packaged MOSFETs mounted on a substantial heatsink assembly, optimizing airflow over RF components. DC power is supplied to the RF modules from 8 switched mode power supplies. Individual E2021 power amplifier modules incorporate internal control and self-protection mechanisms, such as reverse power, excess current, or over-temperature conditions. All monitoring data is microprocessor-derived. Each module transmits its internal parameters to the central transmitter controller/monitor (E2023), and you can conveniently view these parameters on an easy-to-read backlit LCD screen.
Cooling Systems: The S7605C transmitter features self-contained redundant cooling fans mounted on the rear of the transmitter. For specialized requirements, the cooling system can be ducted, and bespoke systems are available.
