The GREEN RF™ technology, combined with the new 65:1 devices, is the latest evolution of the world-famous patented COLD-FET™ technology:
- High RF efficiency (>70%).
- Higher safety.
- Higher reliability.
- Lower heating.
- Lower AC power consumption.
Hot-Plug Solution (optional)
All FM amplifiers KFG series over 5kW can be equipped optionally with the hotplug system to instantly extract the amplifier modules with amplifier in full power. All the amplifier modules slide on telescopic rails and can be completely extracted and removed for on-air maintenance or replacement without disconnecting any cable and without interrupting the transmitter operation.
An intelligent protection circuit reduces the output power without on-air interruption, keeping the RF devices always within the safe operating parameters in case of:
- Load mismatching.
- Environmental over-temperature.
- Cooling failure.
- Failure in one or more amplification modules.
- Failure in power supply modules.
High efficiency cooling system
The air cooling system limits the heat-sink temperature rise to only about 10°C above ambient temperature. This guarantees the properly functioning even at high temperatures and in sites with extreme climate conditions.
Hot Swappable Power Supply Units: It makes easier the serviceability and the maintenance. Their tool-less and instant installation from front panel make the PFG NEXT transmitters ideal for critical environment systems where no down time can be tolerated.
Automatic Current Sharing (ACS): the automatic current balancing system is present on each unit to grant a perfect load distribution and very best power supply operating conditions.
