Tunable over entire band (87.5 – 108 MHZ), without tuning. (MONO RACK)
The image of this layout is purely demonstrative and may change without notice. The configuration is only referred to installed equipment; rack, cover panels and all others accessories are to be defined at order.
Features
> Tunable over entire FM band (87.5 – 108 MHZ), without tuning.
> Overall efficiency better than 70%.
> Hot-pluggable and broadband power amplifier modules.
> Each module features switching mode power supply to control and stabilize power supply voltage.
> Each amplifier module provides Automatic Power Control.
> Suitable for mono & stereo broadcast operations.
> Protection against high VSWR, overdrive, overcurrent and overtemperature.
> Compliance to IEC safety standards.
> Compliance to ETSI – CCIR – FCC standards.
> Entire transmitter can be switched off through an emergency button.
> High redundancy guaranteed by 10 power modules of 2.2 kW RF power.
> All measurement and working parameters are displayed on front panel.
> Remotely controllable by telemetry system.
> Design for 24/7 non-stop operation.
> The transmitter include an integrated system for automatic and manual switching between two exciters. In Automatic mode the changeover is activated when active power of exciter falls below 3dB.
