TX12.5KSS PLUG-IN NEXT GENERATION
COD. TX12.5KSS/60D41/EPS
Potencia: 12.500W
12.500W PLUG-IN Next Gen System.
FEATURES
• Tunable over entire FM band (87.5 – 108 MHZ), without tuning.
• Overall efficiency better than 71-73%.
• Hot-pluggable and broadband power amplifier modules.
• High redundancy guaranteed.
• Each amplifier module provides Automatic Power Control.
• Each module has its own hot plug-in fans set.
• 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.
• 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.
EPS:
• Each power supply “PS" can be removed or plugged without turning off the transmitter.
• The transmitter is capable of generating an output power with ample margin thanks to oversized power supplies.
• By installing an additional PS, the transmitter will operate at full power in the event of a single PS failure, eliminating the need for derating.
• Each PS features an automatic magnetic switch preventing short circuits and ensuring uninterrupted signal broadcasting.
• The power stream generated by these PS are distributed in parallel to all RF modules; consequently if one
power supply fails all RF modules maintain balanced operation.
• The transmitter’s CCU oversee continuously the operational status of each individual power supply.
• In the event of a failure the "ECM" electronic control module will optimize the transmitter efficiency.
• In an empty slot an additional power supply can be turned on so in the
event of a power supply failure there will be no reduction in power. It is a N+1 PLS system . Only from 4 to 10kW(option)
