TX04KSS PLUG-IN NEXT GENERATION
COD. TX04KSS-60D44/EPS
Potencia: 4.000W
4.000W 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)
