TTD Series – MEDIUM POWER Transmitters – AIR Cooling 2022-06-02T12:40:12+00:00

Project Description


  • Air cooling
  • Hot-plug Modules
  • High Efficiency Doherty.
  • All bands: BI, BIII, UHF
  • All standards : DVB-T / T2, ISDB-T / Tb, ATSC / ATSC 3.0, PAL / NTSC, possibility of Dual-Cast Analogue/Digital

BTESA design has many standout features:

  • Excellent design of air cooling system
    • 6 fans per amplifier module: if one fails, the module will continue working at full power
    • Anti-condensation system which prevents production of water drops inside the rack
    • Ducted air system for higher efficiency: avoids the need to use Air conditioning. Closed Rack with cold air input fans and hot air extractors
  • Electrical system Protections
    • Large mains input voltage range (± 20%)
    • Robust TVSS protections at transmitter input and also at each amplifier input:
    • Power factor > 0.95.
    • Option for full redundancy of Power supplies at each amplifier
  • Logic control unit Protections
    • Hardware backup for the logic control, so that the logic control unit can be removed even in operation and the transmitter will continue working safely thanks to the hardware protections.
  • High Efficiency
    • Wide band or narrow band Doherty
    • Fans with temperature controlled speed
  • Local and remote monitoring
    • Colour Touch-Screen and event log.
    • Remote monitoring and control though webserver or SNMP
  • Easy maintenance
    • Easy access to all components.
    • BTESA designs and manufactures all the circuits and modules of its transmitters, and therefore can guarantee the availability of spare parts through the lifetime of the equipment.
