Description

The Eddystone S79005 500W Transmitter/Amplifier embodies the renowned modularity and efficiency for which Eddystone is known, packed into a compact and cost-effective package. Here’s a detailed breakdown of its features and specifications:

Features:

  1. Modular Design: Utilizes E2021 300W hot-pluggable Power Amplifier modules, enabling the removal of amplifiers with minimal reduction in output power. Retains complete compatibility with its predecessor, the S7600 series amplifiers.
  2. Compact and Replaceable Modules: Both Amplifier and PSU modules are replaceable on air, facilitating maintenance without disrupting broadcasting.
  3. Compliance: Fully compliant with the ETS 300 384 specification for FM transmitters, ensuring adherence to industry standards.
  4. System Flexibility: Easily configured into various system architectures to suit different operational requirements.
  5. Efficient Power Management: Employs highly efficient SMPSU power supplies with power factor correction (PFC), optimizing energy usage.
  6. Remote Control and Monitoring: Offers comprehensive remote control and monitoring facilities for efficient management and supervision of transmitter operation.
  7. User-Friendly Interface: Features an LCD display for easy local monitoring, ensuring clear visibility of system parameters and status.

System Overview:

  • Drive Input: Fed to an internal 2-way splitter, providing the PA module input drive.
  • Power Amplifier Modules (E2021): Each module utilizes dual-packaged MOSFETs mounted on substantial heatsink assemblies with minimal airflow over RF components. Internal control and self-protection mechanisms ensure safe operation.
  • Central Transmitter Controller/Monitor (E2023): Receives and displays internal parameters from individual power amplifier modules, enabling centralized monitoring and control.
  • RF Output Combining: Outputs from the 2 power modules are combined via a highly efficient 2-way common rail Wilkinson combiner, ensuring optimal RF output.

Cooling:

  • Equipped with self-contained redundant cooling fans mounted on the rear of the transmitter. Ducting options are available, and bespoke cooling systems can be provided to meet specific requirements.

Specifications:

  • Power Output: 500W (adjustable to -6dB)
  • Operating Frequency: 87.5 to 108 MHz
  • RF Output Load Impedance: 50 ohms unbalanced
  • RF Output Connector: N Type Female
  • Maximum VSWR: Able to maintain full power at 1.5:1 before protection cuts in
  • Mains Power Supply: Single phase 85-265V
  • RF Harmonic Output: Better than or equal to -79dBc
  • Ambient Temperature Range: 5 °C to +55 °C at an altitude up to 3000M
  • Overall Efficiency: Typically 60%

This transmitter/amplifier combination offers a reliable, efficient, and cost-effective solution for FM broadcasting, suitable for various professional broadcasting environments.
