THRANE & THRANE TT-6090A SAILOR 6090 POWER CONVERTER 21-32V DC 406090A 2011/35

Thrane & Thrane SAILOR TT-6090A Power Converter (406090A)

The SAILOR TT-6090A is a robust, DC-to-DC power converter designed specifically for the demanding environment of maritime and land mobile applications. Its primary function is to provide stable and protected power to critical Thrane & Thrane (now Cobham SATCOM) communication equipment, most notably the renowned SAILOR FleetBroadband satellite terminals.

As a vital component in the system’s power chain, it ensures that sensitive satellite communication hardware receives clean, consistent voltage regardless of fluctuations in the vessel’s main power supply.

Key Features & Functions:

1. Wide-Range DC Input: Accepts a broad input voltage range of 21-32V DC. This covers standard nominal shipboard voltages (24V DC) and provides tolerance for voltage drops and surges common in marine electrical systems.
2. Stabilized Output: Converts the variable input to a precise and clean +28V DC output required by the connected radio terminal (e.g., SAILOR 600, 500, or 250 FleetBroadband systems).
3. High-Efficiency Design: Engineered for minimal power loss, reducing heat generation and saving energy, which is crucial for always-on systems.
4. Comprehensive Protection:
   • Input Reverse Polarity Protection: Safeguards the unit and connected equipment from damage if power cables are incorrectly connected.
   • Input Over-Voltage Protection: Protects against spikes and surges in the ship’s power.
   • Output Over-Current & Short-Circuit Protection: Automatically limits current to prevent damage from faults in the connected load.
5. Robust Maritime Construction: Built to withstand the harsh conditions at sea, including humidity, salt spray, and vibration. Typically features a durable metal casing.
6. Plug-and-Play Integration: Designed as a direct, compatible power source for specific SAILOR terminals, using proprietary connectors for simple and reliable installation.
7. Compliance: The marking “2011/35” indicates compliance with EU marine equipment directives, confirming it is approved for use on ships registered in the European Union.

Technical Specifications :

• Manufacturer: Thrane & Thrane (now part of Cobham SATCOM).
• Model: TT-6090A / 406090A (SAILOR 6090).
• Input: 21 – 32 V DC.
• Output: +28 V DC.
• Application: Primary power supply for SAILOR FleetBroadband satellite communication terminals.

Typical Use Case:

On a vessel with a 24V DC main power system, the TT-6090A is installed between the ship’s switchboard and the SAILOR FleetBroadband terminal. It ensures that the satellite terminal receives a perfect 28V DC, even if the ship’s voltage fluctuates due to engine starts, generator changes, or other loads. This stability is essential for reliable, uninterrupted broadband communication at sea.
