Transmitter AC-Powered Heat Sink

The heat sink assembly includes an integral +12 VDC fan and a power supply transformer. Use for TIMTER™, Dual TIMTER™, and nanoTX™ transmitter testing at the bench; not airborne approved.

Part Number: QSX-AC-32-HS-12V
(formerly QSX-TIMTER-HS-12V)

Thermal Considerations

It is important that the transmitter’s bottom surface (on the face opposite the product label) be securely attached to a baseplate capable of dissipating the power produced by the transmitter model in use. This mounting baseplate must be flat, smooth, and clean.

ATTENTION: You must operate the transmitter with a proper heat sink. Failure to do so may lead to permanent damage to the unit and will void the warranty. Overheating can occur in a matter of seconds when a transmitter is not properly heat-sinked. In absolutely no case should any type of stickers or labels be applied to the bottom surface of the transmitter.

The heat sink required for a particular transmitter depends heavily on the installation. Factors such as altitude, air temperature, air flow, and mass of the mounting surface all have a substantial impact on the flow of heat away from the transmitter. Quasonix offers several types of integrated and add-on heat sinks. Please contact support@quasonix.com for the power dissipation required and heat sink recommendations for your particular TIMTER™ transmitter.

Regardless of the heat sink, Quasonix strongly suggests using a thermal pad, such as Q-Pad® II from Bergquist.

    • Michael,

      My guess (without any verification) is that the unit will run down to -34°C – if it’s already running as the temperature is lowered. It probably will not start at -34°C.

      The airborne heat sink will meet your need.

      Best Regards,
      Terry
