Electro Magnetic Interference (EMI) is a natural byproduct of all aviation anti-collision strobe systems, both old and new. It is created and radiated when strobe systems suddenly turn electricity into light pulses, and sometimes can be annoyingly detected in intercoms and communication radios as audio noise every time the strobes activate. Aveo Engineering designs and builds extremely quiet LED strobe systems, as evidenced by our beacons and wingtip units. So much so that Aveo products are widely used in military UAVs, where low EMI is an absolute requirement. Anything that could interfere with operational telemetry is simply not tolerated. In aviation, there is no such thing as good EMI, no matter how small. Aveo has taken the extra step to create the Super Spike-SD series of in-line EMI filters. These small, inexpensive units are extremely effective in greatly attenuating residual EMI found in avionics installations. Spectrum analyzer photos which can be viewed on the Aveo website: https://www.aveoengineering.com/spike-sd/ show just how effective the Spike-SD filters are. (Frequency range of the analyzer photos depicted is 300kHz – 2MHz, which corresponds to DO-160 Chapter 21, Emission of Radio Frequency Energy.)
IMPORTANT NOTE: Hercules Drop-In with the lower voltage range of 9-18VDC has only one input and cannot be used with super Spike-SD, as current consumption is 12.6A at 9VDC, which exceeds 8A per channel. Samson Drop-In also has only one input and cannot be used with super Spike-SD, as current consumption is 11.1A at 18VDC, which exceeds 8A per channel. |
