This high-quality 10 AMP suppression filter puts an end to interference noises caused by the on-board electrical system, such as alternator and switching noises.
The interference suppression filter is connected to the 12V power supply line, as close as possible to the consumer.
Suitable for car radios, amplifiers, equalizers, CB radios, mobile phones, etc.
In which cases to use:
1) A screeching whistle through the radio/amplifier, varying in pitch with engine speed.
2) A ticking sound in the radio/amplifier that varies with the engine speed, frequency usually 1/4 of the engine speed.
Remark:
If the engine is off and the fault is present, there is no point in using this interference filter.
Connection:
Red wire on the +12V to be suppressed
Black wire to ground (-12V)
Blue wire is +12V for the consumer (car radio, amplifier...)
