Communications Equipment Interference Filter
Preventing switching spikes and noise generated by motors and other electrical equipment interfering with your communication and electronic equipment is an important part of any boat’s electrical system. JEC has developed a filter that will help prevent interference getting into your wiring.
The JEC EMI Filter is available in two models to filter 2 or 4 circuits.
The EMI Filter is housed in an aluminium cast box, hard anodised and powder coated for maximum protection. For cable entry, the specially designed nickel-plated brass glands provide watertight seals as well as electrically bonding any cable shield to the case.
Filters noises from various electronic DC equipment. Used on boat equipment, including electromagnetic clutches and motors with brushes to eliminate whining noises on HF radios.
