PURPOSE:The N-25 is a passive noise suppressor that employs a high density, low loss toroid 0.25mH choke designed to eliminate in-line noise for Auto-sound, Avionics, and ham radio/CB/Two-Way communication systems including: Alternator Whine, Fan Hums, Dodge Ram Cummings Torque Converter Clutch Cycling Repair*, etc.The N-25 applications include Power Equalizers, Small Amplifiers, Cellular Phones, CB Radios, Two Way Communication Equipment, CD Players, and AM/FM Cassette Decks, etc.
FEATURES:The air-cooled design of the N-25 filter permits maximum efficiency and effectiveness.The ferrite toroid core of the choke component of the L configuration is responsible for a very high rate of attenuation with very low line losses.There are only three wires needed for the installation of the passive filter -Filter Input, Filter Output, and the Chassis Ground.
INSTALLATION:Make sure the noise is in-line before installing an in-line filter such as the N-25.A good confirmation would be to temporarily substitute a 120 VAC to a 12 VDC power supply, or a 12 Volt motorcycle battery, for the vehicle's electrical system.If the noise goes away when the alternate power supply is connected, then you have a case of in-line noise.
To get optimum results with the N-25, the following directions should be followed:
1.Cut the component's main power lead between the fuse and the component.
2. Connect the Green wire to the fuse side. (If there is no fuse, add one --- 10 Amps is recommended)
3.Connect the fused Red wire to the component side.
4.Connect the Black wire to a good chassis ground.
Practical and easy to install, the N-25 is one of the most versatile and effective filters on the market.
Note: The 30-Amp rating is instantaneous = peak… not constant. Fuse the Green lead with a 5 to 10-Amp fuse. Average current draw should be no larger than the fuse size of 10 amps.
Due to many requests for antenna static bleeders, we have developed a product line of static bleeders for coax and for ladder line applications. Static electricity is caused by many situations including high desert wind, atmospheric conditions, etc. You may hear static crashes or have a buildup of static electricity that my be annoying during a radio conversation and it may be harmful to solid state electronics if high voltages are present on the RF input to your equipment.
A static “Bleeder” which shorts the direct static voltage to ground while leaving the RF frequency voltage unaffected if very beneficial particularly to those operations in desert conditions where low humidity, high static buildup are quite common. The SB-1 and SB-2 coax static bleeders work on coax line and the SB-3 static bleeder is meant for ladder line.
