PURPOSE:The N-700 is an active electronic noise suppressor that employs a high density, low loss toroid 0.25 mH choke coupled with two power 2N3055 NPN power transistors in a capacitor multiplier configuration. The N-700 is designed to eliminate in-noise for Auto-sound Systems including: Alternator Whine, Fan Humming, ignition pops, etc.N-700 applications include Power Equalizers, Amplifiers, Cellular Phones, CB Radios, Two Way Communication Equipment, Amateur Radio Components, CD Players, and AM/FM Cassette Decks, etc.
FEATURES:The air cooled design of the N-700 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.The Beta of the power transistors multiples the capacitance to maximize the attenuation of the active filter. There are only three wires needed for the installation of the filter =Filter Input, Filter Output, and the Chassis Ground.The Chassis Ground is required to complete the circuit’s operation.
INSTALLATION:Make sure the noise is in-line before installing any in-line filter.A good confirmation would be to temporarily substitute a 120 VAC to a 12 VDC power supply, or a small 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-700, 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 of the cut (Source). If no fuse is present, be sure to add a fuse to this connection. Be sure to add a fuse rated at 10 Amps or less to protect the vehicle.
3.Connect the RED wire to the component side (Load). This output lead is also fused to protect the N-700.
4.Connect the BLACK wire to a good chassis ground.The N-700 will not function without a connection to chassis ground.
Practical and easy to install, the N-700 is one of the most versatile and effective filters on the market.
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.
THESE DEVICES ARE NOT FOR LIGHTNING PROTECTION AND PROVIDES NO PROTECTION FOR LIGHTNING STRIKES!!!!!
