Aircraft Voltage Regulator Wiring

Most aircraft voltage regulators used today are.

Aircraft voltage regulator wiring. The voltage regulator continuously monitors the bus voltage and adjusts the output of the alternator. Simplicity 700 725 b1 garden mark wiring made simple. Where you ll find answers to many of your questions about aircraft alternators and voltage regulators. Vibrating point voltage regulator for generators duration.

Aircraft alternators are externally regulated by a voltage regulator sometimes called an alternator controller which is usually mounted either on the firewall in the engine compartment or under the instrument panel. After testing and acceptance of the alternator if the problem with the charging system still hasn t been found look at the voltage regulator next. Aircraft wiring usually consists of tin coated copper stranded wire covered by insulation. Most aircraft voltage regulators used today are solid state and no longer have the trouble prone contact points and coils.

Until the early 90 s wire was insulated with pvc but it has since been phased out and replaced with tefzel. Some wires are also reinforced with nylon. The regulator works when it is powered from a bus through a wire called the field wire. The alternator provides power to electrical devices like lights and avionics and also charges the aircraft battery.

The job of the voltage regulator is to adjust the field current so the alternator output is at a constant voltage nominally 28 25v. Providing standard products such as voltage regulators and monitors as well master control units lamar is combining innovative thinking with precision quality. The plane power brand delivers aircraft alternators with outstanding performance value and installation flexibility. Oem wiring is usually coded about every six to twelve inches.

This regulator has only three wires a common configuration. Voltage regulator installed on the firewall of a cessna. As such regulator problems other than basic adjustments are minimal. Lamar quality products are well known in the general aviation industry and are installed on over eighty five percent of existing single and twin engine piston and turbine aircraft.
