Application guide:  


In a piston engine aircraft, the voltage regulator is an electrical component that is responsible for regulating the electrical power output of the aircraft’s alternator or generator. The voltage regulator helps to maintain a consistent voltage level within the electrical system, which is necessary for proper operation of the aircraft’s avionics, lights, and other electrical equipment.

The voltage regulator works by monitoring the electrical output of the alternator or generator and adjusting the output voltage as needed to maintain a stable voltage level. This is important because electrical equipment is designed to operate within a specific voltage range, and fluctuations in voltage can cause damage or malfunction.

Most aircraft voltage regulators are designed to maintain a voltage output of around 14 volts DC, although the exact voltage level may vary depending on the specific aircraft and electrical system.

There are several different types of voltage regulators available for aircraft, including mechanical and solid-state designs. Mechanical regulators use a set of contacts and a bimetallic strip to regulate the voltage, while solid-state regulators use electronic components to control the voltage output.

In addition to regulating voltage, some voltage regulators may also include other features such as overvoltage protection, which helps to prevent damage to the electrical system in the event of a voltage spike, and voltage monitoring, which allows the pilot to monitor the voltage output in real-time.
