Review HARTZELL Alternator New

The Hartzell ES-4001 is a reliable and efficient alternator designed for aviation applications. This alternator is specifically engineered to meet the power requirements of light aircraft, providing a continuous output of 40 amps at 28 volts. The ES-4001 is a three-phase alternator, which means it generates a three-phase electrical output that can be converted into single-phase power for use in most avionics systems.

The alternator is constructed with a robust and durable design, featuring a cast aluminum housing that provides excellent heat dissipation and protection from the rigors of flight. The alternator rotor is made from high-strength copper wire, ensuring optimal electrical conductivity and long-lasting performance. The rotor is also equipped with a set of precision-balanced, glass-filled nylon bearings that minimize vibration and ensure smooth operation.

The ES-4001 alternator is also equipped with a number of features that make it easy to install and maintain. These include a built-in voltage regulator that maintains a consistent output voltage, even under varying load conditions. The alternator also features a diode rectifier that converts the three-phase alternating current to direct current for charging the aircraft battery.

The Hartzell ES-4001 alternator is designed to meet the strictest aviation standards, including FAA TSO-121 and EASA ETSO-3. It is also backed by a comprehensive warranty that covers defects in materials and workmanship for a period of 12 months from the date of purchase. Whether you're flying cross-country or just taking a short hop, the Hartzell ES-4001 alternator is the ideal choice for providing the power you need to keep your aircraft flying safely and efficiently.
