MARELLIMOTORI AVR M25FA645A ELECTRONIC VOLTAGE REGULATOR
The MARELLIMOTORI AVR M25FA645A voltage regulator technologically advanced and extremely reliable with very compact dimensions and low costs.
The MARELLIMOTORI AVR M25FA645A an electronic device mounted on the alternators, which automatically adjusts the output voltage as the load varies. The electronic voltage regulator is mainly used to make the voltage stable and the current clean, thus avoiding sudden changes in voltage that can damage sensitive devices such as PCs, smartphones or connected appliances. The main and most common voltage regulators are the AVR and the inverter are modern, but in some alternators or generator sets there are also capacitor or compound regulators.
It includes low speed protections; and overload protection with adjustable tripping threshold, 50/60 Hz operation, adjustable droop and the possibility of overloading. to adjust the voltage remotely.
