MAUX – Mecc Alte alternator Excitation System:
Mecc Alte alternator ECP and ECO series are equipped with
MAUX excitation system as standard.
The MAUX Mecc Alte Auxiliary Winding is a separate winding
within the main stators that feeds the regulator. This winding
enables every one of our alternators to take an overload of
300% forced current (short circuit maintenance) for 20 seconds.
This is ideal for motor starting requirements.

Performance Class:
According to IS0 8528, there are different performance cases associated with step load. These classes describe
requirements for different parameters that a genset should fulfil.
In the table below, is showed a resume of the most significant parameters defined in the ISO 8528-5:
Parameter G1 G2 G3
Steady State Frequency band
≤+/-2,5% ≤+/-1,5% ≤+/-0,5%
Steady State Voltage band ≤+/-5% ≤+/-2,5% ≤+/-1%
Frequency Recovery Time ≤10 s ≤5 s ≤3 s
Voltage Recovery Time ≤10 s ≤6 s ≤4 s
G1: Required for application where the connected loads only basic parameters of voltage and frequency need
to be specified. Typically required in general purpose applications, lighting.
G2: Required for application where voltage characteristics requirements are very similar to those for the
commercial public electrical utilities. Typically required in lighting systems, pumps.
G3: Required for application where the connected loads need high performance in terms of stability and level of
the frequency, voltage and waveform characteristics.
Typically required in Telecommunications applications.
G4: In this performance class frequency, voltage or waveform characteristics of the electrical power supply are
specifically adapted for the application. This performance is usually defined as an agreement between
manufacturer and customer (AMC).
Same genset can be compliant to different performance class, considering different step load %.
