Voltage V: 400
Frequency Hz: 50
Power factor cos Ï•: 0.8
Poles: 4
Type: Brushless
Voltage regulation system: Electronic
Standard AVR: DSR

Mechanical structure:
Robust mechanical structure which permits easy access to the connections and
components during routine maintenance check-ups.
Voltage regulator: Voltage regulation with DSR. The digital DSR controls the range of voltage, avoiding any possible trouble that can be made by unskilled personnel. The voltage accuracy is ±1% in static condition with any power factor and with speed variation between 5% and +30% with reference to the rated speed.
Windings / Excitation system
Generator stator is wound to 2/3 pitch. This eliminates triplen (3rd, 9th, 15th …)
harmonics on the voltage waveform and is found to be the optimum design for troublefree supply of non-linear loads. The 2/3 pitch design avoids excessive neutral currentssometimes seen with higher winding pitches. MAUX (Standard): The MAUX MeccAlte Auxiliary Winding is a separate winding within the main stators that feeds the regulator. This winding enables to take an overload of 300% forced current (short circuit maintenance) for 20 seconds. This is ideal for motor starting requirements.
Insulation / Impregnation
Insulation is of class H standard. Impregnation is made with premium tropicalised
epoxy resins by dipping and dripping. High voltage parts are impregnated by vacuum, so the insulation level is always very good. In the high-power models, the stator windings undergo a second insulation process. Grey protection is applied on the main and exciter stator to give enhanced protection.
