350KVA-2500KVA Marathon Generator MagnaMax Series Alternator

Advantages:

 1. Outstanding electric characteristic

Steady voltage regulation is less than 0.25%.

Transient voltage regulation is less than +20%, -15%(60%IN,P.F≤0.4lag).

Voltage adjusting range is over than 10% of Un.

Total voltage waveform distortion is less than 5%(L-L).

The steady short circuit is ≥300%In, and maintain time ≥10s.

It has wide stability range as using in non-linear load condition.

Good motor starting capacity.

Good paralleling performance.

2. Unique structure

Full guarded screen and louvers for operator safety. Unique ventilation and cooling may be efficient heat transfer and good windings cooling.

Brushless generator with PMG exciting system. It can provide 300% in safety short circuit current, and maintain time 10s. It has not the trouble of lost residue magnetism.

Salient unirotor construction. Rotor core closly coupled with die cast damping winding. The field windings are layer wound with thermo-setting epoxy for high mechanical and electrical integrity.

DVR2000E+ digital voltage regulator is encapsulated for reliable performance in varying environment such as protecting moisture and anti-vibration.

It’s voltage regulation has high accuracy about 0.25%. It include adjustable voltage, stability and volt/herz under speed protection, three phase RMS sensing, papalleling, over excition, over voltage protection and so on as standard.

End mounted conduit-box located at the rear of frame, It provides ample space to fit attachments and elements, and 4 bars may be connected easily to load.

H class insulation system.

Bearing is double shielded and pre-lubricated for long life.

Sae standard adaption.

Exciter, PMG and rectifier assembly loacted outboard of bearing for easy of inspection and maintenance.
