Inherent to the MAGNAMAX design is exceptional transient performance, enabling it to support a variety of non-linear loads, such as UPS systems or variable speed drives. It delivers unprecedented voltage regulation, and its low-reactance design minimizes distortion.
MagnaMax features Marathon’s exclusive Unirotor construction, meaning that the main rotating field consists of a single diecast unit. Cast aluminum fills the damper bar holes, eliminating the need for welding or pins and ensuring greater rotor durability.
Combined with UL-recognized class H insulation system and long-life bearings, this rugged construction ensures the reliability needed for emergency standby power and the longevity for prime power applications.
The MAGNAMAX is the ideal alternator for voltage-critical applications such as:
Telecommunication Networks
Hospitals
Computer Centers
Commercial Buildings
Airports
