Proven top performers in every respect, Marathon MagnaPLUS® generators offer powerful performance, reliable power generation, and easy installation. With a full range of voltage regulator configurations, MagnaPLUS® provides application flexibility to meet unique installation requirements. Ruggedly constructed with solid state technology, Marathon’s SE350 voltage regulator, included with all standard equipment, is a solid performer.
- Choice abounds with more than 34 stock models ranging from 5–420 kVA (50 Hz). All three-phase generators are 12-lead reconnectable, providing voltage and phase flexibility. For applications requiring pricesensible, dedicated single-phase generators, Marathon Electric stocks 26 models. Standard and optional conduit box designs are available to meet all customer requirements and to ease installation of accessories.
- Easy Mount SAE Adapters provided with every generator, are designed with easy drive disc access to simplify the mounting to all popular engines. Generator foot mounting location is unaffected by adapter changes. Special adaptations for automotive engines are available.
- Class H Insulation System utilizes an unsaturated polyester varnish for optimal insulation life and superior moisture protection. An epoxy overcoat is added for increased environmental protection. Field windings are wet wound with epoxy and designed to withstand overspeeds of 125%. All windings are 100% copper with class H insulation.
- Linkboards are standard to simplify voltage reconnection and support lead termination
- SE350 Voltage Regulator is encapsulated for reliable performance in all environments. The SE350 regulator provides 1% regulation, underspeed protection, stability adjustment to optimise transient performance, and EMI filtering to commercial standards.
- Optimised Electrical Design with fourpole, brushless features, utilizes a 2/3 pitch winding to minimize harmonic distortion. The main rotor, utilizing Marathon Electric’s unirotor construction, provides exceptional waveshape and voltage balance. The unirotor construction method incorporates full amortisseur windings facilitating parallel operation and non-linear loads.
- Enhanced Ventilation created by a high efficiency cast aluminum fan and optimized internal air flow patterns, maximizes heat transfer and minimizes hot spot differentials for extended winding life. Durable aluminium alloy fans avoid breakage problems associated with steel weldments or plastic fans.
- Fully Guarded for operator safety and generator protection. No rotating or electrically energized parts are exposed. All openings are covered by louvres or screens.
- Heavy Duty Bearings are double shielded and pre-lubricated for the life of the bearing. This helps resist contamination and ensures a maximum bearing life.
- Design Specs and Agency Approvals are important at Marathon. All MagnaPLUS® units meet NEMA MG1-32, BS5000, and IEC 34-1 requirements. MagnaPLUS® generators are also CE Certified, CSA Certified and fully UL Listed. Marine versions are available to meet American Bureau of Shipping, Lloyds, Det Norske Veritas, or Nippon Kaiji Kyokai requirements.
