Lima MAC AC Generator 12KW, Model 260MSL1055 SPECIFICATIONS12 kW (60 Hz)240V – 480V (60Hz)Designed specifically for starting three-phase AC electric motorsDelivers 1 HP/kW, Code G induction motor starting capability with 35% voltage dip (80°C rise rating).Self-excited and inherently voltage regulatedWith no external voltage regulator or transformers, it provides 4% voltage regulation, virtually maintenance-freeInherently provides 500% 3-phase short-circuit support and volts/hertz operationAvailable in one- and two-bearing designsRugged Construction Main and Exciter Rotor. Stator windings are Class F insulated with multiple dips and bakes of non-hygroscopic varnish for protection against harsh environments. Ratings are based upon NEMA Class B temperature rise for maximum generator life. Stator windings are a solid, moisture resistant type with superior physical and dielectric strength.Brushless Exciter. At the heart of the LIMA® MAC generator is a patented brushless excitation system. This excitation system is a 3 phase, rotating current transformer/frequency converter which responds to load changes and maintains output voltage within 4%. The 3 phase, full wave rectification provides a resulting low ripple (smoother) DC source to consistently excite the main field.Salient Pole Rotor Assembly. The LIMA® MAC main rotor utilizes a single piece, 4-pole lamination for maximum mechanical strength. Field windings are "wet wound" with enameled magnet wire in Class H thermosetting epoxy for high electrical integrity and designed to withstand overspeed of 125% of rated rpm for 15 minutes without damage.Permanently Lubricated Bearings. Bearings are single width, double shielded type ball bearings pre-lubricated for the life of the bearing and sized for a minimum B-10 life of 100,000 hours. Shafts are precision ground and the bearing carrier is cast iron with bearing outboard the exciter rotor.Cast Aluminum Alloy Ventilating Fan. Bi-directional high-efficiency fan and internal air flow patterns maximize heat transfer and minimize hot-spot differentials for longer winding life.Fully Guarded for Operator Safety. No exposed laminations or live parts. NEMA weather-protected Type 1 enclosure provides protection from environmental conditions and maximum operator safety. All LIMA® MAC generators are manufactured to applicable NEMA, IEEE, and CSA standards.Motor Starting Application Leader. LIMA® MAC generators provide field-proven motor application superiority on container refrigeration, center pivot irrigation systems, aggregate processing plants, sewage lift stations, and submersible pump applications. Additionally, they continue to be specified for general purpose power supply in rental fleets, on construction sites, and in light tower installations.LIMA® MAC industrial alternators are utilized worldwide whenever reliability, performance, and simplicity in design are required. Simple to install and operate.Freight Shipping or Free Local Pick up
