D Over-voltage shutdown: Limits voltage if output terminal becomes disconnected from the battery. Open-sense shutdown: Shuts down alternator if sense terminal goes open. Load-dump protection: Protects the transistor from transient voltage spikes. Regulator Stator Delivers absolute consistency; 100% tested – Guarantees dependability; Polyester heavy-coat wire. Ensures regular coating for electrical reliability, quality performance, rated 180°C. Rotor Rotor shafts are CNC-machined and precisionground for precise proportions and a smooth finish. Splines and bearing exteriors are heat-treated. Wire and varnish rated 1800C. Field Coil Rectifier Bearing Field Coil has been separated from the rotor; thus, brushes have been eliminated, creating more durability and consistency. Rectifier: It rectifies current from AC to BC. Fan Extracts heat and keeps the alternator cool. CTP Bearings are made with top quality seals to extract grease pollution and leakage. • Bearings use performance grease. • Protection from excessive temperatures from -40°F up to 392°F (-40°C to 200°C) • Load-dissipating thickness guarantees long service lifespan and protects it against thermal and motorized shock. In order to deliver a dependable and quality performance, CTP Alternators ensure wear resistance and trustworthiness due to top-notch technology Part No. 6N9294
