Prestolite AC172RA Series Heavy-Duty Alternator Export Product Introduction

Radial ribbed red fan housing strengthens axial airflow, rapidly dissipates heat from stator coils and rectifier diodes, avoids overheating burnout under long-term high-load power generation for vehicle air conditioners and electrical appliances.

High-purity enameled copper wire winding, low internal resistance, stable voltage output, strong overload capacity, effectively solves the problem of insufficient battery charging during idling of large buses and heavy trucks.

Exposed hexagonal rectifier terminal layout, convenient for circuit inspection and maintenance; built-in intelligent voltage regulator to stabilize 24V bus voltage, protect ECU, batteries and on-board electrical equipment from overvoltage damage.

Integral die-cast aluminum casing with high structural rigidity, anti-vibration and oil resistance, adapts to harsh working conditions such as road bumps, engine oil splashing and high temperature in the engine compartment.

8PK heavy-duty pulley matches engine drive belt, high friction transmission, no slipping during high-speed operation, guarantees continuous power output.
