The TGNR128 is a high-efficiency alternating current (AC) generator designed for passenger cars, SUVs, and light commercial vehicles. It delivers 14V output at 130–150A, making it ideal for powering modern vehicle electrical systems, including infotainment, lighting, air conditioning, and advanced driver-assistance systems (ADAS). The generator features a dual internal cooling fan design, which enhances heat dissipation and ensures stable performance under high-load conditions, such as during prolonged highway driving or in hot climates.
With an efficiency greater than 72%, the TGNR128 minimizes energy loss and reduces fuel consumption compared to traditional alternators. This is achieved through optimized magnetic circuit design, low-resistance windings, and high-performance bearings that reduce friction losses. The compact structure weighs only 5.6kg, minimizing space requirements in tight engine compartments while maintaining robust mechanical integrity.
Engineered for extreme environments: operates reliably across a wide temperature range of -40°C to +125°C, ensuring consistent performance in Arctic winters and desert heatwaves. The IP55-rated housing provides protection against dust ingress and water spray from all directions, making it suitable for use in wet, dusty, or muddy conditions typical of urban and rural roads.
Safety is enhanced through the use of flame-retardant materials throughout the housing and internal components, meeting global safety standards. The regulator brush assembly features a maze-seal design, preventing contamination from oil, dust, and moisture, which extends service life and reduces maintenance needs. The brushes are made from high-conductivity copper alloys, ensuring reliable electrical contact even under high vibration and thermal cycling.
The generator supports single-function, multi-function, or LIN bus regulators, offering flexibility for different vehicle platforms. It can be equipped with Zener diodes, steel pulleys, or OAP/OAD belt systems, depending on OEM requirements. All units undergo rigorous testing, including thermal cycling, vibration endurance, and full-load charging tests, to ensure consistent performance under real-world conditions.
Manufactured under IATF 16949 with ISO 9001 quality compliance. Supports white-label customization with rapid NPI cycles (14 days) and regional compliance packages (EU ECE R10, China CCC, U.S. DOT).
