Advantages of the product
- High precision: The automatic voltage regulator performs fine automatic voltage adjustment via 32 loaded steps within the set range.
- Long service life: Optimized tap switch design prevents arcing during regulation, extending the automatic voltage regulator mechanical lifespan to 1 million cycles.
- Low maintenance: Fully sealed high-protection structure delivers excellent weather resistance, enabling long maintenance-free operation with a 20-year design life for the automatic voltage regulator.
- Low loss: Single-phase structure cuts iron and no-load losses effectively, keeping total loss of the automatic voltage regulator below 0.1%.
- Strong overload capability: Rated for 55°C temperature rise, the automatic voltage regulator supports 12% overload under 65°C working condition.
