Product Overview

  • Model Interpretation

    In comparison to the "12" series design serial number, the upgrades of the "14" series have clear value-oriented goals: low-loss silicon steel sheets are used for the core material, which reduces magnetic loss during operation and directly lowers daily power consumption; the optimized winding process improves insulation reliability, cutting down on downtime and maintenance costs caused by component failures. The design of the suffix "NX2" is more focused on scenario practicality—it may refer to a compact structure tailored for narrow power distribution spaces (reducing site rental or renovation costs) or a customized design for specific load fluctuation scenarios (e.g., intermittent power demand in light industrial workshops, preventing equipment damage caused by sudden load changes). "Energy Efficiency Class 2" reduces energy consumption by approximately 10%-15% compared to Class 3; this not only meets medium-level energy-saving standards but also helps users save a considerable amount of annual electricity expenses, balancing the investment in energy conservation and the resulting returns.
