Product Overview
  • Model Interpretation
    Compared to the "12" series, the "14" design serial number incorporates two key optimizations with tangible application benefits: first, core materials are upgraded to low-loss silicon steel sheets, which reduce hysteresis loss during operation and boost overall energy utilization; second, winding processes are refined to enhance insulation stability, making the transformer better suited for scenarios with mild load fluctuations. The suffix "NX2" likely serves dual purposes: it may correspond to a more compact structural layout (reducing installation space occupancy for narrow power distribution rooms) and tailored adaptation to specific load fluctuation scenarios (e.g., intermittent power demand in light industrial settings). "Energy Efficiency Class 2" cuts energy consumption by roughly 10%-15% compared to Class 3, which not only meets medium-level energy-saving requirements but also avoids excessive energy expenditure—ideal for users seeking cost-effective efficiency rather than top-tier 节能 performance.
