The EC 12025 pairs a brushless DC motor with a wide 100–277 V AC input, delivering DC efficiency on AC power. In its 120 × 120 × 25 mm frame it offers stepless speed control and substantially lower energy use than an equivalent AC fan.
For projects balancing energy budgets against cooling demand, the EC 12025 provides a 120 × 120 × 25 mm EC platform with wide-range mains input and stepless speed control.
EC 12025 units are produced on our own winding and impeller-balancing lines in Shenzhen, then 100 % aging-tested before packing. Performance figures in the table reflect typical delivered values; we confirm exact curves against your enclosure resistance during sampling, and speed, voltage window or connector can be tuned at no tooling cost for standard frames.

The EC version of EC 12025 uses a brushless DC motor with integrated electronics: higher efficiency, lower power draw at the same airflow, wide voltage input and controllable speed — ideal for equipment that runs long hours.
EC 12025 supports PWM (1–10 kHz), 0–10 V analog and NTC temperature-controlled modes. Speed curves can be programmed at our factory to match your thermal profile.
Standard EC input is 100–240 V AC or 12–60 V DC depending on the variant. Wide-input versions tolerate unstable grids and generator supplies — confirm the range with us before ordering.
Yes. Tach (FG), locked-rotor alarm (RD) and soft-start options are available on EC 12025; specify the signals you need when requesting a quotation.
