The EC 12038 pairs a brushless DC motor with a wide 100–277 V AC input, delivering DC efficiency on AC power. In its 120 × 120 × 38 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 12038 provides a 120 × 120 × 38 mm EC platform with wide-range mains input and stepless speed control.
Each EC 12038 is bench-tested after a complete aging cycle at our Shenzhen facility, and test records are retained by serial batch. Tell us your voltage, duty point and environment and the confirmed curve for your order will match the sample you approved.

The EC version of EC 12038 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 12038 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 12038; specify the signals you need when requesting a quotation.
