How to Choose AC, DC and EC Cooling Fans

Selection Details

AC Axial Fans AC axial fans are suitable for industrial equipment powered directly from an AC supply. Common supply voltages include AC 220 V / 230 V, while other voltage options may be available depending on the model and project requirements. AC fans are widely used for continuous ventilation and cooling in control cabinets, machinery and electrical equipment. DC Axial Fans DC axial fans are mainly used in equipment with a DC power supply. Common voltages include DC 12 V, DC 24 V and DC 48 V. Depending on the model, functions such as PWM speed control, FG speed feedback and RD alarm/rotation-detection signals can be provided. DC fans are well suited to automation equipment, power electronics, communication equipment, energy storage systems and applications requiring speed control or fan-status monitoring. EC Axial Fans EC fans use electronically commutated motor technology. In suitable industrial applications, they can combine convenient mains-powered operation with electronic control. EC fans can be considered where energy efficiency, speed control or intelligent control is required.
