EC Fan What is EC technology?
EC stands for Electronically Commutated, and it combines AC and DC voltages bringing the best of both worlds; the motor runs on a DC voltage, but with a normal AC supply.
EC motors have several benefits. Because EC motors have no brushes, they do not spark or have a short life due to brushes. Other advantages include the fact that they do not waste power because the electronics control the stator; they provide better performance and controllability, and they run cooler than induction motors; In terms of size, small motors can achieve the same output as traditional DC or AC motors.
Power distribution is much cleaner with an EC motor. Brushless DC motors depend on a separate DC power supply. And an AC motor’s power supply usually adds extra cost and complexity. EC motors can connect directly to AC main power supply with their integrated electronics. They do not completely depend on voltage or frequency; hence, small changes in voltage do not affect motor output.

The EC fan is more windy than the AC fan, more energy efficient, and can work in the 70V – 270V voltage range, such as work under on 110V, 120V, 220V, 240V ,the fan speed are the same.

Overview

A quiet cooling fan system designed to be placed on top of AV components such as receivers, amplifiers, and DVRs. Maintaining an optimal temperature for components prevents overheating, ensures constant performance, and extends their lifespan. The controller on the front of the cooling system features a smart thermostat trigger and fan speed control. The steel enclosure houses three dual-ball bearing fans that pulls heat out of the component and exhausts upwards. Its low-profile design enables the unit to fit in tight spaces. Includes corded power adapter to plug the fan system through an outlet.

Intelligent Programming

There are three programming settings available which includes two temperature trigger modes. The fans can also be set to run continuously or be turned off. Four fan speeds are available for each active mode and will determine the speed at which the fans run when they are triggered. This ensures optimal airflow and noise levels for your application.

Design and Construction

Each system features dual-ball bearing fans rated at 67,000 hours and are certified by CE and RoHS. Fans contain a PWM-controlled motor used to minimize noise during speed variations and are suspended in mid-air with silicone mounts to absorb vibrations. A low-profile design allows the unit to fit in applications with a limited height clearance. Aluminum and steel construction enables additional components up to 30 pounds to be stacked on top.
