Characteristics of SanAce DC Fans AC, DC, EC Fans
SanAce DC fan
DC fans and EC fans are both DC cooling fans, but there are some differences between them.
Simple summary: DC input is DC, which can input AC power and convert it into DC power.
Characteristics of DC fans: DC fans are a new type of fan industry. It is different from other DC cooling fans.
It can be powered not only by DC voltage, but also by AC voltage.
The voltage range from DC 12V, 24V, 48V to AC 110V, 220V, 380V can be widely used without the need for any inverter conversion.
All internal components of the motor are DC power supply, built-in DC to AC, rotor position feedback, three-phase AC, permanent magnet, synchronous motor.
EC fan
EC motor is a DC brushless maintenance free motor with built-in intelligent control module. It has RS485 output interface, 0-10V sensor output interface, 4-20mA speed control switch output interface, alarm device output interface, and master-slave signal output interface.
This product has the characteristics of high intelligence, high energy saving, high efficiency, long lifespan, low vibration, low noise, and continuous operation.
Applicable scenarios: Commonly used in building ventilation, HVAC systems, data centers, clean rooms, and other applications that require intelligence, efficiency, and low energy consumption, especially suitable for situations with high requirements for wind speed regulation and energy optimization.
AC fan
Drive and principle: Powered by AC power, usually directly connected to the mains or generator system. The motor consists of a stator and a rotor. The stator generates a periodically changing magnetic field at different poles through alternating current, which drives the rotor to rotate.
advantage
Low cost: simple design, easy to manufacture, and high cost-effectiveness in most common applications.
Easy to maintain: simple structure, low maintenance requirements, suitable for scenarios that do not require precise control.
Stable output: High output power and mechanical efficiency, stable speed, good torque stability when load changes, and high reliability.
Applicable scenarios: Widely used in low-cost ventilation equipment, such as household fans, industrial ventilation equipment, cooling cabinets, and other places with low energy efficiency requirements.
DC fan
Drive and principle: Using DC power supply, usually powered by batteries, adapters, or power modules. The motor consists of a permanent magnet rotor and a stationary winding. The direction of current is controlled by an electronic commutator, and the driving force generated by the magnetic field drives the rotor to rotate. The speed can be adjusted using PWM signals.
advantage
Efficient and energy-saving: It has high energy efficiency at the same power, suitable for battery powered equipment.
Low noise: The silent design and speed regulation function make its noise control superior to AC fans.
Precise control: Supports adjustable speed and can meet the strict temperature control requirements of applications such as electronic devices and data centers.
Good starting characteristics: It has excellent torque performance and control performance during low-speed and low load operation.
Applicable scenarios: Widely used in electronic devices, computers, servers, automotive cooling, and industrial automation equipment that require low noise and efficient heat dissipation.
