Answer 4: Normally 20 days after receiving deposit, detailed product period depends on the order.
Question 5: How can I get the quotation?
Answer 5: Feel free to contact us by TradeMessenger or Email. You will get reply within 24 hours.
Question 6: What is EC Fan?
Answer 6: EC fan is a new variety in the fan industry, which is different from other DC fans. It can not only use DC voltage for power supply, but also AC voltage for power supply. The voltage can be universal from DC 12V, 24V, 48V, to AC 110V, 380V, without the need for any inverter conversion. All internal components of the motor are powered by a DC power supply,
built-in DC to AC converter, rotor position feedback, three-phase AC, permanent magnet, and synchronous motor.
Question 7: Advantages of EC fans?
Answer 7: 1. Capable of achieving control modes such as constant voltage, constant current, and constant power, resulting
in low mechanical load and high work efficiency.
2. Able to adjust the power output voltage in real-time according to load changes, and automatically adjust the fan speed to maintain stable operation when the power voltage fluctuates.
3. Low starting torque, short starting time, fast transient response, and the ability to quickly change air volume response.
4. In long-term operation, EC fans have lower energy consumption and lower maintenance costs compared to AC fans.
5. The EC fan does not require the use of additional electrical components such as frequency converters and capacitors,
making the system simpler, more reliable, less noisy, and has a longer lifespan.
Question 8:The difference between EC fan and AC fan?
Answer 8:Their driving methods are different. EC fan is a variable frequency fan based on electronic control technology, which
is driven by a DC power supply fed to the EC motor. The controller accurately adjusts the current and speed of the motor to achieve precise control of air volume, static pressure, and efficiency. The AC fan, on the other hand, is a traditional AC driven
fan that operates at a fixed frequency and voltage. The control method is relatively simple, and the air volume and static pressure can only be adjusted by adjusting the blade angle or the gearbox.
