It’s all over the news today. There is talk of the obligatory decision of Naples to sell their key player, Higuain, to the Juventus Club.
Without delving into this sector, also the purchase of your Regulator is an obligatory choice compared to the Fan you are using, if you have an AC Fan, EC Regulator and vice versa.
Despite this, we frequently receive requests for assistance from operators who do not know the differences and benefits of the various solutions.
This is why I have prepared a mini guide that shows the difference between AC and EC Fans.
In the field of AC Fan regulation, you can use different types of regulations, and all these devices entail an adjustment of the electric output furnished to Fans. Generally, Cut-off, Voltage Scaling and Inverter devices are used. In the case of EC Fans it would suffice to furnish a signal control since the extension of the electric output is already directly applied on the Fans. The Control Signal may be 0-10V or RS485 MODBUS
