Three-phase exhaust fan power-saving automatic control circuit
Source: InternetPublisher:aerobotics Updated: 2014/10/03
In some places with poor ventilation conditions, the installed exhaust fans run for a long time, which consumes electricity and is easy to burn out. The circuit as shown in the figure can make the exhaust fan M automatically stop after running for a period of time, and then run automatically after stopping for a period of time. The interval time is set by potentiometers RP1 and RP2. Latest Control Circuits Circuits
