Gavita EFM1 AC Fan Controller

Product detailed description

Not everyone can afford expensive EC motors or just don't want to throw away good old functional ventilation motors, even though they can only be controlled by triac controllers.
Even in this case, you can take full advantage of the new generation of Gavita Master Controllers EL1 / 2 F GEN 2.
All this is possible today thanks to this device. You can easily connect the EFM1 AC Fan Controller to the controller with a data cable and connect the socket to the supply and the required motor.
This way, you can easily incorporate your good old engine into the adaptation of your growing room to modern technologies, without the need to redesign existing ventilation and invest in new EC engines.

On low speed we use burst modulated AC control to reduce losses and reduce hum in the fan motor, on higher speed settings the controller switches to phase cut control, which is more efficient in those stages. The EFM1 can be plugged in between your power outlet and fan, and a simple signal wire is all that is needed to control it from the ELF.
