Systemair Ree 2 Speed Control

Thyristor speed controller

– REE 1 or REE 2 surface- or flush mounting

– REE 4 only surface mounting

For the manual control of speed and air flow of electrical fans, AC-induction motors of universal motor- and permanent-capacitor type. The jetproof IP 54 enclosure is achieved with the included surface mounting case. (Flush mounting without the surface mounting case, gives a splash proof IP 44 enclosure also suitable for highly demanding enviroments as bathrooms etc.) Several motors can be connected in parallel as long as the total current does not exceed current range. Starting currents must be considered when choosing speed controller type. Fans to be used with this controller require a built-in overheating protection and should be designed for thyristor speed control
