  • Indicator lamp 

  • Thermoplastic casing





5-step transformer

The REU is a single-phase transformer designed to control the fan speed by altering the supply voltage in five fixed steps.
REU has two knobs for setting low and high speed. By using an external change-over contact, you can switch between the two speeds set on the knobs.

Manual adjustment

The REU is designed for simple use. The steps are adjusted manually using the control knobs on the front of the unit. 


Thermoplastic casing

The REU has a self-extinguishing thermoplastic casing for added durability and safety. 


The REU is a single-phase transformer designed to provide effective and durable fan control. The fan speed is modified by altering the supply voltage in five fixed steps. The REU has two control switches, one for low fan speeds and one for high fan speeds. Switching between the low and high settings is carried out by an external change-over contact. This could be a thermostat or a timer. 

The indicator lamp on the front shows when the transformer is in operation. The fuse can be reset from the outside. For added durability and safety the REU has a self-extinguishing thermoplastic casing. The supply voltage for the unit is 230V 40/60Hz. Fans with external thermal contact must always be connected to a motor protection device.
