Transformer REU, Systemair

Single-phase fan variator, where the fan speed is controlled by the supply voltage and can be varied in five fixed stages, which are controlled manually with the aid of the switch at the front. The higher speed is set using one of the knobs and the lower speed using the other. Switching is carried out by an external alternating contact, e.g. a thermostat, time switch or timer. A signal lamp at the front for operation indication. REU has a cover of self-extinguishing thermoplastic. Supply voltage: 230V 50/60Hz. Please note! For fans with extended thermal contact, separate motor protection must be used.
