REB-2,5N thyristor regulator, surface mounted for 1-phase fans (230V) with power above 20W and below 230W, dimensions 80x80x68 40025030

Thyristor regulators - regulate the rotational speed through stepless voltage changes. The voltage is regulated by a thyristor.

Application:
Accessories that allow you to change the fan efficiency by reducing the supply voltage.

REB 1, REB 2,5 - single-phase (230V, 50Hz) stepless thyristor regulator, available in surface-mounted (N) and flush-mounted (NE) versions. The device has the ability to adjust the lower range of the setting, it is equipped with a switch integrated with the adjuster.
Attention:
Speed regulators can only work with fans adapted to speed control in one of the above-mentioned ways.

All thyristor regulators can cause engine noise at low speed - It is not recommended to lower the speed below 50% of the nominal value.
