Speed controller
Single-phase, continuously variable thiristor speed governor in surface mounted version. Controller designed for cooperation with electric engines supplied by single phase (230 / 50Hz) current, adapted for voltage speed control.
Application
TLR 15 DS, TLR 25 DS - single-phase (230 V / 50 Hz) stepless thyristor regulator, available in surface-mounted version.
The device has the ability to adjust the lower setting range, it is equipped with a switch integrated with the adjuster.
Caution
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 reduced speed. Due to the deterioration of engine cooling at reduced revs - it is not recommended to lower the engine speed below 50% of the nominal value or, if possible, to use external cooling.
