Speed controller
In order to control the speed of AC motors continuously, an electronic speed controller or speed controller based on phase-angle or phase-angle control is required. A commercial dimmer (ohmic resistor) cannot be used as a speed controller. The motor will hum extremely loudly due to vibrations of the copper windings in the motor and may be irreparably damaged. Motor windings consist of wire painted for insulation, which can then wear through due to friction. A short circuit in the motor is the result.
Our speed controllers are based on the phase angle control, and have a control range of about 30 - 100% of the speed, depending on the motor type. The minimum speed can be preset by means of a small adjustment screw behind the front cover of the speed controller, to guarantee a safe engine start-up even at the minimum speed. Please note that many moptrors require a minimum speed for self-cooling, which cannot be arbitrarily reduced with a speed controller, otherwise the engine üoverheats.
We can supply you with speed controllers and speed adjusters that can control almost any motor power from 1.5 to 10A. WS 1,5 and WS 2,5 models are also suitable for flush mounting in standard flush boxes and for use with any switch system with 6 mm axis. Fast and trouble-free delivery is guaranteed.

WS1,5: Speed controller für AP and UP mounting with central control knob. Start-up on high power. | WS1,5-WS2,5: Installation in third-party switch systems with 6mm axis with accessoriesör of the system manufacturer. | WS1,5 - WS2,5: Flush-mounted version without housing, frame and rotary knob. | WS1,5-WS2,5: Suitable für any standard UP box with frame, rotary knob and cover plate. |
Common features - The minimum speed can be set in the device on a potentiometer (please note that the motor still flüß ssig anläuf). When connecting several fans to a speed controller, at least 10% reserve load must be planned.
WS1 - WS 10 - Housingäuse plastic, color light gray / white;. Suitable for surface mounting. Protection class IP54.
WS1,5 - WS 2,5 - Suitable for any switch system with 6 mm - axis with accessories of the system manufacturer.
The technical principle of phase angle control, on which speed controllers are based, can cause a sometimes disturbing humming noise in the lower speed range. In noise-sensitive areas (e.g. bedrooms), use step transformers to control fans.
