Features & Specifications

This kit is especially designed to control the speed of drills or any other AC-motors with carbon brushes. Contrary to the usual
dimmers, there isn't a phase cut every 1/2 period but only once per period. The moment of cutting determines the speed which can
be adjusted from 5 to about 95 %. Owing to this kind of controling, we keep a higher torque at low speed.This does not mean on
the other hand, that this circuit cannot be used for a resistive load (e.g. lamps, heating devices.).

A few advantages are :

The control range is from 5 % to 95 %.

There is an anti-RF interference circuit included.

The triac is protected against inductive voltage peaks from the motor.

The control circuit is powered by the mains, but the load supply may be derived from a different AC source. Both
voltages should have the same frequence though, and they should have completely the same phase or the opposite
phase (derived from one and the same phase out of the 3-Phase power source).

By keeping the MAINS- and LOAD SUPPLY separated this circuit is extremely appropriate for the use in low voltage
applications: e.g. in swimming pools, outdoors ...
