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.).
Assembly hints 1. Assembly (Skipping this can lead to troubles ! ) Ok, so we have your attention. These hints will help you to make this project successful. Read them carefully. 1.1 Make sure you have the right tools: • A good quality soldering iron (25-40W) with a small tip. • Wipe it often on a wet sponge or cloth, to keep it clean; then apply solder to the tip, to give it a wet look. This is called ‘thinning’ and will protect the tip, and enables you to make good connections.
Assembly hints 1.3 Soldering Hints : 1- Mount the component against the PCB surface and carefully solder the leads 2- Make sure the solder joints are cone-shaped and shiny 3- Trim excess leads as close as possible to the solder joint REMOVE THEM FROM THE TAPE ONE AT A TIME ! AXIAL COMPONENTS ARE TAPED IN THE CORRECT MOUNTING SEQUENCE ! You will find the colour code for the resistances and the LEDs on our website: http://www.velleman.be/common/service.aspx 4 Assembly hints 1.

Test & connection 17. Test & connection 110 - 240VAC LL N L M L N ATTENTION: A PART OF THE CIRCUIT IS ALWAYS UNDER MAIN VOLTAGE. TAKE ALL POSSIBLE PRECAUTIONS, SO THAT NO-ONE CAN TOUCH ANY PART. FOR YOUR OWN SECURITY AS FOR THE USERS' SECURITY. MOUNT THIS KIT PREFERABLY IN AN ISOLATING HOUSING. THE FUSE WILL MELT IN CASE OF AN OVERLOAD, REPLACE IT BY EXACTLY THE SAME TYPE. MAINS L N LOAD N N L VAC N Fig 1.0 Connect the load to the screw connector marked by "LOAD" see fig. 1. Consider the max.
Test & connection Turn RV1 completely to the left (minimal position) and RV2 completely to the right. Switch the power on. BE CAREFUL: a large part of the circuit is under mains power, do not touch it! Adjust RV2 so that the motor will have the lowest speed. It is important for the motor to start at any time, even where RV1 is put in its minimal position, otherwise there might be large currents causing sparks that burn the carbon brushes.
