velleman K8026 3.5A Dimmer with Potentiometer
Due to its small size, this small dimmer easily replaces an existing switch, permitting you to vary the brightness of a light or group of lights. The dimmer may also be used to adjust the speed of a motor, vacuum cleaner, or any other motor with carbon brushes. A mains suppresser is provided eliminating unde-sirable RFI. It is not suitable for halogen lamps.
Specifications
- protected against induction voltage peaks
- Load: 3.5A (750W at 230V and 380W at 110V)
- suppressed according to EN55015
- PCB dimensions: 60 x 60mm / 2.4 x 2.4”
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.
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. When solder rolls off the tip, it needs cleaning.
- Thin raisin-core solder. Do not use any flux or grease.
- A diagonal cutter to trim excess wires. To avoid injury when cutting excess leads, hold the lead so they cannot fly towards the eyes.
- Needle nose pliers, for bending leads, or to hold components in place.
- Small blade and Phillips screwdrivers. A basic range is fine.
- For some projects, a basic multi-meter is required, or might be handy.
