12V Dimmer

A dimmer is quite unusual in a caravan or on a boat. Here we describe how you can make one. So if you would like to be able to adjust the mood when you’re entertaining friends and acquaintances, then this circuit enables you to do so. Designing a dimmer for 12 V is tricky business. The dimmers you find in your home are designed to operate from an AC voltage and use this AC voltage as a fundamental characteristic for their operation. Because we now have to start with 12 V DC, we have to generate the AC voltage ourselves.
We also have to keep in mind that we’re dealing with battery-powered equipment and have to be frugal with energy. The circuit that we finally arrived at can easily drive 6 lamps of 10 W each. Fewer are also possible, of course. In any case, the total current has to be smaller than 10 A. L1 and S1 can be adapted to suit a smaller current, if required. Note that the whole circuit will also work from 6 V.

1200 Watt AC Dimmer by Triac Q4006LT

This is Power AC Dimmer 1200 watt size. It is use a triac Q4006LT. Friends ever tour is the foreign land has and to ever reach rest a hotel. On bed head has will head bed fire decorates. It has a button opens-close and a button controls the brightness with the equipment this/these be AC Dimmer follow our circuit can fine to decorate.

The VR1 for control the light besides when friends apply TRUE work. The Q1 -Q4006LT , should hold heat sink with and should be careful specially prohibit catch one ( part ) which part in the circuit , because read will bump against the electricity can suck. I hopes this circuit , friends can induce apply be AC Dimmer with electric other appliances bump against emphasize kind coil heat equipment , be lucky please yes.

AC220V Light Dimmer 100W

This circuit has can to turn down a light bulb arrives at 100W. If Triac there is tall temperature should hold Heat Sink or let off the heat. The Diac be diode that perform be formed encourage or Trigger Diode 2 kinds are way or Bidirectional. The VR1 use for fine decorate turning down fire. Caution this circuit must is in a box closes all the time that have the electricity flows through.
