DRIVE HOME AUTOMATION LIGHT LOW HYSTERESIS
SCHEMA DRIVE LIGHT:
This device serves to vary I'intensite one or more incandescent bulbs up to a load of 1000 watts maximum, by changing the amount of energy applied to the same bulb.
The arc of setting is very gradual with a particular bias circuit reduces almost to zero the unpleasant effect of hysteresis present in almost all electronic regulators of light. The device is equipped with a special filter that greatly reduced the spread RF interference

It is also recommended not to try to use this drive with neon bulbs.
It is advisable for those who use the device has the maximum power for prolonged periods, put a heat sink TRIACT1.
