Hy to all,
I want to design a dimming circuit for a 300W Halogen lamp that is controled by a PWM signal from a microcontroler (jn5148).
I use a simple circuit using a triac BTA16 and a optocoupler.
The PWm signal enters the optocoupler and commands the BTA 16.
In this configuration I succeded in making dimming but thete is a problem.
After a regular period of time the lamp goes full power (100%) and then dimms to 50% and the cycle repeats again.
I am running out of options.
Waiting for a replay.
Best regards.
Alex
