Newbie level 6
I came acros this circuit, but I am unable to identify its use. It was sent to me by a client for designing its layout, now they want me to electrically test it. But I was not provided any detail as to what it does, please help.
- It is has 3 pins with a heat sink attached.
- It looks like a lamp dimmer circuit, but is missing a pot and has an extra resistor connected to the Gate of TRIAC.
- All resistors are 1/4 Watt rated.
