hi, j have a 220v motor driver and i think it is a dimmer from its bt138 triac (it goes to a 220-24 trans and then to the motor) and its ic surface is erased and expunged and i don't know its number, does anyone know what this could be?WhatsApp Image 2021-08-10 at 20.20.02.jpegWhatsApp Image 2021-08-10 at 20.18.50.jpeg
