Dear friends
i have bought a 12VDC relay for project work.The line voltage is 220VAC so i bought a 12V transformer to convert the 22ov into 12V for smooth operation of the relay but i keep hearing this BUZZING sound anytime the relay is working.
Folks i am a bit confused.
I suspect that the transformer is supplying 12 VAC to the relay instead of 12VDC.I want to convert 12vac into 12VDC and need some assistance to be able to achieve this.
