npn How to avoid Relay buzzing noise? (LDR dependent ... Most of the buzzing will be solved by adding a capacitor to the power supply. Rule of thumb is 2200µF A drawn by the load, so order magnitude 470µF should be sufficient, 4700µF is somewhat overdone (but not necessarily bad). Why is my low voltage relay buzzing? What should I do? To fix the issue, swap out a working switch connected to a different relay and wire it to the buzzing relay. If the buzzing sound stops, then replace the defective switch. If the relay continues to buzz, then it is time to replace your relay. Relay Buzzing the12volt Relay Buzzing I have a 03 Saturn ION with an overhead installed on the roof. However, the overhead did not support negative trigger for the dome light. I used a relay to switch the polarity going into the trigger. It works fine now, but now the relay buzzes every time the dome light turns off. Ho Buzzing of relays | Electronics Forum (Circuits, Projects ... Dear friends i have bought a 12VDC relay for project work.The line voltage is 220VAC so i bought a 12VDC transformer to convert the 22ov into 12VDC for smooth operation of the relay but i keep hearing this BUZZING sound anytime the relay is working. Relay Makes Odd Buzzing Noise the12volt Relay is making a Buzzing noise anytime the coil actives or deactivates. 86 is to a dimming dome light wire it dims up then dims down on shut off... DPDT Relay switch question | All About Circuits I used a 5amp 28VDC socket style relay I had laying around just to see if everything would work properly. Then I bought a 30amp 28VDC. Funny thing is, the 5amp worked way better than the 30amp. The 30amp relay got extremely hot and started buzzing in a matter of minutes. Relay Harness buzzing!? HiDplanet : The Official ... You don't need such big capacitor (4700uF) like the the guy used in the other thread, as you are only need enough power to smooth the PWM for triggering the relay. My experience a 220uF 50V capacitor is enough, and probably even smaller will work but I didn't tried myself. Relay Buzzing | Electronics Forums The components probably have identifying markings on them. You sound like you might know how to solder. If you (WITH THE POWER OFF DISCONNECTED, OF COURSE), un solder one leg of each diode, you should be Buzzing RELAY. Please help! | DSMtuners My point is that in my buzzing relay case the relay was fine, the component that it was associated with was fine (the starter and solenoid tested fine), but there was a problem in not being able to deliver power to the starter. Maybe this experience will be helpful and give you some further ideas as far as places to look. What would cause the relay to buzz? | Yahoo Answers I have a 24 ft. Chevy T6500 which has a relay stars running real hot when the headlights have been on for a while. The dash lights go out and the tail lights go out after a few minutes immediately when the relay starts buzzing.
