8/12/2023 0 Comments Arduino relay power strip![]() Well use the Arduino and a sensor to control when the relay. It takes a few seconds to turn on the Led Strip, but I guess that's better than burning relays. In this tutorial, well be using a 5V relay to switch the current to a power outlet on and off. I bought new power supplies that had a NTC thermistor device in series with the AC line. So you have 2 sockets- 1 normal to deliver power and another that is controlled by the Arduino with relay. ![]() Maybe with a suitable USB power pack/mobile charger type that is NOT part of the relay (as the Arduino needs constant power to work to switch on/off the relay). Conversely, if you want to stop power flowing through. Power to the Arduino should be through USB. The datasheet that I found is: ĮDIT 2: for future internet users, as described on the answers below, the issue was with the surge current. This ensures that even if your Arduino turns off for some reason, the NO contact will still stay closed. PS: By burning I mean that it just stops working.ĮDIT: The relay board is a cheap AliExpress 8-relay board. What could be causing it? How can I avoid more relays being burned? Is there a "diode" for AC that could stop it from burning? Do you see anything else besides the power supply that could be causing it? This gives you control over other circuits or devices, without the risk of damage to the arduino or dangerous situations. The Relay Controlled Power Bar is designed to allow you tosafelycontrol an outlet device that operates at 3 48VDC or 12 120VAC. ![]() And some of the loads are higher than this power supply. I'm pointing at the power supply as the the guilty one here as I have hundred other loads that didn't burn. The other relays on the board are still operational. The relays usually stop working when turning on or off the relay. Description Say goodbye to hazardous high voltage wiring and create the Internet of Things with safe, reliable power control. The current, in both cases, is below the rated 20 A of the power supply. It doesn't matter if it is a 1 m long LED strip or a 16 m long led strip. WOR was the first New York station to carry programming of the Columbia Broadcasting System, premiering on September 18, 1927. I have already 7 or 8 burned relays from different LED strips. ![]() It has 110 V AC input and is rated at 12 V DC, 20 A. This relay powers on and off an AC-DC power supply. ![]()
