![]() It takes a few seconds to turn on the Led Strip, but I guess that's better than burning relays. Relays are used where it is necessary to control a circuit by an independent low-power signal, or where several circuits must be controlled by one signal. ![]() I bought new power supplies that had a NTC thermistor device in series with the AC line. Surely the most straightforward way of creating a smart power strip would be to take an existing model and hack in some relays that you could fire with a. 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. 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? 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. A relay is a programmable electrical switch, which can be controlled by Arduino or any micro-controller. The other relays on the board are still operational. Allow electronics with low voltage to control high power load, example from Arduino to AC light bulb. ![]() Put simply, you can now turn on and off lamps, fans, solenoids, and other small appliances that run on up to 250VAC or DC power using any Feather board. Depending on the operating principle and structural features relays are of different types, such as: 1. The relays usually stop working when turning on or off the relay. It gives you power to control, and control over power. Step 1: Basics A Relay is a large mechanical switch, which is toggled on or off by energizing a coil. Conversely, if you want to stop power flowing through. The current, in both cases, is below the rated 20 A of the power supply. This ensures that even if your Arduino turns off for some reason, the NO contact will still stay closed. ![]() It doesn't matter if it is a 1 m long LED strip or a 16 m long led strip. With the IoT Power Relay you can easily control the power going to a device with an Arduino, Raspberry Pi or other single-board computer or microcontroller. I have already 7 or 8 burned relays from different LED strips. What kind of transistor It depends on power consumption (how many LEDs). If you need to fade led you should use transistor. It has 110 V AC input and is rated at 12 V DC, 20 A. 1 As Gerben said relays are only for on/off control. This relay powers on and off an AC-DC power supply. ![]()
