    I bought a rgb led strip and I have a question: Can the power supply be connected to the power supply all the time? It's warm even when the leds are off. When I disconnect the power supply, the driver does not save the last color and hence this question so that I do not have to configure each time.

    Thanks for understanding what I think is a stupid question.

    If that's what you want, so be it. The power supply is warm because it draws electricity for its operation, even when it is not powering the receivers.

    Will it not shorten the life of the power supply and is it possible for the power supply and LEDs to be damaged?

    LEDs are not affected, but the life of the power supply may be shortened.

    And is there a possibility that such a power supply will start to smoke or explode?

    In practice, it rather stops working.

    Two more questions: Will such a power supply significantly shorten its life (e.g. to several months)? Is it possible to buy a driver that saves the settings when the power is turned off? I have a 5m SMD5050 tape

    You probably have a faulty power supply, it should not heat up in no-load condition unless it is over 100W.

    Don't scare people unnecessarily.
    A "warm" power supply, a relative term, does not mean that it is faulty.
    Lifespan shortening is fantasy.
    The life time depends on the quality of the electrolytes that the Chinese put into the power supply.

    Maybe a friend will write what power supply it is or where it was bought then it is easier to "assess" the quality.
    I have a 6m belt built in with the controller and the power supply is not "warm" and is constantly under voltage.

    Hello, I have a power supply constantly under voltage for 7 years without interruption because the tape is controlled by 12v and I don't think it draws much current in idle state, it has even survived the tape because I recently replaced it and best of all I'm not convinced about this statement but I think maybe it's have a positive effect on the service life of the transformer. I think so because the transformer Sn / nn also does not turn on under load, please tell me wise heads, I'm curious if it's true.

    Calculate using an energy meter how much you pay for this heating per month - it will make the decision easier.

    The power supply is some noname YL-1250.
    Output 12V 5A
    Thanks for the replies, but now I'm worried about the temperature during use. After about 30 minutes of work with the LEDs on, the power supply got quite hot, it even starts to burn when in contact with the hand. Is this normal too? Of course, I turned it off for fear of damaging it. In general, the power supply is light for its size and heats up mainly in one place on a small surface.

    The power supply is 60W, and how much is the tape? It's probably just as warm here.

    The tape is 5m, and the auction says that it consumes 4.8W per meter. It is a LED strip with 5050 diodes

    It has 60 volts at the input or output because the car is giving something else :?:

    Either this power supply is not 60W or the RGB ones are not 24W ;)

    The author states that the output, and I meant 60VA, not Volts.

    So is the PSU too powerful?

    The power supply is fine because it has more power than the receiver needs.

    It's weird that it heats up when it's not even half loaded.

    Could it be a poor quality power supply? Or maybe the power supply is too powerful and converts a large part of unused energy into heat, hence this temperature? What is the allowable PSU temperature? I'm wondering if I should leave it on for longer and see if at some point it won't get any hotter. Can this damage the leds?

    However, the controller can accept a maximum of 6A.

    It says 5A

    5A is the output in the power supply, while the LED driver accepts a voltage of 12v and up to 6A, so theoretically the power supply is good. Do you suggest changing the power supply?

    This radically changes the form of things V and VA

    So there's something wrong. Once a friend also bought two similar RGB sets on Alledrogo, one power supply lasted a few days, the other over a week and gave up the ghost, buying a solid power supply with a power reserve of 30% made him enjoy colorful LEDs to this day.

    A good move would be to check how much this set really consumes power because, as I wrote, it is impossible that the power supply does not give 5A or RGB consume more than declared by the seller and I would think about the latter, because probably wanting to sell the product, he underestimated the power of the lights ;)

    How can I check how much power the LEDs need? The seller wrote back to me that the power supply heats up strongly and there is no risk of overheating.

    An ammeter would be useful.

    I have a multimeter. Should I set it to scale 10 and connect it with a plus on one side of the tape and a minus to the end of the tape? Probably a stupid question, but I don't want to burn anything.

    The ammeter is connected in series, not in parallel. A colleague described the connection of a voltmeter.
    You need to disconnect one cable from the power supply, plug in the ammeter (select the appropriate pins in the meter, a separate pin is used to measure the current in the range of up to 10A)
    Do not measure from the controller to the tape because the measurement will be incorrect, the ammeter must be connected between the power supply and the RGB controller and gradually increase the light and color power.

    Can the LED power supply be connected to the power supply all the time?

    According to the description, this strip consumes 4.8W per meter, but is it when all the colors in the RGB LEDs shine at once?

    I'm afraid not, and that would explain why the Imax of the controller is 6A, i.e. ... 4.8W * 5mb = 24W * 3 RGB colors gives 72W of the entire system, let's divide it by the voltage of 12VDC and gives 6A :D

    So a 100VA power supply is needed ;)

    The actual maximum power consumption of 1 meter of tape is 14.4 W

Topic summary

The discussion revolves around the safety and implications of keeping an LED power supply connected continuously, particularly for RGB LED strips. Users express concerns about the power supply heating up even when the LEDs are off, questioning whether this could shorten the power supply's lifespan or lead to potential hazards like smoking or exploding. Responses indicate that while the LEDs themselves are not affected, the power supply may experience a reduced lifespan due to constant operation. Users also discuss the quality of the power supply, with some suggesting that a faulty or low-quality unit could overheat. The conversation includes technical details about power consumption, with calculations indicating that a 5m SMD5050 LED strip could draw significant power, necessitating a power supply with adequate capacity. Recommendations for measuring power consumption and considering a higher-rated power supply are also provided.
