    Quite a good power supply. I am a professional electronics technician and I was impressed by the fact that there are no RF indicators present.

    I won't go into whether it is stable (noise, fluctuation, etc.), because remember that it is Linear and not SMPS.

    The only negative aspect (for me) is the fact that the fan runs continuously as soon as it is turned on. This means that if you have it on for several hours and there is silence where you are... it can be a bit annoying (constant fan noise).

    Of course, this can be fixed (I have already done it) by placing a Normally Open thermal switch (e.g. 45 °C) on the heatsink internally, which monitors the temperature and controls the fan. So, the fan will only start when there is a load and the temperature on the heatsink increases slightly. With this intervention, the fan only spins when necessary.

    In its very positive aspects, I struggled a lot to measure its noise and ripple and found it to be in accordance with its specifications for various loads. It is an unexpectedly good linear power supply.
    It is a bit noisy and very difficult to set the desired voltage and current limits (I can't understand why manufacturers insist on fine+course when they can't make it work), resulting in the inability to adjust it for a current limit of 0-20mA but only for higher values.
    However, for its price, it is excellent.

    For amateur use, testing motors, powering components, etc., it suited me just fine. It is quite sturdy as a construction. It makes minimal tolerable noise.

    On the positive side, it has a rear fan and does not overheat.
    On the negative side, the fan makes a lot of noise...

    Other than that, it seems fine. The potentiometers are a bit more sensitive to changes than I would like, especially in fine tuning.

    Very good, perfect, only it doesn't have sound when there is a short circuit
