Did you read the specs listed in the ad before you bought it? Input voltage min/max - output voltage min/max - input/output voltage differential. Did you look up the controller chip's specs? Did you look at the voltage rating on the output capacitors to give you a hint of what its maximum output voltage is? The electronics hobby or profession requires attention to detail, (and insulated screwdriver shafts.) I've been at it for 65 years. I bought what look like the same modules, and mine work fine within the input and output voltage specs, though I did add some Mix 42 ferrite on the outputs to reduce switching transients for my 28 Volt application. BTW, if you run them at 28 volts like I did you'll find that at the maximum current allowed they won't produce 250 Watts. They will only produce the power of the maximum current specified for the device times the voltage you run them at. P = I * E Good luck
This module looks like it can handle up to 50 volts, as evident by the voltage rating on the input and output capacitors, and it is using a TL494C PWM control chip to control the boost converter. I am not sure if it can output 250 watts, but it certainly seems like it can handle the power. Funny enough, AliExpress also sells a different version of this that looks about the same but claims it can output 600 watts!
Dude try teach circuit invetroring for important but small things to like and view go high
