Our LED Drivers come with built-in short-circuit protection, which is activated under certain conditions; because the PSU switches itself off to prevent damage, customers can sometimes panic and claim the Driver to be faulty, which upon being returned for testing, we often find no damage whatsoever.
So, the way to understand if the Driver is damaged or not, is to remove the load (LED Strip) and completely disconnect it from its mains power input source (240V) for 5 minutes. During this period the capacitors will have time to fully discharge, which will reset the short-circuit protection function. Then, switch back on and you can test the output, either with a Multimeter or a short length of strip (avoid using the normal LED strip load, as if that is short-circuited the protection will be activated). If it still refuses to power back on, then we can look at the next step of returning.
Another reason for activating the LED driver protection circuitry could be that the Driver's over-current protection has tripped, preventing the power supply from exceeding the recommended wattage. High Temperatures, caused by lack of appropriate ventilation, can also be a contributing factor.
Before returning your Driver to us, please ensure that you properly follow the above advice, to save on the potential hassle of returning and waiting for a solution, which may take several days to resolve.
