    Two serially placed led drivers?

    I am seeing a strange design and i was hoping somebody could shed some light. I have a regular driver (42W constant current, 28-56v, 0-10v dim), but upstream (feeding to the line/neutral inputs) there is another driver that appears to be only acting as a filter. I wanted to understand before...

    LED drivers not giving out correct voltage

    I've just bought a bunch of led drivers (12VDC), but they're giving out between 24-32VDC. I'm assuming their faulty. However, testing my old halogen drivers (12VAC), the voltage their outputting on a dimmer (fully on) is only 7VAC. My multimeter seems fine - just getting a bit confused as...

    In a new building about 400 TCI LED drivers of type 122692 were installed. This concerns DALI drivers. The vast majority of these drivers are in a dimmable setup (DALI).

    Led Drivers

    Evening chaps, when selecting drivers do we need to allow a margin over the lamp wattage ? Say a 10 w for a 6w lamp or is a 6w OK for a 6w? Cheers

    12V LED Drivers

    I am gradually replacing filament & halogen bulbs with LED versions. Whilst some LED lamps work okay with standard 12V transformers, the transformers don't like low current devices, resulting in flickering. Since the idea is to save money and energy, I don't really want to outlay large sums of...
