on contacting the holder company ideal they said since we are running such low current the voltage rating can be exceeded without issue. just FYI-- not suggesting people do it, although im over by 56v.--- email quote " Since you are running at a lower current there should not be a problem with burning anything up. However, we have not tested the holders for your application and so cannot guarantee what would happen if a holder or COB fails. Since you are above our rated voltage warranty would not apply as well."

@Led gardener only thing I noticed connecting a led with a lower voltage than the CC PSU rated voltage range is that 0-10V dimming is not working as expected. In my example dim till 50% is possible, but almost not noticeable in lumens. Dim lower than 50% results in a flickering led, and below 20% the led is off... Did you notice the same on multiple other CC PSU's? Thanks.

I have a 240w 48a driver im using for a 120w light so i have some overhead on there, but id like to have another light running temporarily on a different schedule, what im thinking is I just cut off the power to the second light after the 12 hours so the original light just runs until it switches off as normal, does this make sense to do or would i be better off getting another driver? I was kind of hoping i could wire in a wifi switch for simplicity, or a plug type timer, but idk how they will act running with a DC throughput, and everything im seeing for DC timer switches on say Amazon like to go up to 36v..

DNT94channel in a way, yes - it runs as a C.V. driver up until the lights pull all the current from it, then it turns into a C.C. driver. You can use the Io adjust pot to change the point at which this occurs by lowering or raising the available current.

so i have this cheap 300mA CC driver (22-38V). when i measured it's voltage with no load attached, it has 45V (why?). anyway, i hooked it up to a salvaged TV-backlight-strip and also to an "100W" aliexpress COB (rated 30-36V). when i measured the voltage, the COB was at only 28.5V and the strip was at 37V (it was originally supplied 24V by the TV). does that mean the cob was rated wrong and the TV wasn't powering the strip with the LED's "native" voltage? great videos btw. they are invaluable
@LEDGardener
6 жыл бұрын
Thanks tazz. Constant current drivers tend to have a higher voltage than the upper limit of their constant current region when the circuit is open. Same goes for the HLGs. Your COB and strip will react differently to various levels of current. The reason your COB voltage is low is probably because 300mA is far less current than the COB is rated for. Increasing the current will raise the voltage. In the case of the TV strip on 300mA vs. whatever the TV was giving it, that's a major difference in voltage.

I’m having some trouble with single QB648 and XLG-150-H AB (27-56v CC)that was recommended. I’m new at this but my theory is that it’s running very very hot because the voltage isn’t enough on the driver because the QB648 is actually more than 56v. And because it’s an XLG constant power driver, maybe it’s dropping the voltage even further ? But somehow maintaining the same current. I have No complete understanding tbh. But I have just tried it with XBG-240-H-AB 30-60V CC( runs cool as a cucumber 101F at 170watts(. Another driver I just tried was XLG-240-H-AB ( also 27-56V CC mode) and this runs just as hot as the XLG150-H. 165f even at just 100watts.

What happens when your constant current driver exceeds the rating for the lights? Do the lights blow or do you have wiggle room? For example. I have a constant current driver rated at 2.8A and 600W but the QB288 boards are rated for 48V 0.7A-2.7A max. Can I run it at the default 2.8A and be basically 100ma over per board without worry or is that too much? And if I install a dimmer and take it down it should work fine right?
@LEDGardener
4 жыл бұрын
Plain and simple, I wouldn’t run them harder than they’re rated for. If you can get under this rating by dimming, that would work so long as they can’t get turned up to max. You’ll lose efficiency by running them this hard anyway though so it pays to ease up on them a bit.

I'm pretty sure the type you are stating as constant voltage are both constant voltage or constant current? I'm personally using an HLG-185H-54A as a Lithium battery charger and both the voltage and current are adjustable. Yes the voltage is only adjustable within the range given in the data sheet (so for the 54 model it is around 50-60v). But when you are running below your adjusted voltage it will run in constant current mode. I've verified this as the charger cannot possible get the battery up to its full voltage rating (takes a few hours) and at that point it is outputting its maximum 185 watts until it reaches the set voltage.

@@LEDGardener I did see that video, however you still evaluate the product in constant voltage mode. Then later compare the constant voltage only supply to the model that can operate in both constant voltage or constant current mode. And lastly you say again that operating in constant voltage mode can have thermal run-away condition but don't follow up with how you can set the constant current to avoid that thermal run-away. Some of what you say is accurate but there are a number of technical inaccuracies and missing information. I think the only advantage I saw to the constant current only supply you evaluated is the very high operating voltage to overcome the resistance of very long series strings. I say this with respect, I realize making a video that is accessible is very tough. I would probably got stuck in the weeds using Ohms law to calculate the voltage rather than the LED data sheets, etc. The video is very accessible.

Thanks for your feedback but I would contend you are incorrect. Thermal runaway can still be an issue if the power of the driver cannot be handled by a single light in the parallel chain. Let’s say you have 6 amps of power that’s being split between 3 lamps in parallel that can each handle 3 amps max. They’d be getting 2 amps each in this configuration, which is fine. Now let’s say 1 of the lamps goes thermal and hogs 5 amps to itself. That’s a problem, isn’t it? You would have to set the current pot to limit the driver to only 3 amps to prevent this, but in doing so, you would now only be dividing 3 amps between the 3 lamps, so they’d each get about 1 amp each under normal conditions, which may not produce the light that you need. The problem becomes more obvious with more lamps as well. What if you have 10 strips that can only take 1A max each? Are you going to limit your driver current to only 1 Amp to guard against runaway and make them all split that so they only get 100 milliamps each?

Guys, watch out when using the external "B" dim wires! this is not intended to fully dim LED lights from 0 to 100%. The external dim wiring of the "B" model just adjusts the output voltage from almost 0 to 12V, but LED lights need to be dimmed using PWM (pulse width modulation), not by voltage. It's rather intended to slightly reduce the maximum output.. let's say 12V to 11V to increase the life span of your LEDs. But not to dim your LEDs from 0 to 100 using a potentiometer.
