Keystone Tech Class P UL LED Drivers, Case Sizes, mA
Sourcing LED drivers continues to be a ache level within the trade, as we regularly see that be the primary failure level in Gen1/Gen2 LED fixtures. A mad chase then begins for a alternative LED driver choice! Good luck discovering that very same particular driver from 4-5 years (or longer) in the past. Which is why too usually these fixtures are tossed away.
Effectively Keystone Applied sciences has been a pacesetter in ballast know-how for many years and the fashionable ballast is the LED driver. So it’s no shock that they’ve mastered the LED driver as properly! You’ll usually see Keystone LED drivers utilized in numerous different non-Keystone fixtures because of this. This contains their Class P LED Drivers which might be UL pleasant. Likelihood is, if you will get a driver half #, Keystone can cross it.
After all, with a myriad of driver decisions it might get difficult. Keystone thus created the SmartCurrent Programmable LED driver line to have the ability to substitute hundreds of drivers with just a few SKU’s. The hot button is determining the milliamp (mA) stage of the motive force you might be changing, after which Keystone can both pre-program their alternative LED driver to that stage or you may make the most of the USB know-how on the motive force and tune it your self. Be conscious of whether or not your driver is fixed voltage vs. fixed present in addition to dimming (0-10V dimmable or 120V part dimming) to make sure this performance matches up as properly.
LED Driver case measurement is one other difficult half, as a result of there’s a lack of standardization on sizing with these. Typically the scale of the case might be depending on the wattage vary, as the larger instances can deal with 100-200W max whereas the smaller drivers might be within the 10W-20W max vary. However the driver sizes run the gamut. See the motive force to get some concepts of case sizes together with AF4, AQ7, W1, U7 and U4 case sizes.
As at all times you may take a look at our LED driver catalog online and please attain out with any questions in the event you want a special match. It’s also possible to fill out our LED alternative driver questionnaire with all of the pertinent information so {that a} alternative will be sourced.
