A failure of this nature is not covered by the warranty. This would cause the temperatures inside the LED driver to soar above their maximum operating temperature range and will cause a failure. althought these dimmable LED drivers are weatherproof, they should not be mounted in direct sunlight. Some of these also have a rugged aluminium enclosure, which makes them very resistant to knocks and bumps.Īs previously mentioned. You can browse our range of weatherproof LED drivers on this website. Can I use a LED driver outdoors?Ī number of the dimmable LED drivers ADM stocks are weatherproof. This eliminates the need for the DALI to PWM converter. More recently MEAN WELL has released versions of its ELG series and PWM series LED drivers, which have a built in DALI interface. The lowest light level you will be able to dim to is 10%, even with the LCM and PWM models, but it is a simple, low cost LED dimming solution. This can be connected to the dimming terminals on a MEAN WELL dimmable LED driver with 3-in-1 dimming. However, the newer models such as the LCM series and PWM series accept a 0-10V, PWM signal, or resistance type input and can be dimmed down to zero.ĪDM stocks a low cost 1-10V dimming pot, the D1-10 that fits into most wall plates in place of the standard TRIAC dimmer. These dimmable LED drivers can be dimmed down to 10% of their rated output. The LED driver recognises which one is being used and dims the light according to the adjustment made on the controller. The LED driver will accept either a 1-10V, PWM signal, or resistance type input. With the range of MEAN WELL LED drivers there are basically two different types of dimmable LED driver: A separate on/off switch is usually required on the AC input. There is either a dedicated set of terminals or wires on the dimmable LED driver, which the dimming controller should be connected to. With most LED drivers, a TRIAC dimmer will cause such problems as flickering.ĭimmable LED drivers usually have a dedicated dimming circuit built into them. TRIAC dimmers work by chopping the AC going into the LED driver. Many dimmable LED drivers are not compatible with TRIAC dimmers. LED drivers should never be submersed in water. This has the potential to cause a failure that would not be covered by the warranty. This can cause the tempersture inside the LED driver to exceed its maximum working temperature. Please note that LED drivers should not be mounted in direct sunlight. The 30W and 75W models are IP20 rated for indoor use, whereas the others are all IP66 rated, so can be used outdoors. We carry a 12V and 24V version of each of them. These AC dimmable LED drivers are available in 30W, 75W, 100W, 150W, 200W, 300W and 360W models. The first is the Power Source PDV series LED drivers. A chart is printed on the front of the LED driver, which shows which position the switches need to be set to in order to select the required current output. These have a set of DIP switches, which you use to set the required current. We will gladly try and help you find a suitable dimable LED driver.ĪDM stocks a range of constant current LED drivers with a user selectable output. If you do find you are having difficulty, call us on 1300 236 467. In fact ADM even has a dimmable LED driver with a 40A output! It is often more difficult to match a constant current LED driver to a LED light fitting than a constant voltage type. They can range from anything as low as 250mA right up to 2.4A and higher. There is no standard outputs when it comes to constant current dimmable LED drivers. Though there are other light fittings that call for other voltages to be used. Typically LED downlights require a constant voltage type dimmable LED driver, but this is not always the case.Ĭonstant voltage LED light fittings will most commonly need a 12V dimmable LED driver, or 24V dimmable LED driver. Constant Voltage or Constant Current LED Driver?
