Most of the MEAN WELL constant voltage LED drivers stocked by ADM can be used in constant current mode. EXCEPTIONS The exceptions are the PWM, IDLV and APV series LED drivers. HOW DOES IT WORK? The actual current that will be delivered by the LED driver is shown in the product data sheet as the “Rated Current”. You simply run the driver at the maximum current output. The MEAN WELL LED driver will then ‘clamp’ this current and continue to operate as a constant current LED driver. WHAT IF I CAN’T FIND A MEAN WELL LED DRIVER WITH REQUIRED OUTPUT? If you cannot find a MEAN WELL LED driver with

ADM stocks the MEAN WELL range of Ultra Slim DALI Bus Power Supplies. There are two different types available: MEAN WELL DLP-04R MEAN WELL DLP-04L Any product that can decipher the DALI protocol needs to be able to transmit a DALI signal down a DALI Bus. Any device such as a light fitting, light panel, wall controller, etc. that doesn’t have its own means to produce the DC voltage Bus line will require one of the above power supplies to create one. That device will then transmit the DALI signal down that line. These two DALI Bus power supplies are low-cost and compact, so they take up minimal

We often receive calls from customers who have installed a new LED driver to power a LED downlight, only to discover that they have problems.The LED downlights may flicker, flash, be too bright or too dull. A common cause is often a mismatch between the LED driver purchased and the type of LED driver the light fitting needs. Many LED downlights have integrated electronics to regulate the current being supplied to the LEDs of the fitting. Usually, such downlights will require a constant voltage LED driver. If the LED driver has a PWM output this can cause some incompatibility problems between

ADM stocks the MEAN WELL range of DC to DC LED DALI LED drivers. There are two different types available: Step-up DC to DC LED drivers Step-down DC to DC LED drivers You can browse the product range on this website, by clicking on the follow link: DC to DC LED Drivers Step-Up DALI DC to DC LED Drivers There are two different versions of the MEAN WELL step-up DC to DC LED Drivers available: Series Input Voltage LDH-45A 9 ~ 18VDC LDH-45B 18 ~ 32 VDC The below tables show the different current options available: Part# Output (VDC) Output (mA) LDH-45A-350WDA 12 ~ 86 350 LDH-45A-500WDA 500 LDH-45A

Not all LED drivers manufactured by MEAN WELL have Australian electrical safety approvals. This is one of the reasons why not every single model of MEAN WELL LED driver is listed on the ADM website. In Australia power supplies fall into one of two categories: Level 1 In-Scope Electrical Equipment Level 3 In-Scope Electrical Equipment (most MEAN WELL LED drivers) Before a Level 3 power supply, such as a LED driver can be imported into Australia, it must first of all have been submitted to an authorised test laboratory to ensure it complies with Australia’s electrical safety regulations. If it

We are often contacted by electricians, who are trying to repair a high bay LED light that has failed.Typically, the high bay light in question is one that has been imported and was cheap to buy. The first assumption that is usually made is that the LED driver has failed. ADM recommends testing the output from the LED driver before going any further, as we have now come across several cases where it is the LEDs themselves that have failed. LED Failure The LEDs usually fail, because they have been connected to a constant LED driver in parallel. If you would like to know why this causes the LEDs

Are you finding yourself constantly being called out to LED streetlamps that have failed? You may have tried replacing both the LED luminaire and its power source, only for the streetlamp to fail again? In this article, we explore common issues with failing LED streetlights with a handful of possible solutions to help guide you. Issue One: LED luminaires powered by a Constant Current LED Driver have their leds connected in parallel. Constant current LED Drivers are used to power LEDs that have no internal current regulation. When you connect multiple LEDs to a constant current LED Driver in

By its own definition constant voltage LED lighting requires a specific supply voltage that remains constant. Typically constant voltage LED light fittings require either a 12VDC, or 24VDC power supply. Constant voltage LED drivers ensure that the supply voltage remains constant, despite any fluctuations in mains supply voltage. However, installers of LED lighting need to be aware that running long lengths of DC cable from a LED driver to a LED light fitting can result in voltage drop, so that by the time the voltage reaches the LED light fitting it is lower than what is required for the LED

One of the biggest challenges with installing outdoor lighting is access to power.Running a 240VAC power supply to various locations can be expensive and not always practical, especially if the project is an upgrade of an existing outdoor space. The obvious and best solution is to use solar powered lights. A solar panel is used to charge a battery during the day. In the evening the battery supplies powers to the LED lights inside the bollard. Of course a LED driver is still required to take the DC power from the battery and to convert it the required constant current output that is required by

ADM stocks a nice simple solution from MEAN WELL to power up and and dim LED lights. This is ideal for both securtity and energy savings applications. Leaving lights on permanently to light up areas such as dark alley ways, concealed doorways, loading docks, warehouses etc. can use quite a bit of power and leave you with a significant power bill. This cost can be reduced by both using LED lighting to save energy and having it only come on, when someone is approaching the area in question. The simple solution is to use the MEAN WELL PIR-045 motion sensor, in conjunction with a MEAN WELL LCM
