MEAN WELL has expanded the number of output current options on the LCM series constant current LED drivers. Another useful feature of the LCM series is that they have is the ability to control up to 10 units synchronously, with one LED driver acting as a master, and the other 9 as slaves. As well as having the 5 options that are shown in the data sheet there are more than double the number of options as shown in the below tables: LCM-25 Model Output Current Options LCM-25 LCM-25DAS LCM-25KN 350mA, 450mA, 500mA, 550mA, 600mA, 700mA, 800mA, 900mA, 1050mA LCM-40 Model Output Current Options LCM

You may already be aware that ADM stocks a comprehensive range of the MEAN WELL HLG and ELG series LED drivers in our warehouses around Australia. What Does the AB Suffix on a MEAN WELL LED Driver Part Number Mean? Customers who are familiar with MEAN WELL’s HLG and ELG series LED drivers may have noticed that some models have an ‘AB’ suffix to the part number. Up until a few years ago only the following versions were available: Suffix Description No Suffix (Blank) Fixed output, IP67 'A' Suffix Output voltage and current can be trimmed via potentiometers. IP65 'B' Suffix 3-in-1 dimming 0-10V

If you are working on a lighting design or installation that involves the use of multiple constant current LED drivers, there could be a far more cost-effective method of powering the LEDs using DC to DC LED drivers. To demonstrate this, we will work on an example installation that involves 10 LED luminaires, each requiring a 350mA LED driver with a 15-28VDC forward voltage range. The immediate solution that may come to mind is to use 10 constant current LED drivers to take the incoming 240VAC power and supply the DC power at the correct current. Instead, it would be cheaper to buy one

ADM has had many customers asking if we can supply a dimmable LED driver that would work well with the latest push button dimming switches. The Power Source PDV phase cut dimmable LED drivers should work well with most push button dimmers. To be sure of this we carried out some tests in our workshop using an Iconic 41E300PBUD2SM-VW dimmer. For the tests we used the PDV-100-12 and PDV-150-12, both of which performed very well. Out of the box both dimmed very smoothly to approximately 10% output. This may be able to be configured to dim lower, but this is to be confirmed. Both LED drivers had a

ADM stocks a range of high-power DALI dimmable LED drivers with PWM output from Power Source. The Power Source DD(2)V series LED drivers fill a gap in our product range, as models are available with the following power outputs: 150 Watts 200 Watts 320 Watts ADM carries both a 12V and 24V version of each, which means that we now have a DALI dimmable LED driver with PWM output for most applications. The DD2V series is DALI-2 and DALI compatible. Our stocked product range is as follows: Link to Product Information Output Voltage / Current Power Output DD2V-320-12 12V / 26.67A 320W DD2V-360-24 24V

ADM stocks a range of dimmable constant current LED drivers with selectable output current. MEAN WELL LCM Series LED Drivers The wide output voltage range of each LED driver means that they can power just a few, or many LEDs. There are three different dimming types available, in three different power output options. Dimming Types 3-in-1 Dimming DALI / Push Dimming KNX If you are looking for a LED driver for use with leading edge or trailing edge dimmers, see the Power Source PDC series LED drivers mentioned later in this blog post. 3-in 1 Dimming MEAN WELL ’s unique 3-in-1 dimming function

ADM stocks MEAN WELL constant voltage and constant current LED drivers with a built-in KNX interface. Constant Current LED Drivers with KNX Interface These LED drivers have constant current mode output, with multiple output levels selectable via a dip switch. There are 3 models in the series: These LED drivers are the first in the World to feature a built-in KNX interface, which avoids the complication of having to use a KNX-DALI gateway. All three LED drivers have an input range of 180~295VAC and selectable output current levels as detailed in the following table. Please note that the actual

Selecting a LED driver with the correct forward voltage range is critical for LED luminaire designs, and when matching a constant current LED driver to a light fitting. However, this is not always as straight forward as it seems. Firstly, LED forward voltages are not the same from die to die, there is a tolerance that is usually specified by the manufacturer. This is why ADM recommends that you do not connect LEDs to a constant current LED driver in parallel. Let’s say you have a constant current LED driver with a 1A output powering 5 LEDs with an input current rating of 200mA. Due to the

If you are using long lengths of LED strip in a project, you may find that the LED strip is brighter at one end than the other. This is caused by voltage drop across the length of the LED strip. The problem is more likely to be experienced with 12V, rather than 24V strip because you are starting with a much lower voltage (and higher currents) in the first place. All cables offer some level of resistance to electrical energy flowing through them. The longer the length of cable the greater the resistance. This includes the wire (or track) that carries the voltage along the LED strip. This means

ADM STOCKS Hytronik’s emergency lighting LED drivers. How Emergency Lighting LED Drivers Work Under normal conditions, the LED driver powers the emergency LED lights from the mains AC supply. At the same time the LED driver maintains full charge of a NiCd or NiMH battery. Should the mains power supply fail, the LED driver switches over to the battery and reduces the lux level for a regulation specified minimum length of time. On restoration of the AC power, the LED driver switches back to powering the emergency LED lightss from the mains power supply and recharges the battery. Emergency
