Sometime ago MEAN WELL commenced the process of phasing out the SP series power supplies and has since added all models to the discontinuation list.
MEAN WELL has a wide range of LED drivers that are dimmable via a DALI controller.
You really don’t need to pay the best part of $1000 just to get a power supply that can charge a battery, switch over to the battery if the AC fails and trigger an alarm if the battery is getting low.
In some of the MEAN WELL LED driver data sheets you will come across the description “Constant Voltage + Constant Current mode output”.
Customers are advised that there is to be a change to the style of labels used on certain models of MEAN WELL LED drivers.
A single DALI system has 64 static addresses that can be used to control devices, such as DALI dimmable LED drivers.
Fan-cooled power supplies may fail if used in outdoor LED signage.
Over the last couple of years MEAN WELL has introduced several new models of power supplies right across the range.
Connecting multiple LEDs to a constant current LED driver in parallel is not recommended.
