The MEAN WELL HLG 'B' & 'AB' series, and ELG ‘B’ & 'AB' series LED drivers utilise a common dimming method, where the amplitude of the current fed to the LEDs is varied.
When talking about LED drivers most people would automatically think of the type that takes AC power and converts it to either a constant DC voltage, or a DC voltage maintained at a constant current.
In some parts of Australia power lines are injected with a ripple voltage, or pulse. This can be at a frequency ranging from 167Hz to 1050Hz and is also known as the Zellweger ripple or audio frequency injection control (AFIC).
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.
Many of our readers will already know that ADM has a strong commitment to educating our customers and the wider community about the importance of electrical safety approvals.
Some of the MEAN WELL’s HLG series LED drivers have a particular characteristic, which can be problematic for installations with poor quality light fittings or LED strip.
We have had some customers experiencing difficulties when trying to dim MR16 globes with a dimmable LED driver. Many MR16 globes on the market have been designed to be used as a replacement to a halogen globe in an existing light fitting.
