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.
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.
One of Australia’s top universities wanted to update their lighting to LED and to control it with an existing DALI system. The difficulty was that no access was permitted to the roof space.
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.
