Choosing a suitable LED driver for your lighting needs can be a tedious and confusing undertaking due to a great number of choices available in the market.

This is a question we were recently asked by one of our customers, who had initially selected a MEAN WELL LDB-L DC to DC LED driver for use in a 12-volt solar/battery off-grid setup.

We sometimes take calls from customers with a MEAN WELL battery charger in their caravan, which does not show a light when it is powered up.

The MEAN WELL A300 series modified sine wave inverter gives you a remarkable level of functionality at a low cost.

When a LED light fails the presumption that is often made is that the LED driver has failed.

We were contacted by a customer wanting to use the MEAN WELL DDR-120B-48 to convert a 24V source to power a 30W, 48V power injector for another piece of equipment.

Some applications require an inverter that can accept a negative (–v) voltage input.

A customer contacted Power Supplies Australia, who was working on a project with LED luminaires, which were powered by 2 x MEAN WELL ELG-240-C1050DA LED drivers.

Power Supplies Australia was recently contacted by a customer who wanted to know if he could connect the negative output of a MEAN WELL MPM series power supply to earth ground?

You may have noticed that in the data sheets of some MEAN WELL battery chargers it states that the charger can be used for Lithium-ion batteries, and to contact MEAN WELL for further information.
