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.

We were asked by a customer that uses MEAN WELL power supplies in many of their products if they needed to fuse the negative output cable in a 24VDC floating power supply, and if so why?

Power Supplies Australia was recently contacted by a customer wiring 4 MEAN WELL 24V 180W LED drivers with 3-in-1 dimming to a commonly used lighting control system to power the RGBW LED strip.

We were contacted by a customer, who had a MEAN WELL PB-600 series battery charger in his caravan.

We recently had a customer ask if we recommend earthing the 0VDC from the V- DC output terminal of MEAN WELL DIN rail power supplies. Or, would we recommend leaving the DC output floating, so it is isolated from protected earth?

Power Supplies Australia stocks the MEAN WELL DDRH series of DIN rail DC to DC converters with a wide input voltage range of 150~1500VDC late April.

True Sine Wave inverters are sometimes referred to as Pure Sine Wave inverters.
