It is very rare that agood quality LED driver fails because of a manufacturing fault. In most cases the failure is caused by a problem with the installation, or there are some environmental factors at play.

Care should always be taken to avoid overloading your MEAN WELL power supply.

When using the MEAN WELL LCM-DA LED drivers in a Master/Slave configuration, all the slave units must be set to 100% output level.

The MEAN WELL LCM-DA LED drivers feature a push button dimming feature, as well as the DALI interface.

Not all power supplies manufactured by MEAN WELL have Australian electrical safety approvals. This is one of the reasons why not every single model of MEAN WELL power supply is listed on the Power Supplies Australia website.

Many LED drivers have either an IP67, IP66 or IP65 ingress protection rating.

The number of unapproved LED drivers coming into Australia without an RCM mark is alarming.

The MEAN WELL DR-UPS40 battery management module is used in conjunction with a MEAN WELL 24V power supply (max 40A) and a battery.

Some MEAN WELL power supplies use a fan to keep them cool during operation. Naturally, this can lead to problems with moisture and dust ingress depending on the environment in which the power supply is used.

As Power Supplies Australia mentioned in a previous blog post about MEAN WELL Power Supply’s Hiccup Mode, not all power supplies within the same series will have the same method of short circuit protection.
