What Type of Output Protection is used on MEAN WELL True Sine Wave Inverters?

30 August 2021

This is a question that we were recently asked by one of our customers.

The output circuit on a MEAN WELL true sine wave inverter has a current sensor.

It will shut down electronically if it senses an over-current.

There is no fuse on the output side, but there is one on the DC input side.

The only time we seen an input fuse blown on a MEAN WELL true sine wave inverter, is when the input was connected with reverse polarity.

The inverter still worked after replacing the fuse.
