Mp40 power supply

[Piece of reef]

Hey guys so i have a mp40 qd and the power supply makes a whizzing sound or buzzing, very light, it still works but just want to prepare for the worst

Now ive been reading alot and got some picture of other peoples mp40s, why is some quiet drives 24v and some are quiet drives 32v power supplys ?

My one is 32v but being in australia im finding it very difficult to find a replacement

Am i able to use a 24v if necessary

This is the one is have at the moment

This will work. I had a flood and my MP power supplies were a victim. I bought these are they work great!
