I wasn't able to find much about your Magnetek 6345 power converter but I was able to find out that it has a max 45 amp draw and is rated for AC/DC use which both match the Progressive Dynamics 4000 Series Inteli-Power Converter # PD4045KA. It is also important to note that this is rated for 610 watts. Since those are the main things you want to look at I do recommend using the 4000 Series over the other Progressive Dynamics converters that we carry.
Please also note that this has cutout... view full answer...
