ICEpower 80AM2

[mga2009]

Hi,

I have a bunch of ICEpower 80AM2 amplifiers. These are 2x80W or 1x160W BTL.

They don't have an integrated PSU as they work with the ICEpower 400SM power supply, that can power 8x 80AM2 amplifiers.

The 400SM power supply is expensive around USD$180 so I am looking for cheaper alternatives. AFAIK these amplifiers run on a dual +/-36volts power supply.

Do you think it might work? Do you have any recommendations on power supplies? What about some Hifime SMPS300RE?? (IDK if its better price wise). Maybe some Meanwell?

Looking forward to your suggestions!

Cheers.

Lowest cost alternative might be to use two 36v single rail supplies and connect them in series. Something like these for example, pick 36v and 2A units qnty 2. About $35 shipping included. If you get the 5A ones the price will be about $100 for two.

I bought 2 Meanwell LRS 200-36. Is there a simple way to get a +36V rail? and a -36V rail?

Also, considering the amps are 160W, is it OK If I use 2x 100W psu?

Yes, that works as long as the chassis ground/protective earth of the PSU’s are isolated from output voltages.
