Using your M2-atx computer power supply in a 24 volt marine / boat installation

Fiberoptic · 01-22-2009, 01:00 PM

I have a few questions about marine 24 volt systems. I thought the answers might be beneficial to others, so I will be posting both my questions and the answers here in this thread.

What is the spike /peak voltage that should be expected in a 24 volt marine or boat environment?
According to the spec sheet, clamping will occur at 25-27 volts. What is the exact failure behavior when input voltage exceeds 25-27 volts?
How long can the voltage exceed 25-27 volts before clamping occurs?
Is there more or less heat generated when operating in 24volts mode vs. 12 volts?
At what input voltage will permanent damage occur to the unit?

Try M2-ATX-HV, it can handle up to 32V (Actually will work up to 35V!)
