Hi, I could not find the schematic diagram for this power supply. This Schroff maxpower MAX180 PSU is working fine.
I need the spec of the Melf diode to use in a custom-made Schroff maxpower MAX180 PSU for special broadcast equipment. The only difference is the output sensing circuit and both + / - sense circuits were internally connected with one Melf diode and jumper resistor.
The radio audio routing equipment manufacturer does not want to sell us this new PSU and has not authorized us to purchase a custom-made PSU from the Schroff. Schroff could not sell us a custom-made PSU without an authorized letter from the equipment manufacturer. This equipment manufacturer wants us and forces us to spend millions of dollars to upgrade to their new system but we refuse due to budget costing.
So, I have bought a similar maxpower MAX180 PSU from Schroff. I want to modify the output sensing circuit according to the custom-made Schroff maxpower MAX180 PSU design.
At the custom-made Schroff maxpower MAX180 PSU, I measured both ends were short circuits with a Melf diode on the pcb board sense circuit. So, I believe this Melf diode works as a protection circuit and only allows current flow in one direction or purpose as a surge protection.
I really hope an expert could give me advice on this matter. What would happen if I did not put this Melf diode on the custom-made Schroff maxpower MAX180 PSU?
