    Hallo,
    I've a problem with my ZYT90-155-12 and sabertooth. Actualy I use a server PSU 1400w 90A but always shutting down in peak protection. Do you think this might solve my problem?

    LED PSUs are not as sensitive as server PSUs, so it may well be a better option as long as you have ruled out other possible triggers.

    Thanks Noorbeast for your reply.

    Do you know the led PSU S-1200-12 100A?

    In my firt sim with zyt73 motors and jrk I used s-600-12 50A. It was a good solution even if this psu has no protection fuse and I happened to burn more than one caused regenerative current from motor.

    Now my new sim will have zyt90-155-12 motors (40A peak) and sabertooth 2x32 card. For this configuration I need a Psu 12V-100A
    The options are use n.2 S-600-12 50A in parallel, but I don't know how connect and what is necessary to avoid problem, shortcircuit and also
    The other option should be S-1200-12 100A but I don't know anyone tha used this psu

    Actually I tested ZYT90-155-12 and sabertooth 2X32 with a server PSU IBM 1400W 90A but it's always in peak protection. I also tried to apply 1 than 2 than 3 than 4 resistor for voltage clamp but the problem not solved.
    As i don't like the idea to put battery I prefer value the option of led psu


    S-600-12 50A not have a fuse protection and I don't know if S-1200-12 100A have a fuse. If not How can I do o avoid that regenerative current from motor burn the psu?
    Thanks for support
