Power Requirements for VMIVME 7750
What are the power requirements for the VMIVME 7750?
The VMIVME-7750 requires +5V, +12V and -12V from the VME backplane. The voltage and current requirements are
Supply Current (Typical) Current (Maximum)
+5V 5.8A 7A
+12V 105mA 200mA
-12V 50mA 75mA
The VMIVME-7750 provides power to PMC site in accordance with the PMC specification. The maximum current provided on the +5V supply is 1.5A per PMC site. The maximum current provided on the +3.3V supply is 1.5A per PMC site. The +12V and -12V supplies are provided to the PMC site and to the rear-transition board (such as the ACC-0562 board). The total +12v or -12v current provided to the VMIVME-7750 (as indicated above), the PMC site and the rear-transition board must not exceed 750mA each, in accordance with the VMEbus Specification.
