Power Requirements for VMIVME 7750


Description

What are the power requirements for the VMIVME 7750?

Resolution

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.
