Plug-in Power Supply Card 120 Vac /-24 Vdc
or 130 Vdc/-24 Vdc

The plug-in power supply card 751313MC provides 120 Vac or 130 Vdc to -24 Vdc power to the 5-card Shelf or the 8-card Shelf. It also offers the possibility of recharging the Plug-in Battery Backup Card, Model 751312.

If the plug-in battery backup card is not used, then two plug-in power supply cards may be installed in the 5- or 8-card Teleline shelf for redundancy. Each card is capable of providing the power required by a fully loaded shelf. When two cards are available, the load is shared by the two cards. If one of them fails, the other one takes over the full load without interruption of power.

  • The card can be used in conjunction with the Plug-in Battery Backup card, Model 751312, to provide an uninterruptible power supply when working from 120 Vac
  • A “Power In” LED and a “Power Out” LED allow easy assessment of power supply functionality
