Power Requirements in a DC Environment
A Direct Current environment must supply four feeds from the customer's power
source. Each frame containing Tekelec products requires that power be provided
from one to four breakers at –48VDC.
Each frame is divided into A and B power buses. In the event of loss of power on
one of the buses, the other bus must be able to supply current for the entire frame.
Therefore, each bus requires wiring sized to handle up to the maximum amps at
–48VDC, with a maximum voltage drop of 0.6 volts. This requirement is met
automatically when power is supplied by breakers.
NOTE: If breakers are tripped by an overload, they must be switched
completely OFF and then ON to reset.
The following table contains detailed information on T1100 AS power
requirements in a DC environment: PowerReqmts.pdf,
