Item
Quantity/Value
Voltage range
(all components)
-48 to -60 V battery voltage
(-40.5 V minimum, -72 V maximum)
Power feeds
2 power feeders (A, B)
Power consumption,
Circuit breakers
Release 1.0 and 2.0:
•
max. 2700 W
•
68 A circuit breakers must be used in the External Battery and Fuse
Bay (BDFB)
•
63 A circuit breakers (located on the power interfaces).
Release 2.1 and higher:
•
max. 3500 W
•
Circuit breakers
≥
125 A must be used in the External Battery and
Fuse Bay (BDFB)
•
100 A circuit breakers are part of the subracks. They are located on
the power interfaces (PI/100) and are designed to support a maximum
rated current of 100 A with a BS characteristic (medium delay). They
provide protection according to EN 60950 in the power range up to
3500 W, in particular in the range of 87.5 – 48.6 A at 40 – 72 V.
Release 6.1 and higher:
“Breaker-less” PIs (PI/100 NOCB) can be used as an option. In that case
the subrack must be protected via an external circuit breaker which can
be located in the BDFB or on a separate PDP. The current rating depends
on the configuration of the subrack.
