Subrack specifications
Quantity/Value
–48 to –60 V battery voltage
(–40.5 V minimum, –72 V maximum)
2 power feeders (A, B)
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 E 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 OCB) 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.
Maximum 51 kg [112.46 lbs]
