Power
requirements
The power requirements of cabinets depends on the configuration.
Power consumption (dc and ac)
Table 2-5 lists typical and maximum power consumption values.
Table 2-5 Power consumption of full cabinet, including digital redundancy
and external battery charging
Typical measured consumption Maximum power consumption
2200 W 5600 W
NOTE Maximum power consumption figures are theoretical
values derived under extreme conditions and are affected
by variables such as temperature, component tolerances,
transmission power and supply voltage. Although these
figures must be considered when planning site power
requirements, typical measured consumption values will
be lower.
Cabinet input power supply requirements
WARNING All cabinets and supply cables must be protected by an
upstream fuse or circuit breaker.
Table 2-6 lists the power supply requirements for the different power supply
options.
