Product Specification for Power and Battery Cabinet
Temperature range:
-40
C - +70
C
Storage
The PBC meets the following storage requirement.
Temperature range:
-25
C - +55
C
Handling
Temperature range:
-40
C - +70
C
The PBC is designed to be placed on the ground.
In addition to this requirement the PBC will endure a topple. Minor
damages to the cabinet, for example a broken corner of a cooling fin
after a topple, will not disturb the function of the PBC.
6.7.8
Climate Protection
Climate Protection Principle
The climate protection maintains the internal temperature within
allowed range for the units in the PBC.
The climate protection of the PBC is handled by a combination of:
•
Natural convection using cooling fins
•
Conductional heating
Battery Heating Capacity
The system delivers DC to the external users independent of
temperature.
The system has the capacity to heat the batteries from
−
33
C to start
charging within 30 minutes (15 minutes from
−
15
C) if the
environmental conditions are no wind.
The above applies if the environmental conditions are: no wind or
accumulated ice or snow on the PBC.
During back-up mode the heater is not operational.
Ingression
The PBC fulfils the IP-55 requirements according to the standard IEC
529 and type 3R according to UL50.
6.7.9
Power Supply
Input Supply Voltage
The PBC can be connected to mains supply voltage with Nominal:
EN/LZT 123 2697
