I have a question regarding the device specification.
According to the datasheet, the device consumes 600W of direct current (12Vx50A max.). This is very high and seems unusual for this device's architecture.
However, the AC power supply circuit consumption is only indicated at 286W max.
Additionally, the mention of 2 power supplies (12V / 550W each) in dual-redundant mode does not make things any clearer.
It appears there is either a typo in the DC consumption data, or the parameters are being misinterpreted.
