Power Supply Unit module
There are four PSU modules in the bullx blade system, each of 2900W rating. These take
in the AC input of 180VAC to 264VAC and provide 12V main and 3.3V standby outputs.
The four PSU modules provide N+1 redundancy. The typical system power dissipation is
around 7900W depending on the configuration and the customer’s applications. The PSU
modules occupy the rear of the bullx blade system.
The high-level features of the PSU module are as below:
