Power Supply Unit (PSU)
The PSU rectifies AC supply voltage to regulated system voltage, +24 VDC.
The PSU’s are connected in parallel at the secondary side and may be configured with an
N+1 redundancy.
When using a battery backup, an extra PSU is recommended for recharging of batteries. If
the RBS is equipped with a redundant PSU no extra PSU is required for battery charging.
