Product overview
Introduction
The RPS1600-A is an external power supply that uses AC inputs and
provides eight lines of DC output, with a maximum output power of
3200 W (220 VAC input voltage) and 1600 W (110 VAC input voltage).
It can provide DC power supply simultaneously for multiple powered
devices (PDs), such as switches and routers. The RPS1600-A can serve
as:
• A heavy-duty external PoE power supply
• A redundant power supply for PDs
Serving as a redundant power supply, the RPS1600-A offers the
following functions:
• If using the same AC power source with a PD, when the internal
power supply system of the PD fails, the RPS1600-A can provide
DC power supply to the PD, ensuring uninterrupted operation of
the PD.
• If using a different AC power source from the PD, when the AC
power source to the PD fails, the RPS1600-A can provide DC
power supply to the PD, ensuring uninterrupted operation of the
PD.
The RPS1600-A adopts a power supply failover mechanism: when the
power supply of the PD works properly, both the RPS1600-A and the
PD’s power supply can supply power to implement load sharing; when
the power supply of the PD fails, only the RPS1600-A works to ensure
uninterrupted operation of the PD.
