1.8.1.1 Architecture of the Power Supply System
The ME60-X3 supports either DC or AC power supply.
Power modules convert the input voltage into -48 V DC voltage to supply power for the entire
system. The power supply system has the following features:
The power supply system consists of two AC power modules or two DC power modules
working in 1+1 backup mode.
Both AC power modules and DC power modules support alarm functions. DC power
modules support I
2
C communications and AC power modules support RS485
communications.
Two AC power modules or two DC power modules work in 1+1 backup mode to improve the
reliability of power supply. Figure 1-25 shows the power supply system.
