the power part must be designed in hot backup mode, and two
power supply modes of -48V DC and 220V AC are designed.
Load sharing is adopted for the master/slave power supply
module working in normal state. When a power supply becomes
faulty, the other module will supply the system with the power
for normal operation. Figure 29 shows the power supply of
ZXR10 GER.
