  • Supports displaying four or two power inputs.
  • Supports detecting the voltage of four or two -48 V/-60 V inputs.
  • Supports detecting 10 channels of external boolean parameters (including one channel of water sensor parameters, door status and MDF).
  • Supports detecting 4 external analog parameters (including temperature, humidity and two channels of reserved parameters).

Power Distribution Principle

Figure 6-2 shows the power distribution principle of the I-type DC PDU.
