Technical Manual
PSU side: The PSU directly outputs signals through RC
filtering.
System side: This signal is pulled down to GND through a
100-kilohm (reference value) resistor. A 100-ohm
(reference value) series resistor is connected to the
system CPLD.
The input is normal. (90 V AC < V
< V
< 300 V DC)
in
The input is abnormal (after input undervoltage
protection or input overvoltage protection).
