The RPS1600-A supports a variety of protection features, as shown
in
Table 2 .
Table 2 Protection features of the RPS1600-A
Item Description
Input
over-voltag
e protection
When the input voltage exceeds 295 ± 5 VAC, the
unit executes an over-voltage protection shutdown
and displays an alarm through the alarm LED.
When the input voltage comes down to 275 ± 5
VAC, the unit automatically recovers and clears the
alarm.
Input
under-volta
ge
protection
When the input voltage comes down to 75 ± 5
VAC, the unit executes an under-voltage protection
shutdown and displays an alarm through the alarm
LED.
When the input voltage rises to 85 ± 5 VAC, the unit
automatically recovers and clears the alarm.
Output
over-voltag
e protection
When the output voltage exceeds –59.5 VDC, the
power module executes an over-voltage protection
shutdown and displays an alarm through the alarm
LED. To remove the fault, pull out the power module
and insert it again, or turn off the AC input and turn
it on again.
Output
over-current
protection
When the output current of a power module exceeds
31.5 ± 1.5 A, the power module executes an
over-current protection shutdown and displays an
alarm through the alarm LED. When the over-current
condition is eliminated, the power module
automatically recovers and clears the alarm.
