Rockwell Automation Allen-Bradley 1606-XLE120E - Hold-up Time; DC OK Relay Contact

10 Rockwell Automation Publication 1606-RM100A-EN-P - July 2020
Power Supply - 24V, 5 A, 120 W, Single-phase Input Reference Manual
Hold-up Time The hold-up time is the time during which a power supply’s output voltage
remains within specification following the loss of input power. The hold-up
time is output load dependent. At no load, the hold-up time can be up to
several seconds. The green DC OK lamp is also on during this time
.
DC OK Relay Contact This feature monitors the output voltage on the output terminals of a running
power supply.

Contact closes As soon as the output voltage reaches Typ 90% of the adjusted output voltage level.
Contact opens
As soon as the output voltage dips more than 10% below the adjusted output voltage.
Short dips will be extended to a signal length of 100 ms. Dips shorter than 1 ms will be
ignored.
Switching hysteresis Typically 0.7V
