SLC 500™ Power Supplies

Publication 1746-IN004D-MU-P - May 2003

Power Supply Undervoltage Operation

SLC 500 controllers continue to operate (hold-up) for a short period of time if the
input voltage to the power supply drops below the recommended operating
voltage range. The controller continues to scan the user program and control I/O
during this time. CPU hold-up for each power supply is shown on pages

12

and 1

4

.

SLC 500 controllers turn OFF (stop scanning and disable outputs) if input voltage to
the power supply is removed or drops below the recommended operating range
for a period exceeding the CPU hold-up time. The controller resumes operation
automatically when the input voltage is restored to normal.

If the input voltage to the 1746-P7 power supply falls into a range of 4 to 9V for a
period exceeding the CPU hold-up time, the controller turns OFF and will not turn
back ON until:

•

input voltage is increased to 11V dc.
