Rockwell Automation Allen-Bradley 1606-XLE120E - Output

Rockwell Automation Publication 1606-RM100A-EN-P - July 2020 9
Power Supply - 24V, 5 A, 120 W, Single-phase Input Reference Manual
Output The output provides a SELV/PELV rated voltage, which is galvanically isolated
from the input voltage.
The output is designed to supply any kind of loads, including capacitive and
inductive loads. If extreme large capacitors, such as EDLCs (electric double
layer capacitors or ‘Ultra Caps’) with a capacitance > 0.3 F are connected to the
output, the unit can charge the capacitor in an intermittent mode.
The output is electronically protected against overload, no-load, and
short-circuits. If there is a protection event, audible noise can occur.

This is the maximum output voltage that can occur at the clockwise end position of the
potentiometer due to tolerances. It is not a guaranteed value that can be achieved

Fuse breaking current Typ 15 A
Up to 12 ms once every 5 seconds, see
Figure 9. The fuse braking current is an enhanced
transient current that helps to trip fuses on faulty output branches. The output voltage stays
above 20V.

The unit is resistant and does not show malfunctioning when a load feeds back voltage to the
power supply. It does not matter whether the power supply is on or off. The absorbing energy
can be calculated according to the built-in large sized output capacitor.
(1) This current is also available for temperatures up to +70°C (+158 °F) with a duty cycle of 10% and/ or not longer than 1 minute every 10 minutes.
(2) At heavy overloads (when output voltage falls below 13V), the power supply delivers continuous output current for 1s. After this, the output is switched off for approx. 9s before a new start
attempt is automatically performed. This cycle is repeated as long as the overload exists. If the overload has been cleared, the device will operate normally. See Figure 10
