F 7126: Power supply module
Input voltage 24 VDC, output voltage 5 VDC
for PES H51q
Figure 1: F 7126 power supply module
The module supplies automation systems with 5 VDC from a main supply of 24 VDC. It is a
DC/DC converter with safe isolation between input and output voltage. The module is equipped
with overvoltage protection and current limitation. The output is short-circuit-proof.
To avoid unbalanced load with redundant use of the power supply F 7126 the difference be-
tween their output voltages may not be more than 0.025 V.
On the front plate there are a test socket and a potentiometer for adjusting the output voltage.
The adjustment is only admissible with a suitable measuring instrument of high accuracy.
