CONNECTING ANCILLARY EQUIPMENT TO THE PSU
The Ancillary equipment to be powered by the power supply should be fitted to the power supply output
connections. Note that the PSU has 2 outputs labeled 24V A and 24V B, each fused at half the total output.
If the application requires current more than
one output can supply, then both outputs
should be used. The Positives should be
commoned together as shown. . The
Negatives are already commoned on the
controller PCB so do not need to be
commoned externally.
Connect to a single output if the maximum
current is less than half the maximum rated
output of the power supply.
Two separate loads can be powered
separately by using the both output
channels.
The Fault Relay is used to communicate the
status of the PSU to ancillary equipment.
The relay is normally energized, so that it
can signal a fault in the event of total power
failure.
The NO terminal (red wire) is connected to
the Common terminal (yellow wire) in the
system normal condition.
