PSU DC
4.3 Output filter (EMC filter)
The ouput filter filters the output voltage to prevent unwanted signals from
being radiated from the PSU.
4.4 Control and supervision circuits
The control and supervision circuits support:
•
•
•
The output voltage can be adjusted between 22 V to 29 V DC. The control and
supervision is achieved through an optical signal interface connector on the
front of the PSU.
