Protection Features
Letter Description
A Input terminals - (screw terminals)
N, L - Line input
PE - Protective earth input
B Output terminals - (screw terminals, two pins per pole)
+ Positive output
– Negative (return) output
C Output voltage potentiometer -
Guaranteed adjustment range: 24…28V
Factory set: 24.1V
D DC-OK status indicator- (green) On, when the output voltage is >18V
E DC-OK Relay Contact (push-in terminals)
Attribute 1606-XLB120E
Output protection Electronically protected against overload, no-load, and short circuits
Output overvoltage protection typ 31V DC
max 34V DC
In case of an internal power supply anomaly, a redundant
circuit limits the maximum output voltage. In such a
case, the output shuts down and stays down until the
input voltage is turned off and on again for at least 1
minute or until the green status indicator went off.
Degree of protection IP 20 EN/IEC 60529 Caution: For use in a controlled
environment according to CSA 22.2 No 107.1-01.
Over-temperature protection
no
Input transient protection MOV (Metal Oxide Varistor)
Internal input fuse Included not user replaceable
