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
