CPS20.481-D1
C-Series
48V, 10A, DC/DC CONVERTER
16. PROTECTION FEATURES
Output protection Electronically protected against overload, no-load and short-circuits
*)
Output over-voltage protection typ. 58.5Vdc
max. 60Vdc
In case of an internal DC/DC converter defect, a
redundant circuit limits the maximum output voltage.
The output shuts down and automatically attempts to
restart.
Degree of protection IP 20 EN/IEC 60529
Caution: For use in a controlled environment according
to CSA 22.2 No 107.1-01.
Penetration protection > 5mm e.g. screws, small parts
Over-temperature protection yes Output shut-down with automatic restart
Input transient protection MOV (Metal Oxide Varistor)
Internal input fuse DC suitable fuse included not user replaceable
Reverse input polarity protection yes unit does not start, no signalling
*) In case of a protection event, audible noise may occur.
17. SAFETY FEATURES
Input / output separation

SELV IEC/EN 60950-1
PELV IEC/EN 60204-1, EN 50178, IEC 62103, IEC 60364-4-41
double or reinforced insulation
Class of protection I PE (Protective Earth) connection required
Isolation resistance > 5MOhm input to output, 500Vdc
PE resistance < 0.1Ohm
Touch current (leakage current) The leakage current which is produced by the DC/DC converter itself depends on the
input voltage ripple and need to be investigated in the final application.
For a smooth DC input voltage, the produced leakage current is less than 100μA.
