UC10.241, UC10.242
UC-Series
24V, 15A, CAPACITOR-BASED BUFFER MODULES
17. PROTECTION FEATURES
Output protection Electronically protected against overload, no-load and short-circuits
*)
Output over-voltage protection
in buffer mode
typ. 32Vdc
max. 35Vdc
In case of an internal buffer module 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
For use in a controlled environment according to CSA
22.2 No 107.1-01.
Penetration protection > 3.5mm e.g. screws, small parts
Over-temperature protection included Output shuts down with automatic restart
Input over-voltage protection - Max. 35Vdc, no harm or defect of the unit
Internal input fuse included Non user replaceable
The tripping of this fuse is caused by an internal defect.
In such cases, send unit to the factory for inspection.
Internal capacitor fuse included Non user replaceable
The tripping of this fuse is caused by an internal defect.
In such cases, send unit to the factory for inspection.
Overcharging of capacitors included The capacitors are permanently monitored. In case of a
too high charging voltage, the charger will be switched
off with redundant protection measures.
Balancing of capacitors included An active balancing circuit ensures uniform capacitor
voltages. If necessary, the charging current will be
reduced to a safe value.
Failing of one or more capacitor
in the capacitor-string
included Ready contact open, moving light pattern on the three
LEDs
Temperature of capacitors included Indicated by the diagnosis LED, ready contact open
Internal errors (broken wires, …) included Charging is stopped, ready contact open, moving light
pattern on the three LEDs
*) In case of a protection event, audible noise may occur.
18. SAFETY FEATURES
Output voltage SELV IEC/EN 60950-1
PELV IEC/EN 60204-1, EN 50178, IEC 62103, IEC 60364-4-41
Max. allowed voltage between any input, output or signal pin and ground: 60Vdc or
42.4Vac. The input must be powered from a PELV or SELV power source.
Class of protection III PE (Protective Earth) connection not required
Isolation resistance
> 5MOhm
> 5MOhm
Power port to signal port
Power port / signal port to housing
Dielectric strength 500Vac
500Vac
Power port to signal port
Power port / signal port to housing
Touch current (leakage current) The leakage current which is produced by the buffer module 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 100A.
Apr. 2014 / Rev. 2.0 DS-UC10.241-EN (REVC)
All parameters are specified at 24V, 10A output current, 25°C ambient and after a 5 minutes run-in time unless otherwise noted.
