Output over-voltage protection
in buffer mode
typ. 32Vdc
max. 35Vdc
In case of an internal DC-UPS 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.

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.

Touch current (leakage current)
The leakage current which is produced by the DC-UPS 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.
