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 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. 

Penetration protection 

> 3.5mm 

e.g. screws, small parts 

Over-temperature protection included 

Output

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.

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.
