E11 Behaviour in case of exceeding maximum backup time
When the given buffering times are exceeded, the output is separated on the basis of the discharge voltage of
the corresponding storage medium (total discharge protection).
For supercapacitors, which are not sensitive to a deep discharge, a threshold has been definded which is limi-
ted by the current. The lower the voltage, the higher the current on the capacitors at constant output power.
If more than 70 % of the maximum allowable output current is consumed during discharge of the supercapa-
citors, the converter will shut down without immediately dis connecting the output and a lower voltage will
appear at the output (state <2 s). This condition should be avoided by shutting down the system in time before
discharging the supercapacitors under high currents.
