Mode
At heavy overloads (when output voltage falls below 13V), the DC/DC converter delivers continuous output current for 2s. After this,
the output is switched off for approx. 18s before a new start attempt is automatically performed. This cycle is repeated as long as the
overload exists. If the overload has been cleared, the device will operate normally. See Fig. 6-2.
**)
Discharge current of output capacitors is not included.
***)
The unit is featured with a “soft output regulation characteristic” in order to achieve current share between multiple DC/DC
converters, when they are connected in parallel (.g. for redundancy reasons).
