The device is featured with a “soft output regulation characteristic” in order to
achieve current share between multiple devices, when they are connected in parallel.
The “soft output regulation characteristic” regulates the output voltage in such a
manner that the voltage at no load is approx. 4% higher than at nominal load.

PowerBoost
This power/ current is continuously allowed up to an ambient temperature of 45°C.
Above 45°C, do not use this power/ current longer than a duty cycle of 10% and/ or not longer than 1 minute every 10 minutes.

Mode
At heavy overloads (when output voltage falls below 13V), the power supply 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.
