(2) Power Boost: Power or current is continuously allowed up to an ambient temperature of 45 °C (113 °F). Above 45 °C (113 °F), do
not use this power or current longer than a duty cycle of 10% and/or not longer than 1 minute every 10 minutes.

Overload behavior — Continuous current Output voltage >25V DC, see Figure 6 on page 6
—HiccupPLUS mode (3)
(3) At heavy overloads (when output voltage falls below 13V), the DC/DC converter delivers continuous output current for 2 s.
After which, the output switches off for approximately 18 s before automatically attempting a new start. The cycle repeats as
long as the overload exists. The device operates normally once the overload is cleared. See Figure 8 on page 7.
