Power Boost

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.

**)

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. 6-3.

***)

Discharge current of output capacitors is not included.

****)

This is the maximum output voltage which can occur at the clockwise end position of the potentiometer due to tolerances. It is not

guaranteed value which can be achieved. The typical value is about 28.5V (in “single use” mode).
