Guaranteed value
Max. 58.0V
This is the maximum output voltage which can occur
at the clockwise end position of the potentiometer
due to tolerances. It is not a guaranteed value which
can be achieved.

For minimal 12ms once every five seconds,
see Figure 8.2.
The output voltage stays above 40V.
See chapter 26.1 for more peak current
measurements. For AC 100V mains, the pulse length
is shorter than 12ms.

1
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.
2
Hiccup mode
At heavy overloads (when output voltage falls below 26V), 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 Figure 8.3

Discharge current of output capacitors is not included.
