Overload capability

Peak current duty cycle with previous load (300 % overload)

Note:

I_max stands for 2 ? I_rated in the following overload characteristics.

Duty cycle with previous load

Duty cycle without previous load

S6 duty cycle with previous load with a duty cycle duration of 600 s

S6 duty cycle with previous load with a duty cycle duration of 60 s

Duty cycle with 60 s overload with a duty cycle duration of 300 s

Duty cycle with 30 s overload with a duty cycle duration of 300 s

Derating characteristics

Output current as a function of pulse frequency

Output current as a function of ambient temperature

Current derating as a function of output frequency

Installation altitude
