Inrush current limiter

Logo! ICL230

The inrush current limiter is connected between the line supply and the power supply to be
supplied. It is suitable for connection to 1-phase AC line supplies with 100 V, 120 V or 230 V
50-60 Hz or to 2-phase line supplies with 208 V line voltage on the line side, upstream of
transformers, power supplies or LEDs, and using the integrated fixed resistor, it limits the
inrush current to approx. 10 A at 230 V. In steady-state operation, the limiting resistor is
bypassed after approx. 60 ms, therefore minimizing the associated power loss.

SITOP inrush current limiter

The inrush current limiter is connected between the line supply and the power supply to be
supplied. It is suitable for connection to 1-phase AC line supplies with 100 V, 120 V or 230 V
50-60 Hz or to 2-phase or 3-phase 208 - 480 V AC line supplies. The switch-on current pulse
at 230 V is limited to approximately 8 A. In steady-state operation, the limiting element is
bypassed.
