Logo! ICL230

The Logo! ICL230 inrush current limiter is used to reliably reduce inrush currents, e.g. caused
by LEDs, transformers or switched-mode power supplies as a result of the rectifier circuit at
the input with capacitor charging.
It is used for 1-phase AC line supplies with 100 V, 120 V or 230 V or for 2-phase line supplies
with 208 V rated voltage on the line side, upstream of transformers, power supplies or LEDs.
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.
