Inrush current limiter
■
Overview
The SITOP inrush current limiter is used to reliably reduce the
starting currents that are caused, for example, by transformers
or with pulse-controlled power supplies by the rectifier circuit on
the input side with capacitor charging.
In 1-phase AC networks, it is supplied with rated voltages of
100 V, 120 V or 230 V and in 2-phase and 3-phase AC networks
with rated voltages of 208 V to 480 V on the line side upstream
of transformers or power supplies and it limits the inrush current
independent of temperature, for example, up to 10 A at 230 V by
means of an installed fixed resistor. In static operation, the limit
resistance is bypassed after approx. 120 ms to reduce the
power losses generated.
