Basics of the transformer starter switch
If your fuse blows every time you switch on an appliance, the reason could be the transformer inrush current. The high inrush during the switch-on process, caused by a transformer with little or no air gap, overloads the fuse and causes it to blow. However, this problem can be effectively solved with a so-called transformer switch, also known as a TSR. The TSR is placed between the mains input and the transformer. The TSR reliably prevents the so-called “rush effect” and tripping of the fuse, as it effectively prevents the inrush current. This solution has been tried and tested for over 25 years and is used in medical devices, traffic light control systems, industrial systems, spinning machines, wire annealing systems, cathode corrosion protection current devices, power supply in test bays, point heating and mold heating as well as in many other areas.
In a special version, TSRs are also suitable for the smooth and simultaneous switching on of several switching power supplies.
