TSR BaseLine

When transformers are switched on, extreme inrush currents often occur – with potential consequences such as tripped fuses, overloaded components or, in the worst case, a fire hazard. This does not have to be the case. 

The new TSR BaseLine from FSM is the compact, economical solution for transformer manufacturers and industry when it comes to switching single-phase transformers and switching power supplies reliably, wear-free, and without inrush current – even with frequent switching under load.

• No inrush current – protects components, prevents tripping, and increases operational safety
• Smooth switching on thanks to electronic pre-magnetization
• Compact design for flexible integration
• Can be used with toroidal and laminated core transformers as well as switching power supplies
• Maintenance-free & durable – up to 10 million switching cycles
• Ideal for industry, test benches, audio, and lighting applications

With the TSR BaseLine, you are choosing maximum operational reliability, easy mounting on the DIN rail, and a solution that works reliably in the long term – developed and manufactured in Germany.
