The TSRLF is a control unit for an external control element to arrange a transformer switching relay. It is usable for fast switsching and to switch single-phase transformer with high power. External thyristors or semiconductor relays are used as control elements. Using the soft starting procedure, the connected control element is actuated in a way that one or several single-phase transformers can be operated in no-load operation or under load without an inrush current. This can be used for welding transformer with more than 32 A, for example.
| Mains voltage | 110, 230, 400, 500 V and various wide voltage ranges |
|---|---|
| External control element | Semiconductor relay or thyristors |
| Control input | for normally open contact and control voltage |
| Control output | with or without control output |
| Design | circuit board, housing with or without standard rail holder |
