The TSRLF is a control unit for controlling an external actuator for setting up a transformer switching relay. It enables fast switching and switching of high-power single-phase transformers. External thyristors or solid state relays act as actuators.
The connected actuator is controlled via the soft switch-on method so that one or more single-phase transformers can be operated in no-load or under load without an inrush current. For example, welding transformers with rated currents above 32 A.
| Mains voltages | 110, 230, 400, 500 V and various wide voltage ranges |
|---|---|
| Ext. actuator | Solid state relays 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 |
