Secure independent AC supply The analog Transokraft inverters are suitable to secure uninterrupted supply to critical loads which require an AC voltage supply independent of the mains power system and the faults which may occur. This independent supply avoids interruptions to the connected loads caused by mains power failures, mains voltage deviations or mains frequency deviations, any of which may result in considerable financial costs and physical danger.

MONITORING, TESTING AND REMOTE MANAGEMENT Mains mode / test mode In this operating mode, the loads are switched over to mains supply by means of the SBS. At the same time, the loads are electrically isolated from the inverter by means of the inverter output contactor. This mode is also suitable for testing and performing measurements on the inverter without affecting the loads. This mode should be selected for an attempted restart if the inverter has switched off due to a malfunction, in order to avoid changing back to inverter mode inadvertently. There is no supply to the loads if there is...
