Purpose-built for the Könner & Söhnen KS 5500iES ATSR, KS 5500iEG inverter generators with its 7-pin ATS connector. Provides automatic or manual operation, battery charging and an emergency generator-stop button. Automatic backup power for compatible inverter generators The Könner & Söhnen KS ATS 4/25 Inverter is an automatic transfer switch for creating an automatic standby-power arrangement with the KS 5500iES ATSR inverter generator. It monitors the mains supply, starts the generator after a power failure and transfers the connected load once generator power is available. When mains power is restored, the unit transfers the load back and stops the generator automatically. A built-in PLC allows the generator start delay and warm-up time before load connection to be programmed. Key features Matched compatibility: designed for the KS 5500iES ATSR inverter generator with an integrated 7-pin ATS connector. Automatic mains-failure response: starts the generator and transfers the load during a mains outage; returns the load when mains power is restored. Manual or automatic operation: select the operating mode to suit commissioning, testing or normal standby operation. Generator protection functions: emergency-stop button, error indication and up to five automatic start attempts if the first start is unsuccessful. Battery support: built-in 12V battery charging supply with a maximum charging current of 2A. Where to use Use this Könner & Söhnen automatic transfer switch with a compatible KS 5500iES ATSR generator for essential single-phase loads in homes, small offices, workshops, telecoms equipment or remote sites. The total connected load must remain within the ATS and generator ratings. The KS ATS 4/25 Inverter can be connected to single-phase or three-phase mains networks, but the connected generator determines the available generator supply. The KS 5500iES ATSR is a single-phase generator; this ATS does not make it a three-phase generator. This is not a plug-and-play building connection. Mains connection, earthing, protective devices, cable sizing and commissioning must be completed by a qualified electrician. Energian can help arrange installation through trusted UK partners.
