Könner & Söhnen Automatic Transfer Switch KS ATS 4/63HD
- Automatically starts a compatible diesel generator and transfers the connected load when mains power fails.
- Up to 63A automatic transfer capacity for 230V single-phase or 400V three-phase standby-power systems.
- Designed for Könner & Söhnen diesel generators with the ATSR designation and ATS connector - KS 8100HDE-1/3 ATSR, KS 8200HDES-1/3 ATSR, KS 9100HDE-1/3 ATSR, KS 9200HDES-1/3 ATSR (EURO 5), KS 9300DE ATSR, KS 9300DE-1/3 ATSR generators.
Automatic mains-failure backup for ATSR diesel generators
The Könner & Söhnen KS ATS 4/63HD is an automatic transfer switch for compatible diesel generators with an ATSR connection. It monitors the mains supply, starts the generator after a power failure and transfers the selected load to generator power.
When mains power returns, the ATS transfers the load back and stops the generator after the configured delay. The integrated programmable logic controller supports automatic or manual operation and configurable timing for the standby sequence.
Key features
- Matched diesel-generator compatibility: suitable for Könner & Söhnen diesel generators with “ATSR” in the model designation.
- 63A transfer rating: supports 230V single-phase or 400V three-phase system configurations, subject to generator and installation design.
- Programmable automatic control: adjust the mains-failure start delay, generator warm-up time and other transfer timings.
- Manual and automatic modes: enables normal standby operation as well as testing and controlled maintenance.
- Generator support and status indication: includes built-in 12V battery charging, emergency stop, control cable and operating-status indicators.
Where to use
Use the KS ATS 4/63HD for automatic standby-power systems at homes, farms, workshops, commercial premises, depots and remote facilities using an ATSR-compatible Könner & Söhnen diesel generator. It is suited to essential-load distribution boards rather than uncontrolled connection of an entire site.
The generator’s selected output mode determines the backup arrangement. For generators with 230V/400V voltage-selection capability, the electrician must design the ATS and load circuits for the chosen operating mode; do not assume a single generator can support all single-phase and three-phase loads simultaneously.
This product requires professional installation and commissioning. Energian can provide UK expert support and help arrange installation through trusted partners for generator compatibility, earthing, protection, cable sizing and essential-load design.
