Könner & Söhnen KS ATS 16-4/100 automatic reserve feed unit

The Könner & Söhnen KS ATS 16-4/100 automatic standby transfer switch is designed to automatically start a diesel generator and switch the load from the mains supply to the standby power source in the event of a power failure. This is a practical solution for facilities where it is essential to ensure an uninterrupted power supply without the need for constant manual monitoring.

The model operates at 230 V / 400 V and is rated for a maximum current of 100 A. The rated power is 23 kW for the 230 V mode and 55 kW for the 400 V mode. The manufacturer specifically notes that the current drawn by loads connected to the ATS system must not exceed 100 A per phase. :contentReference[oaicite:1]{index=1}

The ATS unit automatically starts the generator 10±1 seconds after the mains power fails. Thirty seconds after the generator starts, the system switches the load to the backup source. In the event of a failed start, the unit makes 3 start attempts, after which it signals an error. Once power is restored from the external mains, the delay for switching the load back is 60 seconds, and the delay for stopping the generator is 60±1 seconds. :contentReference[oaicite:2]{index=2}

This model features a SUMMER / WINTER switch, which allows for seasonal start-up conditions to be taken into account. The warm-up time for the air heating system is 0 seconds in summer mode and 15 seconds in winter mode. This helps to stabilise the start-up of the diesel generator during the cold season. :contentReference[oaicite:3]{index=3}

The front panel of the unit features a power switch, a preheating switch, an indicator for mains voltage, an output voltage indicator and a generator voltage indicator. These indicators allow for a quick assessment of the current status of the backup power system. :contentReference[oaicite:4]{index=4}
