The KS 15-1E 1/3 ATSR generator model features unique VTS phase switching technology, allowing it to operate in single-phase (230V) or three-phase (400V) mode with almost identical power output.
Convenient, ergonomic control panel with an emergency stop button and a multi-function LED display that allows monitoring of generator operation — voltage, frequency, and hours worked.
Each model is equipped with sockets that allow drawing maximum power from the device; the sockets are fitted with fuses and come with appropriate plugs.
A spacious 55-liter fuel tank ensures long and continuous operation. The powerful air-cooled twin-cylinder engine (22 hp) meets all European quality standards, including the modern EURO-V standard.
Each engine has an individual serial number, allowing for quality control of manufacturing and service. The unique innovative VTS (Voltage Transfer Switch) phase switching system provides almost identical power for single-phase (230V) and three-phase (400V) consumers.
Each mode has its own circuit breaker. The convenient ergonomic control panel allows easy operation of the entire device and requires no additional skills; it is equipped with sockets designed to draw maximum generator power, an LED display, and an emergency stop button. The generator can be connected to an ATS (automatic transfer switch) unit.
The ATS output has an 8-pin connector. TM "Konner & Sohnen" generators are equipped with a high-quality synchronous alternator with 100% copper winding.
Only copper winding can withstand maximum loads without damage, ensuring long-term reliable operation of the generator set. "Konner & Sohnen" generators are equipped with an enlarged steel fuel tank (55 L), which extends the generator's operating time without refueling.
A fuel level indicator is located on the tank for ease of use.
