The Könner & Söhnen KS 48VS-DC DC generator is a specialized gasoline/gas generator for charging 48V battery systems, built to work with hybrid inverters, backup power systems, and autonomous energy complexes. The model provides stable DC output voltage, automatic start and efficient battery charging without the need for additional AC/DC chargers.
Key advantages of KS 48VS-DC
- Direct charging of 48V battery systems without additional converters
- Automatic AUTO operation mode with start when battery voltage drops
- Nominal power 3.3 kW and charging current up to 60 A
- Stable IUo charging characteristic for correct charging of LiFePO4 and other batteries
- External control via dry contacts (EXTERNAL CONTROL)
- Compact dimensions and transport wheels for mobile use
Technological features
- Works with 48V systems — support for ranges of 47-52 V, 48-54 V or 50-55 V depending on the version
- Automatic start when the lower battery voltage threshold is reached
- Charging with constant current up to 60-63 A with subsequent transition to voltage stabilization mode
- LED display with display of output voltage and current
- Support for external control via dry contacts of inverters, BMS or UPS
- 4-stroke gasoline/gas engine KS 240i with a power of 7.5 hp.
