Specification

Nominal power, kW: 3.3
Engine start: Automatic and Manual/External
Voltage, V: max 54.5 ± 0.5

Benefits

  • Backup charging device – designed for battery-based power systems with an operating voltage range including 50–55V.
  • Automatic operation – in AUTO mode, the generator independently monitors the battery voltage, starts when it drops below 50V, and stops when the output reaches 54.5 ± 0.5 V and the current drops below 20A.
  • MANUAL/EXTERNAL mode – generator starts/stops via CONTROL TERMINAL contacts, regardless of battery voltage or output current.
  • Indicator system – allows for quick monitoring of operating status and important parameters.
  • Transport kit – the generator is equipped with a foldable handle and wheels for convenient transport, significantly expanding its application possibilities.
  • This model is compatible for Tandem Power Technology and pairs with KS 5200PS
