3.3kW Bidirectional On-Board Charger
CTS1060 series integrated AC-DC module supports both battery charging and DC-to-AC inverter operation (V2G / V2L). Automotive-grade modular design with up to 8 units parallel for scalable power.
Two-Way Power: Charge or Invert
The CTS1060 is a true bidirectional power conversion module. In charging mode, it converts grid AC to DC for battery charging. In inverter mode, it feeds battery DC back to AC — enabling V2G (vehicle-to-grid), V2L (vehicle-to-load), and emergency backup power applications.
Up to 8 identical units can operate in parallel without a master controller, giving you scalable power from 3.3kW up to 26.4kW in the same compact form factor.
Automotive-Grade Modular Power Conversion
The CTS1060 series is an integrated 3.3kW bidirectional on-board charger module built on a fully digital soft-switching control platform. Designed for space-constrained vehicle installations with bottom-cooling IP67 architecture.
Built on a fully digital soft-switching control architecture, the module achieves high efficiency across the full load range while maintaining low electromagnetic interference.
Bootloader support and background debugging allow firmware updates and parameter tuning in the field — no hardware modification required.
