High-Power DC-DC Voltage Conversion for 12V Systems

Converts power from a higher-voltage DC electrical system to a stable lower-voltage DC output for auxiliary equipment, battery systems and other onboard electrical loads. The non-isolated architecture supports high-current applications, while adjustable output allows the converter to be configured for different system requirements. A remote on/off connection also allows the converter to be controlled without placing a high-current switch in the main input wiring.

Key Features

  • Adjustable Output: Output voltage can be adjusted to suit the connected electrical system or battery charging requirements.
  • Battery Charging Capability: Adjustable output allows the converter to be configured for buffer-charging a compatible battery.
  • Parallel Operation: Multiple converters can be connected in parallel when additional output capacity is required.
  • Remote On/Off: Supports control using a low-power switch or engine run/stop switch, eliminating the need for a high-current switch in the input wiring.
  • Temperature-Controlled Cooling: Fan-assisted cooling manages operating temperature during higher-load applications.
  • Secure Power Connections: Heavy-duty bolt connections provide a robust interface for high-current DC cabling.
  • Non-Isolated Architecture: Suitable for electrical systems where galvanic isolation between the input and output is not required.

Suitable for vehicle, marine and other DC power installations requiring conversion from a higher-voltage supply to a lower-voltage electrical system.
