The Sevcon (now part of BorgWarner) 622/11100 F is a robust DC-DC converter that efficiently steps down a high voltage DC input (from a 36V or 48V battery system) to a stable 12V output. With a continuous power rating of 300 watts, it is designed to power 12V accessories, control systems, lighting, and instrumentation in electric and hybrid vehicles, industrial machinery, and other mobile equipment.
The “FT01” in the part number is a common Sevcon designation for this family of converters.
Key Features
-
High Efficiency:Â Minimizes energy loss and heat generation, which is critical for battery-powered vehicles.
-
Wide Input Voltage Range:Â Can handle the typical voltage fluctuations of 36V and 48V battery systems, including during charging and discharging.
-
Stable 12V Output:Â Provides a clean and regulated 12V supply, essential for sensitive electronic equipment.
-
High Power Output:Â 300W (25A) capacity to run multiple accessories simultaneously.
-
Robust Construction:Â Built to withstand the vibrations, shocks, and environmental conditions found in mobile and industrial applications.
-
Thermal Protection:Â Includes built-in safeguards to prevent damage from overheating.
-
Water and Dust Resistance (IP Rating): Many models in this series are sealed to a high IP rating (e.g., IP67), making them suitable for harsh environments. (Note: Confirm the specific IP rating for this exact model number from the datasheet).
-
Isolated Output:Â The output is typically electrically isolated from the input, enhancing safety and reducing noise.

Important Notes and How to Use
-
Confirm Input Voltage: It is crucial to verify whether your specific unit (622/11100 F) is configured for a 36V or a 48V nominal input. Applying the wrong input voltage can destroy the unit.
-
Datasheet is Essential: The above specifications are general for this model series. Always obtain the official Sevcon/BorgWarner datasheet for the 622/11100 F for absolute certainty on wiring, input range, derating curves, and exact dimensions before installation.
-
Adequate Cooling:Â Ensure the converter is mounted on a flat surface to allow for proper heat dissipation. Do not operate it at or near its full 300W rating in a confined space without adequate airflow.
-
Wiring:Â Use appropriately sized wires for the high current (25A+ on the 12V output side) to prevent voltage drop and overheating. Always fuse both the input and output lines according to the manufacturer’s recommendations.
