TC Charger 3.3kW On-Board Charger

The TC Charger 3.3kW On-Board Charger (Model HK-MF-108-32) is a highly efficient, ruggedized AC-to-DC power converter designed specifically for charging the high-voltage battery packs of electric vehicles (EVs) and industrial equipment. Manufactured by Tiecheng Information Technology Co., Ltd. (a globally recognized leader in EV charging solutions), this "HK-M" series charger features active air cooling and smart CAN-bus integration, making it a favorite for both OEM applications and custom EV conversions.

Key Specifications:

• Category: Automotive Parts & Accessories / EV High Voltage Components / On-Board Chargers (OBC)

• Product Type: 3.3kW Air-Cooled On-Board Charger

• Manufacturer: Tiecheng Information Technology Co., Ltd. (TC Charger)

• Model / Part Number: HK-MF-108-32

• AC Input Range: 90 - 265V AC (50/60Hz) @ 16A Max

• DC Output Range: 100 - 200V DC

• Maximum Output Current: 32A DC

• Control / Communication: CAN Bus (Configuration: CAN1430)

• Cooling Method: Active Air Cooling (Top-mounted fan + finned heatsink)

Key Features:

• Active Air Cooling – Features a massive die-cast aluminum finned heat sink topped with a high-RPM cooling fan and wire finger guard. This design ensures maximum thermal dissipation during heavy charging cycles without the need for complex liquid-cooling plumbing.

• Smart CAN-Bus Integration – The central black multi-pin connector interfaces directly with the vehicle's Battery Management System (BMS) via CAN-bus, allowing the charger to dynamically adjust output voltage and current based on real-time battery health and temperature.

• Automotive-Grade HV Connectors – Equipped with highly secure, touch-safe orange connectors. The 3-pin connector handles the incoming AC mains power, while the 2-pin connector delivers the high-voltage DC output to the battery pack.

• Rugged & Weatherproof Enclosure – The internal circuitry is heavily potted to withstand intense road vibrations. A built-in Gore-Tex style breather valve prevents internal condensation from temperature swings, ensuring reliable operation in harsh weather.

• Integrated Grounding – Features a dedicated external grounding lug on the lower chassis to ensure absolute electrical safety during grid-tied charging.

Ideal For:

• Custom Electric Vehicle (EV) and Hot Rod conversions

• Golf carts, neighborhood electric vehicles (NEVs), and electric ATVs

• Marine electric propulsion battery banks

• Heavy-duty electric forklifts and industrial material handling equipment

• Upgrading slower factory chargers for faster overnight charging
