The BRUSA BSC724-12V-C04 Liquid-Cooled DC-DC Converter is a premium, automotive-grade power conversion unit engineered for electric vehicles (EVs) and high-voltage hybrid architectures. Manufactured in Switzerland by BRUSA Elektronik AG (a renowned Tier-1 supplier of advanced EV drivetrain components), this unit safely steps down power from a 400V-class main traction battery to provide a massive 3kW of clean, stable 12V power for the vehicle's low-voltage auxiliary systems (lights, infotainment, wipers, pumps, and ECUs).

Key Features:
Massive 3kW Output – Capable of delivering up to 250 Amps at 12V, completely eliminating the need for a traditional mechanical alternator. It provides more than enough power to run heavy auxiliary loads like electric power steering pumps, cabin heaters, and high-fidelity audio systems.
Active Liquid Cooling – Features two robust aluminum barbed ports designed to plumb directly into the vehicle's thermal management loop. This ensures the internal power electronics remain at optimal temperatures during extreme continuous power draw.
Automotive-Grade Connectors – Equipped with a heavily shielded orange TE Connectivity receptacle for the high-voltage DC input, and a high-current multi-blade Amphenol connector for the massive 12V DC output and CAN-bus signal communication.
Machined Thermal Base – The bottom of the heavy-duty cast aluminum housing features a precision-machined thermal contact plate, allowing for additional conductive heat sinking if bolted to a cold plate or chassis rail.
High-Frequency Galvanic Isolation – Provides absolute electrical separation between the dangerous 400V high-voltage battery system and the safe 12V vehicle chassis, protecting both the driver and the sensitive 12V electronics.
Ideal For:
Complete factory Electric Vehicle (EV) and Plug-in Hybrid (PHEV) manufacturing
High-end EV conversions (Classic cars, Hot Rods, Porsche/VW conversions) utilizing 400V battery architectures (like Tesla or Nissan Leaf modules)
Electric marine propulsion systems requiring massive 12V house power
Commercial electric transit buses and delivery vehicles
