Ebusbar relays are widely deployed across the following key domains

● New Energy Vehicle High-Voltage Power Distribution Unit (PDU, BDU, Multi-in-One)

● Charging Infrastructure:

Compatible with 120kW–720kW heavy-duty truck ultra-fast charging and passenger vehicle 800V high-voltage platforms, meeting high-frequency breaking requirements.

● Energy Storage Systems:

Provides 1000V/1500V DC-side switching control for utility-scale, commercial & industrial (C&I), and residential energy storage, ensuring safe and reliable long-term grid-connected operation.

● Vehicle Applications:

Perfectly suited for mainstream 800V/1000V high-voltage vehicle platforms, including passenger cars, commercial vehicles, and new energy heavy-duty trucks. Serves as a core high-voltage switching component for main battery circuits, fast charging circuits, air conditioning, and electric control systems. The fully sealed ceramic insulation structure effectively withstands harsh automotive operating conditions such as vibration, temperature cycling, humidity, and condensation, eliminating risks of high-voltage creepage, breakdown, and leakage.

● AI Data Centers:

Compatible with next-generation 800V/1500V high-voltage DC power architectures, supporting AI compute racks and high-density, high-power power supply systems. Leveraging ceramic sealing and rapid hydrogen-based arc extinction, it handles millisecond-level load fluctuations, frequent start-stop cycles, and short-circuit interruptions, eliminating arc hazards and power supply disruptions. Ensures 24/7 uninterruptible stable power supply for data centers, adapting to the precise temperature and humidity control requirements of high-reliability server room environments.
