Weifa Electronics raises $15 million Series C to chase AI data center demand
What's the deal? Weifa Electronics Technology (Changzhou), a Chinese maker of safety components for power systems, has raised US$13.8M in a Series C round. New backers Guoke New Energy and Huatai Zijin led the round, with existing shareholders Jianfa Emerging Investment, Yida CapitalDealroom has a profile for this one.

What's the endgame? Founded in 2020 and based in Jiangsu province, Weifa builds products spanning "sensing, control, execution, and protection." It supplies contactors, solid-state relays, and distribution modules for high-voltage DC power, alongside eddy-current sensors and encoders for vehicles and robots.
Why now? The company is pushing its automotive and energy-storage expertise into AI data centers (AIDC), where Nvidia is driving the industry toward an 800V high-voltage DC architecture. That shift creates fresh demand for DC switches and safety devices. Weifa says its contactors and solid-state relays have already entered leading data center customers' supply chains.
The funds will go three ways: scaling AIDC solid-state products to mass production, expanding sensor and robot-encoder production lines, and accelerating overseas expansion off existing European automaker contracts.
What could go wrong? The AIDC story is still mostly promise. Weifa's solid-state circuit breakers remain in the prototype stage, developed with an academician team to Nvidia's 125A and 1250A specs, with North American launch planned by year-end. Its robot joint encoders are likewise still in testing with top customers, so mass production and client validation are the key milestones to watch.
The signal: Investors are betting on the overlap of energy and computing power. "High-voltage DC safety protection may seem like a niche market, but it actually has extremely high barriers to entry," Jianfa Emerging Investment said, pointing to the need for "long-term accumulation of technology and verification records from top customers." For a company whose core business still rests on EVs, storage, and charging, the round funds a bet that the same capabilities can carry into the data center boom.
