Bi-directional Power Module
TC4850C
In power grid substations, assessing the status of DC battery banks primarily relies on high-cost, periodic manual discharge testing. The TC4850C, integrated with its supporting remote capacity verification system, enables scheduled or real-time remote-controlled capacity testing. Furthermore, the discharge load is self-consumed by the system, making the process both energy-efficient and environmentally friendly.
Product Features
High Efficiency & Energy SavingAdopts advanced soft-switching technology, delivering high power density.
01
Safety & ReliabilityThe module features DC anti-reverse connection protection at both input and output, preventing reverse connection of positive and negative terminals and supporting live hot-plugging.
02
