HSBT4K-150-120

This bidirectional module enables bidirectional conversion between AC and DC. It employs DSP‑based control to ensure stable bidirectional performance of both the AC/DC and DC/DC stages. The DC/DC stage utilises high‑frequency isolated bidirectional conversion technology – specifically soft‑switching resonant technology – achieving high efficiency with automatic charge/discharge switching and seamless bidirectional power flow. The module supports parallel operation with automatic current sharing, and RS485 communication for convenient integration with third‑party equipment. This bidirectional power supply is widely used in battery formation and capacity grading, emergency power supplies, 5G base station energy storage, equipment burn‑in, and many other applications, making it the preferred choice for industries requiring bidirectional power flow.
