We provide "Generation-Grid-Load-Storage" solutions, covering the entire energy chain: generation with solar/wind converters, grid with simulators and management platforms, load with V2G chargers and battery testers, and storage with matrix systems and converters — enabling efficient new power systems.
The SDCBUS Series is a high-precision AC/DC power processing system featuring bidirectional power flow for both unidirectional and bidirectional load testing.By eliminating resistive load power consumption, the system significantly reduces energy loss.It’s widely applicable for electrical performance test of lithium-ion,lead-acid , and specialty liquid batteries.
The JHL series bidirectional programmable AC power supply is an advanced power electronic device that integrates bidirectional energy flow, high-precision output and intelligent control. It functions not only as a traditional AC power source to deliver stable voltage current output ,but also can operate as an “active load”to efficiently feed energy back to grid or energy storage recycling. It widely used in renewable energy R&D, electric vehicle testing, industrial automation, laboratory verification and other fields.
The JHT Series Grid Simulation Power System is a high-precision, high-dynamics ,and full-featured power grid simulator designed for grid adaptability testing of converter equipment in energy storage, photovoltaic and other renewable energy applications.Leveraging advanced digital control technology ,it enables four-quadrant operation and simulates grid characteristics ranging from “ideal”to “extreme harsh”conditions.
