This project is a 1.2MW supercapacitor DC-DC cabinet, delivered by Wenlida Power Electronics as a complete bidirectional supercap DC-DC conversion and collection solution. The system consists of seven 171.5kW bidirectional DC-DC modules (bus side 100-520Vdc, supercap side 600-900Vdc; ≤350A bus-side and ≤286A supercap-side current per module, 98% efficiency) in parallel, plus one 20kW AC-DC (AC260-530Vac 3-phase input, DC50-1000Vdc output, max 40kW) for auxiliary supply. The whole unit is rated 1.2MW: bus port 1200kW/2400A, supercap port 1200kW/2000A, AC380V port 40kW. It supports CV/CC/CP modes, static stability ±0.5%FS and dynamic ±3%FS, sustained working time ≥50s, and parallel or standalone operation. It features a touch screen (with remote monitoring), dual-channel RS485 (Modbus RTU) and Ethernet (Modbus TCP) communication, air cooling and IP21 protection. It suits supercap energy storage, high-power short-duration discharge, voltage-sag mitigation, port potential-energy recovery and rail transit regenerative braking.

整套系统提供10寸本地触摸屏，供客户监控数据和触摸操作；提供一路RS485接口支持遥控、遥测、遥调功能；可以多台并联，也可以单台运行。7台DCDC模块在母线侧（100-520Vdc）与超容侧（600-900Vdc）之间双向变换，将超级电容能量稳定汇入直流母线，并由ACDC提供系统辅助电源。所有电缆和信号线均采用底部下进线、下出线。
The system provides a 10-inch local touch screen for on-site monitoring and touch operation, one RS485 port for remote telecontrol, telemetry and tele-adjustment, and supports parallel or standalone operation. Seven DC-DC modules perform bidirectional conversion between the bus side (100-520Vdc) and the supercap side (600-900Vdc), collecting supercapacitor energy onto the DC bus, with an AC-DC module supplying auxiliary power. All power and signal cables enter and exit from the bottom.
