项目简介 | Project Introduction

本项目为2.4MW大功率直流电源DCDC系统，由稳利达电力电子提供整套多路并联直流升压变换解决方案。系统由18台200kW DCDC功率模块并联构成，额定功率2400kW；输入侧电压580-650Vdc（整机**大电流690A），输出侧电压900-930Vdc（整机**大电流2667A），转换效率98%。设备将580-650V直流输入升压至900-930V稳定直流输出，支持恒压、恒流、恒功率三种工作模式，静态稳定度±0.5%FS、动态±3%FS，输出精度高、响应快，适用于电解/化成直流电源、动力电池化成与分容、工业大功率直流供电、储能系统升压等场景。整机采用强制风冷，配置触摸屏（支持远程监视）、RS485（Modbus RTU）与以太网（Modbus TCP）双通道通讯，保护完备，故障解除后自动恢复运行。

This project is a 2.4MW high-power DC power-supply DC-DC system, delivered by Wenlida Power Electronics as a complete multi-parallel DC step-up conversion solution. The system consists of eighteen 200kW DC-DC power modules in parallel, with a rated power of 2400kW. The input side is 580-650Vdc (max 690A for the whole unit), and the output side is 900-930Vdc (max 2667A), with a conversion efficiency of 98%. The device steps up 580-650V DC input to a stable 900-930V DC output, supporting CV, CC and CP operation modes, with static stability ±0.5%FS and dynamic ±3%FS — high output accuracy and fast response. It is suitable for electrolysis/formation DC power, EV-battery formation & sorting, industrial high-power DC supply, and energy-storage step-up. The unit uses forced air cooling, a touch screen (remote monitoring supported), dual-channel RS485 (Modbus RTU) and Ethernet (Modbus TCP) communication, comprehensive protections and auto-recovery after fault clearance.

整套系统配置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。输入侧分1-6路接入（580-650Vdc），经18台并联DCDC模块升压后汇集至900-930Vdc输出母线，向直流负载统一供电。所有电缆和信号线均采用底部下进线、下出线方式，整机由2台并柜组成。

The system is equipped with a 10-inch local touch screen for on-site data monitoring and touch operation, and one RS485 port for remote telecontrol, telemetry and tele-adjustment. Input enters through channels 1-6 (580-650Vdc), steps up via eighteen paralleled DC-DC modules, and is collected on the 900-930Vdc output bus to supply DC loads uniformly. All power and signal cables enter and exit from the bottom; the whole system consists of two paralleled cabinets.

设备搬运说明 | Equipment Handling Instruction

机柜底座开有两个方形孔，搬运时叉车两根货叉通过方形孔叉入机柜底部，移动过程中需保证缓慢、平稳，避免设备磕碰倾倒。

Two square holes are reserved at the cabinet base. Insert two forklift forks through the square holes to the cabinet bottom during handling. Move slowly and steadily to prevent collision or tipping-over.
