产品简介 | Product Introduction

WLD-3.5kV150A150KA20H为高压双向DC/DC变流器，由稳利达电力电子采用全数字化设计，实现电压、电流双环反馈控制。高压端电压可设置、0~3500Vdc（额定3000Vdc，**大电流150A，**大功率150kW）；低压端电压范围为高压电压×0.1~1200Vdc（**大电流150A，**大功率150kW），两侧功率对称。转换效率额定输入下>96%（额定功率**97%），电压精度±0.5%FS，静态损耗电流仅20mA（空载），辅助电源220VAC或直流定制。产品支持高压侧过压/欠压保护（可设置自恢复点）、防反接、低压侧过流/过压/欠压/过温/短路保护及下垂并联定制，启动与电压/电流控制均可通过CAN或RS485（Modbus RTU）远程设置。整机采用风冷、IP20防护，工作温度-20~+55℃，海拔**6000米，适用于高压直流变换、直流微电网、储能、特种电源等高压大功率场景。

WLD-3.5kV150A150KA20H is a high-voltage bidirectional DC-DC converter, delivered by Wenlida Power Electronics with an all-digital design and dual-loop voltage/current feedback. The HV side is configurable, 0-3500Vdc (rated 3000Vdc, max 150A, max 150kW); the LV side ranges from HV×0.1 to 1200Vdc (max 150A, max 150kW), with symmetric power on both sides. Conversion efficiency is >96% at rated input (up to 97% at rated power), voltage accuracy ±0.5%FS, quiescent loss only 20mA (no-load), and auxiliary power 220VAC or DC customization. The product supports HV over-/under-voltage protection (configurable recovery point), reverse-polarity protection, LV over-current/over-voltage/under-voltage/over-temperature/short-circuit protection and droop-parallel customization; start-up and voltage/current control can be remotely configured via CAN or RS485 (Modbus RTU). With air cooling, IP20 protection, -20~+55℃ operating temperature and up to 6000m altitude, it suits HV DC conversion, DC micro-grids, energy storage and special high-voltage high-power applications.

本产品为双向DC/DC变流器，采用全数字化设计，电压、电流双环反馈，高压侧与低压侧之间实现双向大功率能量交换。运行注意：高压侧电压必须高于低压侧电压；实际运行需满足"高压电压×0.1 < 低压电压 < 1200"。

This product is a bidirectional DC-DC converter with an all-digital design and dual-loop voltage/current feedback, enabling bidirectional high-power energy exchange between the HV and LV sides. Note: the HV-side voltage must be higher than the LV side; in operation, "HV×0.1 < LV < 1200" must be satisfied.
