一、客户背景​

天津某大型汽车零部件制造企业在新能源汽车核心部件（电机壳体、电池托盘）生产线升级项目中，需为焊接机器人配套传感器、伺服控制器、精密检测仪器及 PLC 控制系统提供安全稳定的低压供电。由于车间存在多区域电压差异（部分老旧设备 230V 供电，新设备适配 400V），且焊接工序产生电磁干扰、金属粉尘较多，对设备绝缘防护、抗干扰能力及安装便捷性提出严苛要求，亟需一款适配复杂工况的安全供电方案。​

Customer Background​

A large automotive parts manufacturer in Tianjin required a safe and stable low-voltage power supply for welding robot supporting sensors, servo controllers, precision testing instruments, and PLC control systems in its new energy vehicle core components (motor housing, battery tray) production line upgrade project. Due to voltage differences across multiple workshop areas (230V for some old equipment and 400V for new equipment), coupled with electromagnetic interference and heavy metal dust generated by welding processes, strict requirements were imposed on equipment insulation protection, anti-interference capability, and installation convenience. A safe power supply solution suitable for complex working conditions was urgently needed.​

二、产品选型​

客户选用 Legrand 罗格朗单相安全变压器 044215，额定视在功率 250VA，其 6 档宽范围初级电压（215V/230V/245V/385V/400V/415V）可灵活匹配车间不同区域供电规格，次级稳定输出 24V 安全电压，精准适配低压控制设备需求。产品采用 IEC 85 标准 B 级绝缘材料（耐温 130℃）、IP2X 防尘防护及 IK04 抗冲击设计，有效抵御金属粉尘侵入与车间机械碰撞；模块化紧凑结构（106×123×115mm）+ 螺钉端子连接，满足控制柜高密度集成需求，且接线操作便捷，完全契合汽车零部件行业连续生产、高可靠性的核心诉求。​

Product Selection​

The customer selected the Legrand single-phase safety transformer 044215 with a rated apparent power of 250VA. Its 6-range wide primary voltage (215V/230V/245V/385V/400V/415V) can flexibly match the power supply specifications of different workshop areas, while the stable 24V safety voltage output on the secondary side accurately meets the needs of low-voltage control equipment. Adopting Class B insulation material (temperature resistance 130℃) compliant with IEC 85, IP2X dustproof protection, and IK04 impact resistance design, the product effectively resists metal dust intrusion and mechanical collisions in the workshop. The modular compact structure (106×123×115mm) combined with screwed terminal connection meets the high-density integration requirements of control cabinets and enables convenient wiring operations, fully aligning with the core demands of continuous production and high reliability in the automotive parts industry.​

三、应用效果​

该变压器成功集成于生产线 12 台控制柜内，通过多电压档位快速适配新旧设备供电需求，无需额外配置电压转换装置，大幅缩短了生产线升级周期。B 级绝缘材料与优化的电磁兼容性设计，有效隔绝了焊接工序产生的电磁干扰，确保精密检测仪器的测量精度（误差降低至 ±0.02mm）；IP2X 防护等级杜绝了金属粉尘进入设备内部，螺钉端子的防松动设计保障了连续生产中的接线稳定性。设备运行至今零故障，24V 安全电压为操作人员提供了可靠防护，生产线停机时间较升级前减少 40%，核心部件加工合格率提升 3%，显著增强了企业的生产效率与产品竞争力。​

Application Performance​

The transformer was successfully integrated into 12 control cabinets of the production line. Its multi-voltage range design quickly adapted to the power supply needs of new and old equipment without the need for additional voltage conversion devices, greatly shortening the production line upgrade cycle. The Class B insulation material and optimized electromagnetic compatibility design effectively isolated electromagnetic interference generated by welding processes, ensuring the measurement accuracy of precision testing instruments (error reduced to ±0.02mm). The IP2X protection class prevented metal dust from entering the equipment, and the anti-loosening design of screwed terminals guaranteed wiring stability during continuous production. The equipment has achieved zero failures since operation, and the 24V safety voltage provided reliable protection for operators. Compared with before the upgrade, the production line downtime was reduced by 40%, and the qualified rate of core component processing increased by 3%, significantly enhancing the enterprise’s production efficiency and product competitiveness.​

四、典型优势​
