一、客户背景​

惠州某智能装备制造企业在新建自动化生产线项目中，需为分布式传感器、小型执行器及控制模块提供安全稳定的低压供电。由于生产现场供电环境复杂，存在多电压规格需求，且对设备安全防护、安装空间及运行可靠性有严格要求，需一款适配性强、安全等级高的供电解决方案。​

Customer Background​

An intelligent equipment manufacturer in Huizhou required a safe and stable low-voltage power supply for distributed sensors, small actuators, and control modules in its new automated production line project. Due to the complex power supply environment on-site, multiple voltage specifications were needed, along with strict requirements for equipment safety protection, installation space, and operational reliability. A highly adaptable and high-safety power supply solution was essential.​

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，具备 6 档多范围初级电压（215V/230V/245V/385V/400V/415V）适配能力，次级稳定输出 24V 安全电压。产品采用 IEC 85 标准 B 级绝缘材料、IP2X 防护等级及 IK04 抗冲击设计，搭配模块化结构与螺钉端子连接，完全满足复杂工业环境下的安全供电与灵活安装需求。​

Product Selection​

The customer selected the Legrand single-phase safety transformer 044215 with a rated apparent power of 250VA. It features 6-range multi-voltage adaptability for primary side (215V/230V/245V/385V/400V/415V) and stable 24V safety voltage output on the secondary side. Adopting Class B insulation material (compliant with IEC 85), IP2X protection class, and IK04 impact resistance design, combined with a modular structure and screwed terminal connection, the product fully meets the safety power supply and flexible installation requirements in complex industrial environments.​

三、应用效果​

该变压器成功集成于生产线控制柜内，通过多电压档位灵活匹配现场供电环境，无需额外配置电压转换器，大幅简化了系统布线。B 级绝缘与 IP2X 防护设计有效隔绝了现场粉尘、异物干扰及触电风险，螺钉端子与清晰标记确保了接线精准高效。设备运行期间稳定可靠，24V 安全电压为低压用电部件提供了持续保障，显著降低了因供电不稳定导致的设备停机概率，提升了生产线整体运行效率。​

Application Performance​

The transformer was successfully integrated into the production line control cabinet. Its multi-voltage range design flexibly matched the on-site power supply environment, eliminating the need for additional voltage converters and greatly simplifying system wiring. The Class B insulation and IP2X protection effectively isolated on-site dust, foreign object interference, and electric shock risks, while the screwed terminals and clear markings ensured accurate and efficient wiring. During operation, the equipment performed stably and reliably, with the 24V safety voltage providing continuous protection for low-voltage components. This significantly reduced the probability of equipment shutdown caused by unstable power supply and improved the overall operational efficiency of the production line.​

四、典型优势​

– 250VA 额定视在功率，精准匹配中小型低压设备负载需求​

– 6 档多初级电压适配（215-415V），兼容复杂供电环境​

– B 级绝缘 + IK04 抗冲击 + IP2X 防护，筑牢全场景安全防线​

– 模块化紧凑设计（106×123×115mm），节省柜内安装空间​

– 螺钉端子 + 清晰标记，接线便捷且降低误操作风险​

Key Advantages​

– 250VA rated apparent power, accurately matching the load requirements of small and medium-sized low-voltage equipment​

– 6-range multi-primary voltage adaptability (215-415V), compatible with complex power supply environments​

– Class B insulation + IK04 impact resistance + IP2X protection, building a comprehensive safety barrier​

– Modular compact design (106×123×115mm), saving cabinet installation space​

– Screwed terminals + clear markings, enabling convenient wiring and reducing misoperation risks​

五、总结​

Legrand 罗格朗 044215 单相安全变压器在惠州某智能装备制造企业自动化生产线中的成功应用，凭借其多电压适配性、高安全防护等级及紧凑设计，完美解决了复杂工业环境下的低压安全供电难题，有效提升了系统运行的稳定性与安全性，为生产线的连续高效运行提供了坚实保障。​

Conclusion​

The successful application of the Legrand 044215 single-phase safety transformer in the automated production line of an intelligent equipment manufacturer in Huizhou has perfectly solved the low-voltage safe power supply challenge in complex industrial environments. With its multi-voltage adaptability, high safety protection level, and compact design, it has effectively improved the stability and safety of system operation, providing a solid guarantee for the continuous and efficient operation of the production line.
