Introduction to JY-3/1 Voltage Relay (English)
The JY-3/1 voltage relay is a specialized monitoring device designed for DC power supply systems, featuring dual-circuit voltage detection capability. Its primary function involves supervising the control bus voltage (180-240V range) for both over-voltage and under-voltage conditions, while simultaneously monitoring the under-voltage status of auxiliary circuits (charging circuit and closing bus) within 180-360V range. The relay employs electromagnetic mechanism with transparent housing for operational visibility, allowing visual inspection of internal components and setting parameters. Equipped with adjustable potentiometers for voltage threshold customization and status indicator lights, it provides reliable performance in power system protection applications. The contact system demonstrates stable switching capacity up to 50W under 250V DC/5A conditions. This product suits various DC power distribution scenarios requiring precise voltage monitoring and protection functions. 81115
产品结构与工作原理
该继电器采用插入式模块化结构，通过电压采样电路与可调基准电位比较来判断电压状态，经滤波处理后驱动出口继电器。电磁系统设计包含双线圈配置，用户可根据需要选择串联或并联连接方式以扩展整定范围。当被测电压超过设定阈值时，过压继电器触点闭合；当电压降至0.8倍整定值时自动返回。欠压监测功能则在电压低于设定值时触发动作，具有≤3%的动作一致性和≥0.95的返回系数。产品工作温度范围-10℃~+50℃，功率消耗≤15W，满足长期运行要求。1616
Technical Specifications
This device operates with 200V DC auxiliary power (terminal ③+ and ⑨-), featuring ≤1.5s response time at 1.1 times setting value for over-voltage detection, and equivalent response speed when voltage drops to 0.5 times setting value for under-voltage scenarios. The consistency of operating values remains within 3% deviation, with temperature-induced variation below ±5% of set value. Its mechanical construction includes front-panel accessible adjustment components and rear-terminal wiring configuration, supporting DIN rail or panel mounting options. The relay demonstrates vibration resistance and maintains stable performance under continuous 1.1 times rated voltage operation at 40℃ ambient temperature. 2514
