技术问答

LITTELFUSE推出的201A-AU系列是可自动设定范围的双量程三相电压监控继电器，能够保护电压为190～480VAC、频率为50/60Hz的电机（无论大小）。该产品的额定电压设定值可以由用户选择，自动选择的范围是200V～400V。额外的调节旋钮允许用户设置1-30秒跳闸延迟，手动重启或1~500秒重启延迟和2~8％电压不平衡跳闸点。201A-AU型号包含高级的单LED诊断，其中颜色和亮度模式可区分故障和正常情况。

图1 201A-AU系列电压监控器产品图

基于微控制器的特殊的电压和相位检测电路，可以对三相电压进行持续监控，以检测出有害的电源线状况。当检测到有害状况时，201A-AU输出继电器在设定的跳闸延迟后停用。当电源线状态恢复到指定可接受水平或重新启动延迟时间（或手动复位）后，输出继电器重新激活。

201A-AU系列电压监控器特点及优势：

专有的微控制器电路：可持续监控任何相位的损耗，低电压，高电压，电压不平衡，反相电压，快速循环，有害的电力线条件

紧凑的8引脚设计；DIN导轨或表面安装：面板安装具有灵活性

自动检测的电压范围宽：可自动检测190-480VAC之间的系统电压节省了设置时间

高级LED诊断：能够快速指示出继电器跳闸的原因

可调电压不平衡跳闸设置：允许与各种电机兼容并减少有害跳闸

可调跳闸和重启延迟设置：防止因电力线条件快速波动而造成的误跳闸。
