【产品】跳闸延迟和重启延迟可调节的单相电压监控继电器50R
50R系列是LITTELFUSE公司推出的一款单相电压监控继电器,具有电压感应电路,可在低压条件下持续监控单相电源。风扇,压缩机,空调,热泵,井泵,污水泵和小型输送机电机上的单相电机均适用于50R系列。
检测到有害状况时,MotorSaver的输出继电器在指定的跳闸延迟后停用。电源线状态恢复到可接受的水平并经过指定的时间后(重新启动延迟),输出继电器重新激活。跳闸延迟可防止由于电力线条件的快速波动引起的误跳闸。
特性优势
专有的电压检测电路——在低电压条件下持续监控单相电源
可调节的跳闸延迟(-3型号)和重启延迟(-2型号)设置——发生故障后,防止由于电源线快速波动导致的误跳闸并允许交错启动多个电机,以防止低电压状态
高压检测(-9型号)——以设定值的固定百分比进行跳闸和复位:跳闸110%,复位107%。
某些型号提供600V额定继电器触点——无需控制变压器即可将电压降至120 - 240V,用于控制电路
