Features: Wide Voltages working ranges: It can work in the Voltages ranges of 6-60V, and can be suitable for batteries with different Voltages levels. It have a wide ranges of application scenario. Accurate undervoltage Protective function: When the Voltages of the Battery drop to the set undervoltage value, the module will quickly disconnect the output, effectively preventing the battery from over-discharging, avoiding the battery performances degradation. Optional overvoltage Protective: Some XHM609 module may also have overvoltage Protective function. When the input Voltages exceeds a certain upper limit, the module will cut off the output, so as to prevent connection equipment from being damaged by excessive Voltages and provide more comprehensive Protective for the whole circuit systems. Fast responses speed: advanced circuit design and control chip is adopted to respond in a very short time when abnormal Voltages is detected, so as to quickly disconnect the output, ensures that the battery and connection equipment can be Protective at the moment of abnormal Voltages. High stability: Electronic components is selected, which have good stability and reliability after strict production technology and inspection Specifications: Component:ABS Size:Approx.57x42mm/2.24x1.65inch Package Includes: 1Pc Protective Module note: 1.Please allow 1-2cm errors due to manual measurement, making sure that you not mind before order. 2.Due to the differences between different monitors, the picture may not reflect the actual of the item.
