Braking resistor overload limiter highlight the function display


Crane overload limiter commonly known as limiter, which is used in overloaded crane cranes, it is designed to go beyond the traditional load cell detection methods, and its design gradually solve the overload limiter trouble, it is used in electronic control Easy to install and debug The installed monitor can display a variety of parameters: three-phase current, average current, average voltage.

   Overload limiter also uses a protection circuit, in the event of over-current, under-voltage, unbalanced phenomenon, it will automatically cut off the power. Here are some troubleshooting reference technical data:

    1, early warning function: when the weight of ≥ 90% of the rated weight, issued a low-frequency sound and light alarm

    2. Alarm protection: When the weight of ≥ 100% of the rated weight, issued a high-frequency sound and light alarm

    3. Immediate protection: When the lifting weight ≥ 105% of the rated weight, disconnect the rising circuit immediately
