TXXH electronic load limiting automatic controller

1、 Scope of application: Intelligent electronic load limiting automatic controller, also known as power limiting automatic controller, current limiting automatic controller, fully automatic current limiting controller. Suitable for AC 50Hz, working voltage 220V, current 0.5-20A, power 110W-4.4kW. It can be used for automatic power control in hotels, student dormitories, factory dormitories, civil buildings on construction sites, and designated power consumption areas. The main purpose is to restrict the illegal use of resistive load power electric heating equipment, such as electric furnaces and fast heating devices, without affecting the use of computers, electric fans, ordinary instruments, televisions, incandescent lamps, electronic fluorescent lamps, etc. (the total power should not exceed the nominal power). Thus, it plays a role in limiting the cost of electricity, especially in limiting the occurrence of fires caused by overcurrent heating in power lines, which helps to eliminate safety hazards. 2、 Model and specifications of automatic power limiting controller

★Load limiting automatic controllerIf the actual load current exceeds the rated current and the time is within 10-50 seconds, the power limiting controller will automatically disconnect the load power supply, and the overload protection indicator red light will automatically light up.
★ Overload handling: First, handle the overloaded load power supply (unplug the illegally used electrical appliances). When the rated current of the power limiting automatic controller is reached, the controller will automatically detect that the load power is lower than the nominal load power. Within 10-50 seconds, the green time indicator light will automatically light up, which can restore normal operation and power supply. Otherwise, the controller will automatically trip continuously and cannot be used normally.
Due to the lack of short-circuit and leakage protection functions in the controller, the input terminal must be connected to a product with short-circuit and leakage protection functions
Due to the automatic recovery function of the controller, when the controller acts to protect and activate, the load (electrical appliance) should be immediately removed and the circuit checked. Otherwise, the controller will automatically trip continuously, and eventually burn out the controller or electrical wiring due to long-term and frequent overload connection and disconnection, causing it to be unable to function normally.

Energy saving: For example, if a dormitory illegally uses 700-1000W electric heating equipment for 2-3 hours a day, at a rate of 0.5 yuan/kWh, it can save 500 yuan in electricity bills per year
◆ Safety: It eliminates the risk of fire caused by overcurrent heating due to the use of high-power illegal electrical appliances and eliminates safety hazards.
