ZHXK30 smart limiter automatic controller description
I. Overview
ZHXK30 intelligent power limited automatic controller, (electronic limit automatic controller) is suitable for AC 50Hz, working voltage 24V-220V, current 0.5-20A, power 110W-4400W, can be used in hotel, school factory dormitory and civil construction site. The use of power at the specified power location is automatically controlled. Mainly to restrict the illegal use of resistive load power electric heating equipment, (such as electric stoves, heat faster) and other illegal appliances put into use, this product is to save electricity, safe electricity, especially to limit the aging of the line and eliminate the use of high-power illegal appliances. Fire caused by overheating of overcurrent is a function to help eliminate potential safety hazards.
Second, technical parameters:
1, the working voltage: AC220V, 50HZ
2. Rated current and/or power: 0.5A/110W, 1A/220W, 2A/440W, 2.3A/500W, 3A/660W, 5A/1100W, 6A/1320W, 10A/2200W, 15A/3300W, 20A/4400W, 25A/5500W, 30A/6600W.
3, (1.2 times) action time 5S, automatic reset time 20S ± 5S
Third, according to the user needs other specifications of the "power limited automatic controller" production.
Four: overload handling methods and precautions
1: When the load current exceeds the rated current value, the controller will automatically disconnect the load power within 5 seconds. The overload protection indicator will automatically light up.
2, overload processing: should immediately unplug the overload load power (infrared use of electrical appliances), reach the rated current of the controller, in <30 seconds time the green light automatically lights up automatically resume normal operation power supply, otherwise control Automatic continuous tripping cannot be used normally.
3, matters needing attention
A: After the controller has no short circuit and leakage protection function, the input must be connected to the product with short circuit and leakage protection function.
B: Since the controller has an automatic recovery function, when the controller protects and operates, immediately remove the load (using electrical appliances) and check the circuit, otherwise the controller will automatically trip continuously, and will eventually be connected due to frequent overloading for a long time. Disconnect it and burn out the controller or the power line and cause it to not be used normally.
V: Energy Saving and Security
Energy-saving: For example, a 700-1000W electric heating equipment that is illegally used for 2-3 hours a day in a dormitory can save 500 yuan in electricity costs in a year at 0.5 yuan/kWh.
Safety: Eliminating the effect of overheating caused by over-current heating caused by the use of high-power illegal electrical appliances to eliminate fire safety hazards.
Sixth: wiring and installation dimensions, the input terminal is connected to the power main switch and leakage switch, 35mm standard rail installation.
Gear Sensor has been widely used in the automotive and industrial field, which is important to the measurement of velocity, angel, angular velocity, direction of rotation.
