Protector de sobretensión y subtensión JGGQ-80
Ⅰ. Introduction
After ten years of technological advancements, testing, and improvements, the self-resettable overvoltage and undervoltage protector is on the market. It uses a high-speed, low-power microprocessor as the core of the control circuit and a magnetic latching relay as the main circuit. Its modularized, standardized design has technical advantages such as low power consumption, precise control, an attractive appearance, anti-harmonic and anti-interference capabilities, and the ability to withstand voltages up to AC450V.
When the power supply line has overvoltage and undervoltage, the protector can quickly and safely cut off the circuit under the continuous high-voltage impact to avoid the occurrence of accidents caused by abnormal voltage sent to the terminal electrical appliances, and when the voltage returns to normal values, the protector will automatically turn on the circuit within the specified time to ensure the normal operation of the terminal electrical appliances in the case of unattended.
Economical self-resettable undervoltage protector is a product combining digital circuit and analog, which has the advantages of precise control of digital circuit, mainly manifested as the same reset time, that is, if a batch of products is energized at the same time, the action time of the batch of products is the same, there is no error of reset time between products, and the error of each reset time will not exceed 0.5 seconds; In addition, the withstand voltage is high, and it will not be damaged for a long time in the case of AC450V.
