إعادة التعيين التلقائي لواقيات الجهد الزائد والمنخفض JGGQ-80

After 10 years of technical precipitation, N times of testing and technical improvement, JGGQ-80 self-resettable Automatically reset over and under voltage protectors is on the market, using high-speed micro-low-power processor as the core of the control circuit, magnetic latching relay as the main circuit, and modularized standard design, which has the technical advantages of low power consumption, precise control, beautiful appearance, anti-harmonic, anti-interference, and withstand voltage up to AC450V.

Ⅰ. Introduction

10 years of technical precipitation, N times of testing and technical improvement, JGGQ-80 model Automatically reset over and under voltage protectors Listed on the market, the control circuit adopts high-speed micro-low-power processor as the core, the magnetic latching relay as the main circuit, and the analogized standard design, which has the technical advantages of low power consumption, precise control, beautiful appearance, anti-harmonic, anti-interference, withstand voltage up to AC450V, withstand current up to 3000A, etc.

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.
