Ⅰ.导言

Over And Under Voltage Protectors
Over And Under Voltage Protectors

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.

当供电线路出现过电压和欠电压时，保护器能在持续高压冲击下快速安全地切断电路，避免因异常电压送至终端电器而导致事故的发生，当电压恢复到正常值时，保护器会在规定时间内自动接通电路，确保终端电器在无人值守的情况下正常运行。

经济型自复位欠压保护器是数字电路与模拟量相结合的产品，具有数字电路控制精确的优点，主要表现为复位时间相同，即一批产品同时通电，该批产品的动作时间相同，产品之间没有复位时间的误差，每次复位时间的误差不会超过 0.5 秒；另外，耐压高，在 AC450V 的情况下，长时间也不会损坏。
