Self-Recovering Over/under Voltage Protector Jggq-80

I. Introduction

 Built on 10 years of technical expertise and countless rounds of testing and technical improvements, the JGGQ-80 self-recovery over-voltage and under-Voltage Protector has been launched. Its control circuit adopts a high-speed, low-power microprocessor as the core and a magnetic latching relay as the main circuit, featuring a modular standard design. It offers technical advantages such as low power consumption, precise control, an elegant appearance, harmonic resistance, anti-interference capability, a withstand voltage up to AC450V, and a withstand current up to 3000A.

  When the power supply line experiences overvoltage or undervoltage, the protector can quickly and safely cut off the circuit under sustained high-voltage surges, preventing abnormal voltage from being delivered to terminal electrical equipment and causing accidents. When the voltage returns to normal, the protector will automatically reconnect the circuit within a specified time, ensuring that terminal electrical equipment operates normally under unattended conditions.

  The economy-type self-recovery overvoltage and underVoltage Protector is a product that combines digital and analog circuits, offering the advantage of precise digital circuit control. This is mainly reflected in the fact that the reset time is completely consistent—that is, if a batch of products is energized at the same time, the operating time of that batch will be identical, with no variation in reset time between products, and the reset time error for each operation will not exceed 0.5 seconds. Since the sampling circuit uses imported electronic components, the error in the overvoltage and undervoltage values does not exceed 3V. In addition, it has a high voltage withstand capability and will not be damaged even after prolonged operation at AC450V.
