The lighting voltage stabilizer avoids the situation where the grid voltage rises in the second half of the night, which may cause the lamps to be easily damaged when operating in an environment with a voltage higher than the rated voltage for a long time, through the method of voltage reduction. It adopts the control mode of soft start and soft shutdown to prevent the impact of over - voltage and cold - start current on the lamps, greatly reducing the damage rate of the lamps. For lamps such as sodium lamps and mercury lamps, an adjustable full - voltage preheating automatic time is set, so that the lamps can be more fully preheated and smoothly transition to the normal working state.
LE-100NPI LE-80NPI Street Lighting Electromagnetic Voltage Stabilizing and Regulating Device and Voltage - Regulating Energy - Saving Device is a new generation of wireless remote intelligent lighting controller independently developed, designed, and produced by Zhejiang Juchuan Electrical Technology Co., Ltd. This product is based onGPRS/3G/4G wireless communication technology and cloud platform technology. Wherever there is network signal coverage, users can remotely control and monitor the controller at any time using the mobile client software or the computer client software. It comes with three time schemes: date - time scheme, weekly scheme, and longitude - latitude scheme. Users can choose any one of these time schemes for timing control, and it also supports the external connection of a illuminance sensor for automatic illuminance control.

Advantages of LE-100NPI LE-80NPI Street Lighting Electromagnetic Voltage Stabilization and Regulation Device Voltage Regulating and Energy Saving Appliance:
1. Overcurrent protection circuit. An automatic fallback protection circuit is adopted. If the overcurrent protection circuit starts to work and the output voltage drops, the output current will be more concentrated. Therefore, compared with the drooping protection circuit, the heat loss of the chip in an abnormal state such as a short circuit can be controlled to 1/3～1/5 of the original.
2. Temperature protection circuit. The temperature protection circuit automatically stops output when the chip temperature exceeds Tj = 150°C, preventing damage to the chip caused by excessive temperature, thus achieving the purpose of protecting the chip. If the chip temperature drops, there is a hysteresis width to resume output.
3. Overvoltage protection circuit. The overvoltage protection circuit is only built into the product. If a surge of over 25V occurs in the output, the protection circuit will be activated to improve the voltage withstand performance of the internal components of the chip. Even if the input voltage exceeds 50V, it can prevent damage to the chip.
