The intelligent street light power-saving monitoring system, voltage-stabilizing and energy-saving lighting controllers PGL-1250SD and PGL-350SD directly perform "AC-AC" transformation on the mains power. The working process of the system is based on the lighting needs at the equipment working site. The control strategy is a hybrid control strategy of "light control + time control". The intelligent control software embedded in the control circuit adjusts the duty cycle of the PWM control signal, and then adjusts the voltage amplitude of the equipment output, so as to achieve the lighting intensity according to the on-site needs. Since the thyristor network of the voltage-stabilizing control device is located on the output side of the compensation transformer and is stepped down by the autotransformer, it not only reduces the on-off voltage of the thyristor (from 220V to 200V or lower), but also suppresses the inrush current generated during gear shifting (the autotransformer itself is a high-power reactor), thus greatly improving the working reliability and anti-interference ability of the thyristor.
Product specifications: 10KW, 15KW, 20KW, 30KW, 40KW, 45KW, 50KW, 60KW, 80KW, 100KW, 120KW, 150KW, 160KW, 180KW, 200KW, 250KW, 300KW, 350KW, 400KW;
Applicable scope: Most users can install it, such as schools, shopping malls, office buildings, parks, residential areas, etc. However, the power-saving device is not applicable in the case of long-term low voltage and equipment that requires voltage control. Power-saving effect guarantee: After installation, the power-saving effect is ensured. The investment can be recovered in about one to two years from the saved electricity cost after installation. Quality guarantee: The product is manufactured with high-quality materials under strict control. Under normal use, the manufacturer provides a 2-year free warranty, and the service life is up to 20 years.
Product functional features of the voltage-stabilizing and energy-saving lighting controller:
The other is that the AC contactor is used as a bypass switch circuit, which is connected in parallel with the main circuit.
Optional G/GPRS global real-time (mobile phone) monitoring. Monitor the operation and faults of the equipment through display, sound, etc., and take protective measures in time.
It needs to have good duty cycle performance. The so-called duty cycle performance means that even under the condition of very low voltage, the output voltage can still be maintained. At the same time, the switching speed and conduction time of the power voltage-regulating and stabilizing device also determine its usage cost.
The 30KVA voltage regulation of the lighting energy-saving voltage-regulating and stabilizing device can quickly and automatically compensate for the over-voltage and under-voltage of the power grid, and provide a sinusoidal voltage for the load.
Strong resistance: All components in the control unit adopt photoelectric isolation, and different anti-noise levels are set to avoid malfunctions of the soft starter caused by the main power grid.
The voltage regulation of the intelligent street lamp energy saver can quickly and automatically compensate for over-voltage and under-voltage of the power grid, providing a pure sine wave voltage for the load.

Intelligent street lamp energy-saving monitoring system, voltage-stabilizing energy-saving lighting controller PGL-1250SD, PGL-350SD. Energy saving: It uses a brightness sensor to automatically adjust the brightness of the lamp to achieve energy-saving effects. Using sensors, when a person enters the sensor area, the light gradually brightens. When a person leaves the sensor area, the light gradually dims or turns off, controlling the "always-on lights" in some corridors to achieve the purpose of energy saving. For example, in order to save electricity, a certain place replaced all corridor lights with 5W energy-saving lamps, which reduced energy consumption. However, the light comfort of energy-saving lamps is poor, the illuminance decreases, and there is a problem of a downgrade in the restaurant level. Sensor control is recommended.
Operation and user manual of the voltage-stabilizing energy-saving lighting controller
During operation, it displays relevant electrical parameters such as three-phase output voltage, current, and power.
It has a Chinese/English LCD operation interface, menu-style parameter setting, and a comprehensive help and fault prompt function.
It is equipped with an RS-485 communication interface, which can realize communication with the host computer. Parameters can be set and modified through the host computer, and lighting can be remotely monitored. The communication protocol is the Modbus protocol, and the communication rate is 4800bps or 9600bps.
Parameter setting instructions: Press Enter to enter the "Parameter Setting", and then press Enter again to enter the verification: 000001, and enter the parameter setting interface. If you need to set the time: Move the cursor to the "Set Time", press Enter, the cursor will flash. At this time, you can use the up, down, left, and right keys to set the time. After setting, press Enter to confirm, and press Esc to exit. Note: When the light control is selected for startup, the light control takes priority to start, and the daily switch-on and switch-off times will be automatically generated. The switch-on and switch-off times cannot be set directly. You should modify the switch-on and switch-off times through the "Time Correction". "-" means the time is advanced, and "+" means the time is delayed.
