MTK3-80KVA, MTK3-160KVA, MTK3-50KVA factory area street lamp step-down voltage stabilization and dimming devices are high-performance products developed on the basis of microprocessor technology and modern advanced power electronics technology. They can effectively achieve step-down and voltage-limiting functions, extend the service life of lamps, reduce maintenance costs, decrease the workload of maintenance personnel, and the energy-saving effect can reach 10%-45%*. The investment is small and the results are quick. The intelligent lighting control device saves energy: It overcomes excessive power consumption caused by high voltage, and users can also preset time periods and lighting brightness. The energy-saving effect reaches 20% - 40%. Zhejiang Juchuan Electrical Technology Co., Ltd. O57727877837.
Key points for selecting intelligent voltage-regulating and energy-saving devices for factory street lamps:
1) For occasions with a small capacity of the power supply transformer, a short power supply line, and relatively single electrical equipment, the energy-saving device can be directly installed beside the lighting distribution cabinet in the main power distribution room to achieve centralized energy saving. The investment cost is low and the energy-saving effect is obvious.
2) For areas with a large capacity of the power supply transformer, a long power supply line, and relatively complex electrical equipment, decentralized installation is suitable to achieve the rationality, safety, and effectiveness of energy saving. According to the user's power consumption situation, energy-saving devices can be installed in different control loops of the entire lighting system, such as energy-saving control by building number, energy-saving control by floor, and energy-saving control by area. The energy-saving device can be installed in the main power distribution room, distribution shafts, distribution boxes, etc.
3) When selecting the energy-saving device, take the working current of all electrical equipment in the lighting circuit during operation as a parameter, and consider the rated capacity of the circuit breaker in this circuit. The energy-saving device should be installed near the lighting system switchgear, vertically on a stable and reliable foundation; the shell should be reliably grounded to ensure safe use; leave enough installation space and operating space.

Functional advantages of MTK3-80KVA, MTK3-160KVA, MTK3-50KVA factory intelligent street lamp voltage regulation energy-saving devices
1. The intelligent lighting voltage stabilizer achieves energy-saving effects by setting and managing the illuminance in different environments at different times through various intelligent setting control methods and control elements.
2. The intelligent lighting voltage stabilizer can also use soft start and soft shutdown technologies to avoid damage to the light source caused by inrush current.
3. Allowing the lighting system to start smoothly in a "slow ramp" manner under maximum load can greatly extend the service life of the lamps by 3 - 4 times.
4. When a fault, overload, or over-temperature occurs, the bypass is activated, directly connecting the lighting of this phase to the power supply voltage to maintain normal lighting. The bypass unit is a static device, with each phase being independent and equipped with a magnetic-thermal protection switch.
5. Convert the illuminance into a light scale, and set the light scale for turning the lights on and off in the software.
6. The energy-saving controller has an adjustable full-voltage preheating start time for lamps such as sodium lamps, allowing the lamps to preheat more fully and smoothly transition to the normal working state.
7. Reserve a set of normally open contacts controlled by a clock for special control.
8. The program stored in the microprocessor can control all the operating modes of the equipment, detect the output voltage, bypass, and operating conditions of the power-saving system, transmit the instructions required for correcting the voltage, and realize the conversion between the nominal voltage and the power-saving voltage through controlling external signals.
MTK3-80KVA, MTK3-160KVA, MTK3-50KVA Factory intelligent street lamp voltage regulation and energy-saving device common problem handling methods.
1. Drying standard:
The street lamp renovation lighting voltage stabilizer should not contain moisture.
The insulation resistance should not be less than 70% of the factory data.
The dielectric loss tangent should not be greater than 130% of the factory data.
2. The street lamp renovation lighting voltage stabilizer should be dried in the following situations:
Replace the winding or insulation during maintenance.
When repairing or installing the device body, the device body is exposed to the air for more than the corresponding specified time.
The winding of the street lamp renovation lighting voltage stabilizer is damp according to the measurement of insulation resistance and absorption ratio.
