What is the energy-saving control system of street lamps?
2. Intelligent energy saving can be automatically controlled for more than 8 periods, and multi-period voltage, energy saving rate and illumination can be adjusted by users.
3. Contactless voltage regulation. It is not recommended to use contactor contacts to adjust voltage (flashing lights to turn off lights).
4. The voltage regulation is stepless and continuous, and the step value of each regulated voltage is less than1v.. During the adjustment process, the light does not flicker, and there is no flash impact of the power grid.
5. When adjusting the voltage, the adjustment speed can be set by the user to adapt to the slow change of brightness and the stability of lamp arc.
6, turn on the light with full voltage preheating, preheating time (10 minutes or more) can be set and adjusted by software.
7. The adjustable range of the output voltage of the economizer is 160-220V.
8. The adaptive range of the input voltage of the economizer: 160V-260V.
9, three-phase independent adjustment, can adapt to the three-phase serious imbalance.
10, which has the functions of manual bypass and fault automatic bypass, and can switch from energy-saving state to bypass and bypass to power-saving state without flashing or turning off the lights.
1 1, with unconditional lighting function, overcurrent, overvoltage, undervoltage and overheating can be automatically bypassed, and fault codes can be recorded for maintenance. The lights cannot be turned off when the equipment is damaged, and the life and normal operation of street lamps will not be affected when the equipment fails.
12. Energy-saving equipment should be installed outdoors. The box body is made of steel plate with a thickness of 2mm, which will not be oxidized in 10 years. The protection level is not less than IP33, and it is equipped with air cooling system. The switch in the box shall be of high quality brand.
13, standard sine wave voltage (same as input voltage waveform), no distortion; It does not increase the current harmonics of lighting load (double-peak current waveform of sodium lamp) and the total harmonics of input current.
14, the power factor can only be increased but not decreased.
15, with monitoring switch light interface and monitoring voltage regulating interface, the central control room can send voltage regulating commands and switch lights.
16, with automatic reset function. When power is cut off and power supply is resumed, preheating will be started at full voltage, and it will be automatically adjusted to enter the working state according to the working setting after starting.
17, with lightning protection device and safety grounding.
