NPZM-40 National Highway Street Light Intelligent Centralized Energy-Saving Controller

            The NPZM-40 National Road Lamp Intelligent Centralized Energy-Saving Controller utilizes power electronics technology to achieve high-frequency chopping and voltage regulation. It intelligently provides the lighting system with dynamically adjustable voltage within the range of 0V to the input voltage, featuring stepless adjustment, a flicker-free and non-extinguishing regulation process, and a pure sinusoidal output voltage. It is compatible with both old and new light sources, extends the lifespan of light sources, optimizes the use of electrical energy from the grid, and achieves energy-saving goals. Based on practical usage, the energy-saving, voltage-reducing, and current-limiting remote control devices for street lamps, AIX-2C-100 and AIX-2C-60, achieve an energy-saving rate of over 30% for public lighting fixtures such as HID lamps, fluorescent lamps, and incandescent lamps.

NPZM-40 National Road Lamp Intelligent Centralized Energy-Saving Controller LCD Screen Manual Setup Operation Steps Explanation

Press and hold the confirm button, the screen displays "----", release the button, press the confirm button again, the screen displays "F1", press the plus or minus buttons until the screen displays "F2", press the confirm button to enter function settings.

The screen displays "CH", press the confirm button once, the screen displays "oFF" or "on", use the plus/minus buttons or the confirm button to choose to enable this function "on" or disable it "oFF".

Press the return button, the screen displays "-CH-" indicating the function is enabled. Then, use the plus/minus buttons to select the setting, for example, 1, the screen displays "C-01", press the confirm button once to enter settings, the screen displays "L01-" or "L01", the presence of "-" indicates the channel is open, and the channel indicator light will correspondingly light up. Press the confirm button to enable or disable the channel, use the plus/minus buttons to select the channel to set. Among these, "C-41" corresponds to all off, "C-42" to all on, "C-43" to pause, and "C-44" to mute.

The National Road Lamp Intelligent Centralized Energy-Saving Controller can select this function through computer global settings and directly call the pre-set relay channel parameters.

Technical Features of the National Road Lamp Intelligent Centralized Energy-Saving Controller:

The device's low current value is pre-set in the program before leaving the factory. For devices of 100A and above, the starting current is 10A, and the automatic low current is 5A; for devices below 100A, the starting current is 10%, and the automatic low current is half of the starting current.

Fully automatic voltage-limiting energy saving and voltage stabilization characteristics;

Easy installation, basically maintenance-free, no need to modify the power distribution lines, simply connect in series with the existing circuit. The energy saver automatically saves energy after being put into operation.

Bypass start: Provides full voltage supply for a certain period upon start to ensure normal use of the lamp, then automatically enters energy-saving operation mode; Soft start: Achieves the purpose of starting current through the starting voltage while ensuring the lamp can be used normally, thereby extending the lamp's service life. Automatically enters energy-saving mode after starting, with adjustable start time.

The device features an automatic memory function, capable of storing fault codes and operational data from 10 minutes before a fault occurs.
