Revitalize public road lighting systems with our high‑performance NEMA smart street light controller, built strictly according to international NEMA C136.41 industry standard. Thanks to the standard NEMA socket design, installation becomes true plug‑and‑play. No extra wiring or complicated field modification is required. Site technicians can finish hardware replacement rapidly, greatly cutting construction time and labour cost for municipal renovation projects.
This modular controller integrates a full set of measurement and sensing capacities. It precisely measures core electrical parameters including voltage, electric current, output power and cumulative energy consumption. Real‑time environmental condition monitoring is supported. Built‑in inclination sensor continuously tracks lamp pole status, sends instant alarm notifications once abnormal tilt occurs, helping operation teams discover hidden safety risks ahead of lamp‑pole collapse accidents.
Equipped with GPS, Beidou and multi‑mode GNSS positioning module, the device obtains accurate satellite time, automatically calculates local sunrise and sunset time for automatic lighting schedule execution. The hardware embeds real‑time clock with calendar function to guarantee stable timing even when network connection is temporarily lost.
For communication flexibility, multiple mainstream IoT communication options are fully available: NB‑IoT, LoRaWAN, LoRaMesh, PLC, as well as dual‑mode combined communication. Project designers can select the most suitable solution according to site coverage condition, distance requirement and existing network infrastructure.
Zero‑cross switching relay technology is adopted inside the controller. It effectively reduces electric impact during relay action and extends the whole relay service life. IP66 high‑level ingress protection makes the unit fully resistant to rain, dust and temperature fluctuation. It can run stably all year round under harsh outdoor conditions, from high‑temperature summer to cold winter weather.
Open and secure API interfaces are reserved for system integration. System integrators and solution providers can connect this hardware smoothly to self‑developed or third‑party IoT cloud management platforms. Once connected, operators can achieve remote group management of thousands of street‑light nodes: remote stepless brightness adjustment, unified parameter configuration, remote fault diagnosis and automatic alarm push. Manual on‑site inspection frequency can be largely reduced.
We provide reliable 5‑year product warranty for all controllers. Deploying this smart hardware brings multi‑layer value for city administrators. First, it reduces routine maintenance expense and manual workforce input. Second, scientific dimming strategy delivers obvious power‑saving results and creates considerable economic benefits. Third, lower total power consumption supports local carbon‑reduction targets and accelerates progress toward carbon neutral urban construction.
This product fits wide application scenarios: urban road lighting upgrade, newly‑built smart city construction, suburban highway lighting, park and square public lighting, industrial park outdoor lighting. It works perfectly for government bidding projects, city‑wide lighting renovation and commercial smart‑lighting tenders.
