Background
Load-side distribution units are widely scattered across factory workshops, commercial buildings, industrial parks, oil fields, etc., with large quantities and dispersed locations.
Traditional distribution boxes only offer local switching capabilities, lacking remote data acquisition and unified supervision.
This results in slow fault response, fragmented energy data, and high maintenance costs.
As digitalization of asset management advances, a wireless, no‑wiring, and scalable smart monitoring system is urgently needed.
Pain & Value
Your Pain Points
Dispersed energy & safety data cannot be centrally managed

Solution
End‑Edge‑Cloud Integrated Smart Monitoring for Dispersed Distribution
Perception Layer
ADW300A wireless meter captures full electrical parameters (V, I, temp, leakage) and supports Bluetooth debugging – quick configuration without opening covers.
Network Layer
Lora/LoraWAN/4G/Wi-Fi wireless transmission with breakpoint resume and power‑failure reporting – no communication cables required.
Platform Layer
Acrel cloud platform centrally manages all dispersed distribution units, offering real‑time monitoring, energy analysis, and active alarming.
With wireless metering terminals as the core and cloud‑based centralized management, it requires no wiring retrofit, enables quick single‑point deployment, and simplifies on‑site maintenance via Bluetooth debugging – significantly reducing implementation difficulty and operational cost for large‑scale intelligent end‑of‑line distribution.

Application
Compliant with DEWA and SEC distribution automation standards, enabling wireless voltage, current, and temperature monitoring for urban ring main units and public distribution cabinets – no power shutdown required. Delivers branch circuit power quality analysis, helping utilities quickly locate ground faults and overload risks.
For high‑current equipment panels serving drilling rigs, mine hoists, and large tower cranes, using 4G wireless communication and split‑core CTs – quick retrofitting without power interruption. Real‑time monitoring of three‑phase current, active power, and cable temperature prevents overload trips and reduces unplanned downtime costs.
For scattered end‑line distribution boxes serving high‑power loads such as electric furnaces, compressors, and fans in workshops, using LoraWAN self‑organizing network (1 km coverage) – no cabling required. Provides demand analysis and harmonic monitoring (2nd‑63rd order), helping enterprises optimize production scheduling, reduce demand charges, and diagnose equipment abnormalities.
For high‑current distribution cabinets serving common areas such as lighting, HVAC, elevators, and pumps in malls and office towers, using 4G/Wi-Fi wireless transmission – retrofit‑free connection to Acrel cloud platform. Enables sub‑metering of common area energy consumption and cost allocation, while monitoring leakage current and temperature on each circuit to ensure electrical safety in crowded spaces.
Choosing the Acrel integrated solution establishes a smart monitoring system for load-side distribution units (ring main units, construction site panels, industrial power cabinets) that supports grid reliability and operational continuity – compliant with DEWA/SEC distribution automation expectations.
It transcends traditional manual inspection and reactive maintenance by enabling wireless real‑time monitoring of current, voltage, temperature and leakage, plus breakpoint resume and Bluetooth debugging – delivering proactive fault location, verifiable energy savings, and remote management for widely scattered, high‑current end‑of‑line cabinets.
Make every distribution unit Visible, Intelligent and Secure.
