Digital electricity is a method of delivering power in rapid, discrete pulses rather than as a continuous flow. Between each pulse, the system checks for faults like short circuits or human contact, shutting down in microseconds if something is wrong. This makes it possible to send relatively high power over simple, low-voltage wiring while maintaining the safety profile of a low-voltage system.
How It Works
Traditional electrical systems deliver a continuous stream of power. Digital electricity breaks that stream into small, controlled “energy packets,” brief bursts of power separated by tiny gaps. During each gap, the system’s transmitter runs a safety check on the line. If it detects an abnormal condition (a cut wire, moisture, or someone touching an exposed conductor), it stops sending power before the next packet goes out. The entire check-and-send cycle happens so fast that connected devices receive what feels like uninterrupted power.
The concept borrows from how data networks operate. Just as the internet sends information in addressed packets that are routed, verified, and reassembled, digital electricity sends energy in finite, managed amounts. Loads on the system use a request-grant protocol: a device requests the energy it needs, and the source grants and delivers that specific amount. This two-way communication means the system always knows what’s connected, how much power it needs, and whether the line is safe.
The Hardware: Transmitters and Receivers
A digital electricity system has two main components. The transmitter (sometimes called the head-end unit) sits near the power source. It converts standard AC or DC power into pulsed energy packets, manages the safety-checking cycle, and controls how much energy goes out on each line. The receiver sits at the other end, near the device being powered. It reassembles the incoming pulses into steady, usable power for the connected load. Together, these two endpoints create an intelligent power link that constantly monitors itself.
Power and Distance Compared to PoE
The most familiar technology in this space is Power over Ethernet (PoE), which sends low-level power alongside data over standard network cables. PoE tops out at about 90 watts and can only reach 100 meters on Cat6 cable, with real-world delivery dropping to around 70 watts at that maximum distance. That’s enough for a security camera or a wireless access point, but not much else.
Digital electricity pushes well beyond those limits using the same low-voltage wiring practices. The system can deliver up to 2,400 watts at 100 meters, 2,000 watts at 300 meters, and still provide 400 watts at distances up to 2 kilometers. That’s enough to power LED lighting across an entire building, run point-of-sale terminals in a retail store, or supply equipment in locations where running traditional high-voltage wiring would be expensive or impractical.
Why Safety Changes the Installation Rules
Conventional high-voltage wiring (Class 1 power in the National Electrical Code) requires licensed electricians, metal conduit, specific routing away from data cables, and inspections at every stage. These requirements exist because a continuous 120V or 277V circuit can deliver a lethal shock and start a fire. Digital electricity sidesteps much of this. Because the system checks for faults between every pulse and shuts down before dangerous energy levels can build up, it behaves more like a low-voltage system from a safety standpoint.
The 2023 edition of the National Electrical Code (NFPA 70) recognized this with a new Article 726, which created a formal “Class 4” power classification for fault-managed power systems. This was a significant regulatory milestone. Class 4 systems can carry higher power levels than traditional low-voltage (Class 2) circuits while still qualifying for simplified wiring methods. Digital Electricity is also classified as a Limited Power Source under UL 62368-1, making it suitable for supplying Class 2 circuits under NEC Article 725.
Adoption varies by location. Class 4 circuits only become an enforceable installation method once a local authority adopts the 2023 code, and that rollout is still in progress across the United States.
Practical Applications
The combination of higher power, longer range, and simpler wiring makes digital electricity especially useful in commercial buildings. LED lighting is one of the most common applications: rather than running dedicated high-voltage circuits to every fixture, installers can use lightweight cable that also carries control signals, making it easy to add dimming, color tuning, and occupancy sensing without extra wiring. Office buildings, warehouses, and retail spaces have adopted this approach to reduce installation complexity.
It also fits well in environments where traditional wiring is difficult to retrofit. Historic buildings with plaster walls, outdoor installations spanning long distances, and temporary setups like event venues all benefit from a system that doesn’t require conduit or the same level of electrical trade labor. The intelligent request-grant protocol also means the system can monitor energy use at each endpoint, giving building managers granular data on power consumption without separate metering hardware.
Limitations Worth Knowing
Digital electricity is not a replacement for all conventional power. At 2,400 watts maximum, it can’t run heavy loads like HVAC systems, commercial kitchen equipment, or industrial machinery. It’s designed for distributed, moderate-power loads: lighting, sensors, displays, access control, and similar systems. The technology also requires proprietary transmitters and receivers, so you’re working within a specific vendor ecosystem rather than pulling commodity parts off a shelf. And until your local jurisdiction adopts the 2023 NEC, the regulatory framework for Class 4 installations may not be in place, which can complicate permitting.
