There is a considerable gap between equipment, meters, and their electricity usage, resulting in significant loss rates. Before the advent of the DIN Rail Power Meter, the lack of proper measurement and electrical optimization had been a difficult problem to solve. DIN stands for Deutsches Institut fur Normung, which means German Institute for Standardization. DIN became the official symbol of technical standardization in Germany in the 1970s.

　　Until recently, the interrelationship between supply and demand in the energy sector has been difficult to control and understand. Several key factors are critical for optimal power measurement. However, only two stand out: accurate energy consumption measurements and user power usage. Neither can be achieved with traditional induction meters, which is where the DIN Rail Power Meter comes into play.

　　During a fixed period of time, the DIN Rail Power Meter measures electricity usage to provide a benchmark for electricity prices. The DIN Rail Power Meter achieves significant workload reduction while optimizing energy consumption efficiency and balancing supply and demand, following two simple rules, if the power output is sufficient, the price can drop, encouraging users to use more electricity. However, if the power output is insufficient, the price will rise, thereby reducing the incentive for users to use electricity.
