DF2LP26 is a high-precision, multifunctional digital power meter for general AC applications. It provides all basic metering functions, including current, voltage, frequency, power factor, power, active energy, as well as voltage crest factor. This instrument is widely used in industries such as power generation, power distribution, and automation control. In this paper, the application field and working principle of the DF2LP26 will be discussed in detail.

The DF2LP26 is mainly used in power metering, load monitoring, power quality analysis, energy conservation and efficiency improvement, as well as intelligent electric power systems. As a multifunctional power meter, it can accurately read out the power parameters of a circuit, such as active power, active energy, reactive power, reactive energy, etc. In addition, the DF2LP26 can also provide further analysis of the power quality, such as current and voltage frequency deviation, voltage flicker, harmonics, and other potentially destructive physical phenomena.

In order to accurately measure the power parameters, the DF2LP26 adopts a highly accurate hall-effect current sensor and voltage sampling device. The measurement data of the electric current and voltage are sampled in real time, and the power parameters are then calculated in the digital processor module. After the calculation, it will be displayed on the LCD screen which can be viewed by the user. Additionally, the power metering parameters can also be transmitted through RS485 communication port.

Besides the real-time power metering function, the DF2LP26 also supports IO (input-output) function, alarm function, and function setting. For the IO function, the DF2LP26 provides four configurable digital inputs and two analog inputs for various signal collection and monitoring applications. For the alarm function, it can monitor certain metering points and issue an alarm when certain conditions are met, which is convenient for users to timely response to abnormal power situations. For the function setting, the user can set parameters such as display and communication according to their own needs, making the instrument even more user friendly.

To sum up, the DF2LP26 is a digital power meter with versatile functions, wide applications, and advanced metering innovations. Its reliable and accurate metering functions enable users to effectively detect and respond to power abnormalities, and its powerful features and flexibility make it ideal for a variety of ac power metering applications. This makes it an indispensable instrument for today’s smart power systems.
