characteristic:

Measurement: Single phase power factor
● Display: A row of digital tubes (LEDs) display STN blue screen, wide viewing angle, high-quality, high-definition LCD screen display.
Communication: RS485 communication, MODBUS-RTU protocol. It has networking communication function.
● Input: 2-channel switch input (2DI).
Output: 2-channel switch output (2DO), 1-channel analog output (1AO).
Voltage transformers are required for AC500V and above

summary:

The digital intelligent single-phase power factor meter is suitable for measuring and displaying electrical parameters such as current, voltage, frequency, active power, reactive power, and power factor in power grids and automation systems. By setting the magnification on the panel, it intuitively displays the operating point parameters of the system's primary side. It has the advantages of high accuracy, good stability, and anti vibration, and can directly replace the original pointer type instrument.
