Summarize
Single-phase intelligent power meter can measure single-phase active power or single-phase reactive power in the power grid with high precision, and optional RS485 communication function and upper and lower limit alarm function. It has the characteristics of easy connection and installation, simple wiring, convenient maintenance, small engineering amount, field programmable setting input parameters, etc., and can complete the networking communication with different PLC and industrial control computers in the industry.
Peculiarity
Measurement: single-phase active power or single-phase reactive
power
Display: a row of LED digital tube display, high visibility
Communication: RS485 communication, MODBUS-RTU communication
protocol (optional)
Output: Two relay outputs (optional)
Expansion: Input signal can be directly from the current and
transformer, and the input parameter ratio can be programmed on
site
Application: Suitable for power grid, automatic control system,
mainly measure single-phase power parameters in power grid
