Deskripsi
Three-Phase Intelligent Electricity Monitor
Model : AJ34
Brand : Shenzhen Electronic.Co.Ltd
Note: Measure three-phase four-wire phase voltage, current, frequency, power factor, active power, reactive power, active energy and reactive energy.
Product Introduction
The AJ34 high-precision intelligent comprehensive electrical quantity meter is primarily used in various industrial control and measurement systems. It conveniently measures various electrical parameters on three-phase, four-wire power lines. A single intelligent comprehensive electrical quantity meter can simultaneously replace multiple electrical parameter sensors, including current, voltage, frequency, power, power factor, and energy, reducing system costs and facilitating field wiring. In particular, its fully isolated processing technology significantly improves transmitter performance and contributes to increased system reliability. Its RS-485 bus output technology and MODBUS protocol enable the AJ series to connect to the same RS-485 bus as any industrial computer, facilitating programming and system expansion, allowing you to easily build your own measurement and control systems.
