Product Description

AT161Y Digital Three Phase Multi-functional Power & Harmonic Analyzer is an ideal device for power monitoring. The meter can measure and display current, voltage, frequency, active power, reactive power, apparent power, forward and reverse active power, forward and reverse reactive power, power factor, compound rate, 2-31th harmonics in the power grid. It is suitable for the distributed detection of transformers, generator sets, capacitor sets and motors, and the on-site monitoring of power grids and automation control systems.

This series of multi-function power meters can replace many traditional analog or digital measuring instruments (such as ammeter, voltmeter, power consumption meter, power factor meter, frequency meter, etc.), which can greatly reduce the system cost, facilitate field wiring and improve the reliability of the system. The multi-function power meter is equipped with a serial port, allowing connection to an open computer network; the application of Modbus communication protocol makes it easy for the computer to program settings or read data

Main features:

• Highly accurate power measurement
• Modular design, flexible configuration of each function
• Adjustable voltage and current ratio
• Three-phase voltage/current total harmonics and 2nd~31st sub-harmonic analysis
• Parameter settings are permanently stored in power failure
• Support RS-485 communication
• Adopt AC/DC dual-use power supply, high and low voltage isolation
• LCD display
• With various sizes, easy installation and wiring
