1、 Overview

1.1 Purpose

AOB19 intelligent programmable digital display power factor and phase meter is a new generation of programmable intelligent meter, mainly used for real-time measurement and indication of power factor and phase (power factor angle) values in single-phase or three-phase power lines, and through RS485 interface or analog transmission output interface, it can be used to provide real-time measurement and indication of the power factor and phase (power factor angle) values in single-phase or three-phase power lines

Remote transmission of electricity measurement data.

1.2 Technical Features

Adopting modular design approach and full SMT production process

While real-time measuring and displaying power factor values, phase and frequency measurement values can also be viewed through the instrument keyboard

One channel analog transmission output function (optional), the output can be programmed to be 0-10mA, 0-20mA, 4-20mA at will

One way lower limit alarm output or two-way switch remote control output function (optional), alarm action delay time can be set arbitrarily within the range of 0-60s

RS485 communication output function (optional), using standard MODBUS-RTU communication protocol

It can simultaneously have one analog transmission, one lower limit alarm, and RS485 communication output functions

Two or four switch status detection function (optional), combined with RS485 communication to achieve "remote signaling" and "telemetry" of switch status

Maximum and minimum value viewing function
