1. General
ACR320 Series power analyzer specializes in measuring the data of all kinds of AC networks, such as the currents, the voltages, the powers, the energies etc... It may be used for local display, or it is connected with the control equipment in measuring and controlling system.
They are a kind of programmable analyzer. With the 4 key on the front, we can set their parameters according to the network which we measure. They have many option functions. They can be equipped RS-485 communication with Modbus-RTU protocol; or they can output analog signal or relay signal.
They are a kind of analyzer with excellent cost performance, since they regroup the functions of traditional electric transmitter and digital meters. Therefore they are widely being used in kinds of control system, SCADA system and power management system.
