1.General
PZ72-E is a kind of single phase power analyzer which can measures the data of single phase network. They comply EN 61326:2006 and EN 61010-1:2001.
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 Modbus-RTU; or they can output analog signal. With digital output, we can realize controlling other equipment remotely.
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.
