Ce Single Phase Digital Watt Meter

Product Description

Chapter 1.General introduction

 It is used to measure and display the direct reading of voltage and current values in the electrical line.The meter can be used as a general digital voltmeter/ammeter and can be installed with the analog output module to make it as voltage or current transmitter with the function of displaying primary circuit measurement value.You can also choose the relay output module to add the voltage,current limit alarm protection function. And can also select the multiple functional modules at the same time to make it with the functions of measurement,alarm,transmission and communication.
