2.Product introduction

 

This series digital display voltmeters are used to measure single phase or three phase AC voltage in low voltage distribution system. They are equipped with analog output, relay output, digital input and communication supporting Modbus-RTU protocol. Their transmitting ratio also can be changed through programming. There are different choices of outline size for this kind of meters. So they are suitable to replace analog pointer voltmeters.

This series digital display AC voltmeters have high environment adaptability because their working temperature range is -40~70℃ and EMC better than III level. They can be applied in control systems, distribution automation systems, industrial automation systems and intelligent buildings.
