Htew Series electric energy meters
Adopting AC sampling technology, can measure many single phase or three phase grid electrical parameters such as current, voltage, power, electric energy etc. directly or indirectly. It can be used for local display, and also can be connected with the control equipment to form measuring and controlling system.
Fitted with RS-485 communication port, adopting Modbus-RTU protocol. Meters can switch electric parameter signal into standard analog output, with four-channel switching input / two-channel switching output. Based on different requirements, by keys on the faceplate, electric parameters for transformation ratio, alarm, communication etc. can be set up and controlled.
