DTM730 three-phase network parameter measuring instrument

DTM730 power parameter measuring instrument is a power parameter measuring instrument designed for the power monitoring needs of power systems, industrial and mining enterprises, public facilities, and smart buildings. It can measure all common power parameters, such as single-phase current, voltage, active and reactive power, and electricity. Since this power meter also has a complete communication network function, we call it a power parameter measuring instrument. It is very suitable for real-time power monitoring system. DTM730 has a very high cost performance, can directly replace conventional power transmitters and measuring instruments. As an advanced intelligent and digital front-end acquisition component, this series of power parameter measuring instruments have been widely used in various control systems, SCADA systems and energy management systems.
