DTSD178 smart energy meter is designed and manufactured on the basis of stable power supply
technology, and has adopted the advanced large-scale integrated circuits technology, experienced
software algorithms, low power consumption design and SMT process according to the requirements of
international standards. The product is characterized by integrated functions of metering, display,
communication, detection, etc. It provides with functions of metering the import and export active
energy, the reactive energy of four quadrants and demand by time period accurately; metering voltage,
current, active and reactive power, power factors, etc. of three phases; detecting and recording over/low
voltage, over current, etc.; performing the function of remote and local meter reading, programming, etc.
It is widely used in grid gateway, power plants, substations, comprehensive energy measurement and
management of enterprises and institutions and TOU metering for industry users.
