1. Product introduction
Guide rail type electric energy meters are designed and produced according to user’s real
electricity consumption situation by adopting advanced energy measurement IC and using digital
sampling processing and SMT technologies. They are used to measure the real-time parameters of
voltage, current, power, power factor, frequency and demand. They also have the functions such as
energy measurement, SOE, pulse and communication. This series of energy meters adopt modularity
structure with the features such as small volume, convenient installation and reliable working.
