1.Product introduction

 SFERE720A/B multi-function power meters can measure voltage, current, frequency, power, power factor, energy, harmonics and demand, record SOE events, and realize off-limit alarm. They also have the functions such as communication, digital input, relay output and energy pulse output. As an advanced smart digital front-end acquisition components for grid, they are widely applied in many kinds of control systems, energy management systems, substation automation systems, power distribution automation systems, smart distributors and switch cabinets. This series of products provide many wiring methods and convenient operation methods which can meet different requirements at field.
