Product Description
Application Type DEM122 single phase impulse watt-hour meter is a kind of mechanism-electronic integrative new-style watt-hour meter which is designed and manufactured by our company on the base of type DDM862 single phase impulse watt-hour meter and developed for supplying collecting transcription meter system impulse group of formed direct ratio with using electricity quantity. The meter is suitable for measuring rated frequency 50Hz single phase AC active energy electric energy. Its technical performance are completely conform to National Standard GB/T15283-94 and international standard IEC60521. Functions and features The meter use type DEM072 single phase watt-hour meter as basal meter and add a impulse occurring device sampling by magnetoelectricity sensor. It has the following functions: Adjust impulse width, impulse output indication, anti-dithering, wide temperature working range (-40~80)high reliability and long life, can choose inner placed current as power supply electrical source.
