Application:
DDM862a single-phase impulse kilowatt-hour meter is a
kind of mechanism-electronic integrative new-style kilowatt-hour meter
which is designed and manufactured by out company and developed for
adapting townsman using electricity measuring and concentrative management
as multiplayer residence and storied buildings and 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 is completely conforming to National Standard GB/T15283-94.
Functions and features:
The meter use type DD862a single-phase kilowatt-hour
meter as basal meter and add a impulse occurring device sampling by
magnetoelectricity sensor. It has the following functions: adjust impulse
width, LED impulse output indication, high reliability and long life.
