Din Rail-type Energy Meter
YN40
Overview
YN40 type Three-Phase Four-Wire Active Electronic Energy Meter is a new type of three-phase electronic energy developed by our company using microelectric technology to measure electric energy, using imported special large-scale integrated circuits, applying digital sampling processing technology and SMT process and other advanced. This energy meter fully meets the relevant technical requirements of GB/T17215.321 -2008 national standard and IEC605J-21 international standard for 1-level three-phase active energy meters; it has the characteristics of good reliability, small size, lightweight, beautiful, advanced technology, etc.; and it has good anti-electromagnetic interference, low self-consumption energy saving, high precision, high overload, high stability,-electricity theft, long life; this meter is suitable for measuring the active electric energy of three-phase AC with rated frequency of 50Hz or 6Hz. It is suitable for fixed installation indoors, suitable for ambient temperature not exceeding -25~+55℃, relative humidity not exceeding 95%, and the does not contain corrosive gases and avoid dust, mold, salt spray, dew, insects and other effects.
