| 1 Phase 2 Wire electronic watt-hour meter Appearance and installation size Type：LTM12 product number：LTM12-1a weigt：about 1.2kg ☆ Product Brief Introduction The Single-phase Electronic Watt-hour
Meter adopts advanced microelectronics technique and SMT
manufacturing technology, its performance conforms to IEC61036
standard, this product is used for measuring single-phase AC active
electric energy whose rated frequency is 50Hz or 60Hz. It also owns
many advantages as high metering precision、high
sensitivity、reliable performance、wide load、low power
consumption、small volume characteristics etc. The single-phase
electronic Watt-hour Meter using glass cover and iron base, which
design is suitable for tropics regional climate and install
outdoors out of shelter. ☆ Function and features 1. Measure active electric energy, Do not need
calibrate for long-term operation. 2. Adopt special measuring chip of ADE7755； 3. Adopting latest electricity dedication
integrated circuit including digital multiplier overseas, greatly
improve dynamic working range of meter , making 10 multiple actual
overload； 4. Have good mistake linearity in the range of
5%Ib~Imax； 5. Few periphery component, simple
structure，low power consumption； 6. Adopting high reliability and long life
electronic component, So the Meter assume feature of high
reliability and long life； ☆ Specification and Technical Data 1. Rated
