Energy meter adopts microelectronics and digital processing technology to measure electric energy, internal integrated circuit is manufactured with precision SMT technology, with good electromagnetic interference resistance and stable performance. The use of high-strength flame-retardant fire-retardant material, high temperature does not deform, intelligent control chip, real-time power and power consumption at a glance, allowing you to easily manage the working status of power consumption. This energy meter can measure positive active energy in electric energy measurement, which is clearly displayed by LCD backlight screen, watt meter has low power consumption, high precision, high overload, electricity anti-stealing. The circuit board of the electric energy meter has clear and clear ordering, accurate measurement, backlit LCD screen, and the data can be seen clearly in a dim environment. It is suitable for families, rental houses, hotels, and office buildings. KWH meter circularly displays voltage, current, power and energy KWh, small size, light weight, 35mm DIN rail mounting.
