【Upgrade Design】This upgrade electricity meter adopts a transparent shell, which is convenient to observe the working status of the electronic components inside the meter, and an eight-digit blue backlit LCD screen to display accurate data. When the main fuse is closed, the current meter reading will be recorded.  【Accurate Measurement】This electric meter can display power status (L1, L2, L3), pulse signal (400imp/kw/h, the pulse LED should flash when working), 8-digit backlit LCD display, 6 + 2 digit display (999999.11 kWh), the data is accurate, intelligent measurement chip, shown, accuracy class: 1.  【Small body, big function】 Can be installed directly in the terminal battery to meet the household multimeter network. The electricity consumption meter can be snapped onto DIN rails, installation options: meter cabinets, control cabinets, subdistribution panels without meter panel, footprint: 4TE (72 mm).  【Performance Stability】 The three-phase current meter has stable performance and can be used continuously in the range of -20 to 55 degrees Celsius. Insulating material housing, no electricity leakage, ensures your safe use and also saves space.  【Linear Power Supply】 Three-phase 4-wire electricity meter, the power consumption of the product is very small. The theoretical power consumption is at most 2W, are widely used in power measurement systems.
