1.Measure the active energy and reactive energy consumption on single phase or three phase AC power grid of rated frequency 50Hz or 60Hz,complying with Standards IEC 62053-21 and IEC 62053-23.
2.Measure the electrical parameters, like forward active energy, reverse active energy, forward reactive energy, reverse reactive energy, active and reactive maximum demand, real-time active and reactive and apparent power, real-time phase voltage and phase current and real-time frequency and real-time power factor, etc.
3.Can time-of-use metering in 4 tariffs. Can set 8 - 12 daily intervals. Can freely set the date in every month to read meter automatically. Can set single tariff at weekends.
4.Can freely select the block interval demand (default) and sliding-window demand. The demand interval can be set within 1-99 minutes. Automatic resetting the maximum demand or manual resetting for option.
5.Has clock chip inside and maintenance free lithium battery inside. The battery capacity can be detected in real time and displayed.
6.Can record the electricity data for 12 months. Keep the data permanently while the power is cut.
7.LCD display with two options: cycle display (default) or push-bottom display item by item. Can set the cycle display interval. Can select the data item of display.
8.Equipped with 2 polarity passive impulse output terminals: active energy and reactive energy, conforming to Standards IEC 62053-31 and DIN 43864.
9.LEDs indicate the power supply state, energy impulse signal, load current flow direction and the data communication state separately.
10.Equipped with RS485 data communication port and (or) far infrared data communication port for meter setting or reading meter. The meter setting has password protection. The communication protocol complies with Standards DL/T645-1997, can also select the Modbus-RTU communication protocol.
11.CT connection three phase meter, there are 27 kinds CT rates to set, after setting CT rate, we can read the meter directly, no need multiplying the CT rate. The CT connection meter is 7 digits LCD display: 5+2 digits (only at CT rate is 5:5A) or 7 integers, which is depended on the setting CT rate.
12.Available as 35mm DIN standard rail mounted, conforming to Standards DIN EN 50022, as well as front PANEL mounted (the center distance between two mounting holes is 63mm or 67mm). Two mounted methods above are optional for user.
13.LEM511 series width is 6 pole and LEM611 series width is 10 pole (modulus 12.5mm), complying with standard JB/T7121-1993.
14.Milk white flame retardant PC meter case and internal structure parts and the ClassⅡinsulation protection design, with the characteristics of moistureproof, flame retardant, thermostability, good weather resistance, high rigidity and excellent insulation property, etc., to ensure a longer service life and a more stylish appearance.
15.The short terminal cover is made with the transparent PC, to reduce the installation space and is convenient for centralized installation.
