The LEM611 series smart meters are DIN rail three phase multifunctional energy meters. Recently we have researched and developed LEM611 series smart meters with complete independent intellectual property rights. LEM611 series smart meters technical performances completely conform to International Standards IEC 62053-21 for Class 1 three phase active energy meter and IEC 62053-23 for Class 2 three phase reactive energy meter. LEM611 series smart meters can directly and accurately measure all kinds of electrical parameters and the load energy consumption in three phase AC networks of rated frequency 50Hz or 60Hz. The LEM611 series smart meters have multiple configurations for option, to be suitable with the various market demands. LEM611 series smart meters have features with excellent long-term reliability, small volume, light weight, perfect appearance, easy installation, etc.

√  LEM611 series smart meters; 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). Two mounted methods above are optional for user.
√ LEM611 series smart meters; 10 pole width (modulus 12.5mm), complying with Standards JB/T7121-1993.
√ LEM611 series smart meters; Can set single tariff at weekends.
√ LEM611 series smart meters; 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.
√ LEM611 series smart meters;  Can record the electricity data for 12 months. Keep the data permanently while the power is cut.
√ LEM611 series smart meters; Can set the cycle display interval, the maximum cycle display is 48 data items. Can select the data item of display. The decimal of the electricity data display can be set to be 1 or 2 digits.
√ LEM611 series smart meters; The output impulse rate has 4 types: 0.01，0.1，1，10 kWh or kvarh/Pulse, which the user can set to any needed type, conforming to Standards IEC 62053-31 and DIN 43864.
√ LEM611 series smart meters; Equipped with far infrared data communication port and RS485 data communication port for setting meter or reading meter. Setting meter has password protection. The standard communication protocol complies with Standards DL/T645-1997, and the other communication protocol is also for option.
√ LEM611 series smart meters; S-connection (inlet wire from bottom and outlet wire on top) has two types: direct connection and CT connection for option. For CT connection 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.
√ LEM611 series smart meters; Direct connection meter is 6+1 (999999.1) LCD display.
√ LEM611 series smart meters; 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.
√ LEM611 series smart meters; LEDs indicate separately the power state, the energy impulse signal, the load current flow direction, current tariff state and data communication state.
√ LEM611 series smart meters; 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. complying with Standards IEC 62053-21 and IEC 62053-23.
√ LEM611 series smart meters; The short terminal cover is made with the transparent PC, to reduce the installation space and is convenient for centralized installation.
