LEM041 series electricity meter can directly and accurately measure the load active energy consumption in the three phase AC networks of rated frequency 50Hz or 60Hz. The LEM041 series electricity meter have multiple configurations for option, to be suitable with the various market demands. LEM041 series electricity meter have features with excellent long-term reliability, small volume, light weight, perfect appearance, easy installation, etc.

√ LEM041 series electricity meter ; 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.
√  LEM041 series electricity meter ; 10 pole width (modulus 12.5mm), complying with Standards JB/T7121-1993.
√  LEM041 series electricity meter ; Can select time-of-use metering in 3 tariffs. Can set 12 daily intervals. Can freely set the date in every month to read meter automatically. Can set single tariff at weekends.
√  LEM041 series electricity meter ; Can select 2 tariffs metering, equipped with the tariff setting port, if the input control voltage is 0 - 90 Vac, the setting tariff is F1. If the input control voltage is 150 - 400 Vac, the setting tariff is F2. Tariff transduction is controlled by the external timer or similar device.
√  LEM041 series electricity meter ; The meter with time-of-use metering in 3 tariffs has clock chip inside and maintenance free lithium battery inside. The battery capacity can be detected in real time and displayed, keeping the data for 12 months.
 LEM041 series electricity meter ; 7 digits LCD 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. The decimal of the data display can be set to be 1 or 2 digits.
√  LEM041 series electricity meter ; Can select the inside far infrared data communication port and RS485 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 other communication protocol.  
√  LEM041 series electricity meter ; S-connection (inlet wire from bottom and outlet wire on top) has two connection types: direct connection and CT connection for option.
√  LEM041 series electricity meter ; For CT connection meter, it is indirect reading or direct reading for option. For direct reading, there are 27 kinds CT rates to set, after setting CT rate, we can read the meter directly, no need multiplying the CT rate.
√  LEM041 series electricity meter ; The CT direct reading 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.
√  LEM041 series electricity meter ; With a non-volatile memory, keep the data permanently while the power is cut.
√  LEM041 series electricity meter ; Equipped with a polarity passive energy impulse output terminal, conforming to Standards IEC 62053-31 and DIN 43864.
√  LEM041 series electricity meter ; LEDs indicate separately the power state on each phase, the energy impulse signal, load current flow direction, current tariff state and data communication state.
√  LEM041 series electricity meter ; Automatic detection for the load current flow direction and will be indicated by LED.
√  LEM041 series electricity meter ; Measure the active energy consumption in one direction on three phases, which is not related with the load current flow direction at all, complying with Standards IEC 62053-21.
√  LEM041 series electricity meter ; The short terminal cover is made with the transparent PC, to reduce the installation space and is convenient for centralized installation.
