Two-way electricity energy meter - digital, three-phase, 4-module with reset function, MID, SIMLIC, LS-3FB 85403010

Intelligent energy measurement in photovoltaic installations and beyond

This three-phase, bidirectional SIMLIC LS-3FB energy meter is a reliable solution for precise measurement of energy consumption and production. The device works perfectly in both industrial and household installations, and especially in photovoltaic systems, where it enables accurate settlement of energy fed into the grid. Thanks to the ability to measure both consumed and produced energy, it allows for full control over the energy balance.

The meter indicates active power [W] and active electrical energy [kWh] – both imported and exported. Its compact housing (4 modules) makes it easy to mount on a TS 35 rail in standard electrical panels. The reset function allows for easy zeroing of the meter readings, which is particularly useful for cyclical billing.

Precision and compliance with standards

The device meets the requirements of the MID (Measuring Instruments Directive), which guarantees the legality of measurements and the possibility of using it for billing purposes with energy suppliers. Accuracy class 1 ensures high reading accuracy, and the digital LCD display makes it easy to read measurement data. Additionally, the meter has an impulse output, which allows integration with monitoring and remote data reading systems.

The meter's design has been designed for durability and reliability. The housing with a protection degree of IP51 protects against external interference, and a wide operating temperature range (-25°C to +55°C) allows it to be used in various environmental conditions. The wire cross-section of 4…25mm² ensures compatibility with most electrical installations.
