ORNO - 3-phase energy meter with MID, 80A, 4,3 modules, DIN TH-35mm OR-WE-531
The 3-phase energy meter with a maximum current of 80A is a modern measuring device designed for precise monitoring of electricity consumption in three-phase installations. The meter can be used for commercial, industrial and domestic applications where accurate and reliable readings are required.
The meter operates in systems with a rated voltage of 3x230V or 400V AC and a frequency of 50Hz, enabling direct energy measurement without the need for current transformers. The device records active, consumed and emitted energy. This allows for comprehensive monitoring of energy flow in both directions. A minimum measurement current of 0.25A ensures high sensitivity of the device even at low load, and a starting current of 0.02A allows even small current draws to be recorded.
The digital LCD display (6+2 digits) with a backlit allows comfortable readings even in low light. The unit also has an active energy sub-meter reset function, particularly useful in situations requiring periodic resetting of readings.
Designed for mounting on a TH-35mm DIN rail, it ensures easy installation in standard switchboards. The 76x100x65 mm enclosure accommodates 4.3 DIN modules as standard. The maximum cross-section of the connection cables is 35 mm².
The meter supports the IR protocol in accordance with EN 62056-21.
It is possible to set 27 different parameters to be displayed on the LCD screen. This requires the use of a USB optical head (OR-WE-518) to enable communication between a PC (Windows) and electricity meters equipped with IR optical ports. A simple application allows the data meter to be downloaded and programmed (including setting tariffs). Baud rate: 300, 600, 1200, 2400, 4800, 9600, 19200 bits/sec. Operates in accordance with IEC 62056-21 (IEC1107).
The meter has been designed in accordance with standards: EN 50470-3:2022, EN IEC 62053-21:2021, IEC 62052-11:2020, IEC 62052-31:2015. Compliance with MID 2014/32/EU allows the meter to be used in commercial spaces where certified equipment used for billing is required.
