Three-phase energy meter

Description

Three-phase electrical energy meter with indirect measurement, 5(10)A (, CEM-C31), direct measurement 65 A (CEM-C21) or single-phase energy meter (CEM-C10).
Built-in LCD display (7 digits) with rotating screen system. Features built-in RS-485 communications. Also features
2 buttons (1 sealable button) for viewing all the measured information.
Other features include:

• MID certification, module B+D (depending on the type)
• Class 1 active energy (Class B, in accordance with MID), Class 2 reactive energy
• Complies with the EN 50470 (MID European standards) or IEC 62052-11 standards (international standards), depending on the type.
• Compact size (CEM-C10: 2 modules, 36 mm, CEM-C21 y CEM-C31: 4 modules, 72 mm)
• Resettable partial meter
• 1 programmable impulse output, in accordance with DIN 43864 (CEM-C10, CEM-C31-T1, CEM-C21-T1 models)
• 1 Digital input for Tariff selection and impulse count (CEM-C31-D, CEM-C21-DS)
• Indicates bad connections on the screen
• Energy storage, even in the case of bad connections

Applications

• Redundant meter for verifying the energy allocated by the energy provider.
• Energy consumption report sent to a remote system (PLC/BMS).
• Cost control for achieving a high consumption/unit ratio in industrial processes.
• Display of electrical parameters (V, A, kW, kW·h, PF, etc.), per phase and three-phase.
