PTK-UEC6C-X 6A three phase 3 or 4 wire programmable energy meter

General features

4 DIN modules energy meter for the energy measurement in industrial and civilian application, available with MID certification suitable for billing. Combined with different external modules, the meter can communicate with other systems. COM modules are available for the most common field protocols.

Besides the energy, the meter can measure the main electrical parameters and makes them available on the IR port. The LCD display shows the energies and the instantaneous powers.

The meter is built according to EN 50470-1 standard. The active energy is compliant to IEC 62053-22 class 0,5 S, but for MID certified device it moreover fulfills class C requirements according to EN 50470-3. The accuracy of reactive energy is compliant to IEC/EN 62053-23 class 2.

Wide backlighted LCD display with clear graphic symbols comprehensible at a glance. Metrological LED on front panel and sealable terminal covers. Available versions with different voltage working range for the connection on 3 or 4 wire network, suitable for balanced or unbalanced loads. The analysis of the MTBF values, the accurate selection of components and the reduction of the internal working temperatures together with strict production and control standards guarantee a product with an excellent quality and a long lasting reliability.

Applications

• Totalization of the electric energy in the industry for each single line or machine.
• Measurement of energy generated by renewable sources such as solar, eolic, etc.
• Accounting and billing of consumptions in camp sites, malls, residential areas, naval ports, etc.
• Totalization of the electric consumption in hotels, congress centers, exhibition fairs.
• Accounting of the consumptions in buildings with executive office services.
• Internal allocation of the consumptions in timeshare civilian and industrial buildings.
• Realization of energy monitoring systems.
• Remote survey of the consumptions and compute of the costs.
