ZE314

The ZE314 electricity meter series is a poly-phase single- or double-tariff, modern, fully programmable electricity meter for monitoring of electricity consumption in low-demand areas. It is able to meet the monitoring requirements of active energy in accuracy class A or B as per standard EN 50470-1 and EN

50470-3 in both energy import and export directions. Its structure is designed to connect to the network TN-C.

The electricity meter is equipped with LED calibration constant adjustable from 500 to 10.000 imp./kWh. The meter registers separately import and export of electricity. Direction of energy flow is indicated by arrows.

Identification of the firmware version, incl. CRC is possible to determine from the register 0.2.0. This register is displayed on the LCD after switching on the electricity meter. The meter calibration is performed in the production based on the findings of accuracy measurement and insert of calculated calibration constants. The electricity meter has no mechanical adjustments.

Against overvoltage the meter is protected by voltage inputs. Any mismatch during wires installation is indicated on the LCD. Size of digit is 8 x 4 mm.
