smartESOX / smartESOX pro — three-phase transformer-connected electricity meters (class 0.2S / 0.5S / 1) for HV/MV/LV consumers
Country: Poland · Model: smartESOX / smartESOX pro
smartESOX and smartESOX pro are multi-tariff four-quadrant three-phase electricity meters for three- and four-wire HV, MV and LV networks. They connect semi-directly through current transformers (CT) or indirectly through CT and VT at 3×58/100 … 3×230/400 V, current Iref 1 or 5 A, Imax 6 A. They are installed for commercial and balance metering, and the pro version is aimed at high-accuracy measurement, including Smart Grid networks.

Description
The meter measures active, reactive and apparent energy, instantaneous, maximum and accumulated power, power transformer losses, voltages, currents, harmonics, frequency, THD and unbalance. It monitors voltage sags and swells, supply interruptions and overcurrent. Energy is metered in 6 tariff zones by a real-time clock, with at least 3 independent profiles, 7 event groups of 400 or more records each and up to 50 quantities in billing periods, up to 40 periods. Data is exchanged over DLMS/COSEM (PN-EN 62056-5-3, 62056-6-1/6-2) and optionally PN-EN 62056-21, through an optical port at up to 19 200 baud and two independent serial ports, 2 × RS-485 or RS-485 + RS-232, at 300 to 57 600 baud. A replaceable 2G/3G/4G or NB-IoT communication module, 3G/GPRS or Ethernet in the pro, is installed separately. When there is no mains voltage, the energy registers can be read from the display, which is powered by a replaceable AA battery.
How to choose
The accuracy class is chosen according to the metering purpose. smartESOX P has active energy class B or C, while the pro has 0.2S per EN 62053-22 and C per EN 50470-3, reactive class 3 or 2, and 2 and 0.5 % for the pro. The meter constant is 20 000 imp/kWh, insulation is 4 kV at 50 Hz, impulse 6 or 8 kV, and the clock is better than 0.5 s/day with external synchronization. EU MID (module B) and DLMS certificates are available.

FAQ
How is smartESOX connected to the network?
Semi-directly through current transformers or indirectly through CT and VT. Rated voltage is from 3×58/100 to 3×230/400 V, current Iref 1 or 5 A, Imax 6 A.
What communication interfaces does smartESOX pro have?
An optical port, two serial ports and a replaceable 3G/GPRS or Ethernet module. The protocol is DLMS/COSEM, optionally IEC 62056-21.
How many tariff zones does the meter support?
Six tariff zones based on the built-in real-time clock. At least three independent profiles with a configurable interval are also available.
Does the meter record power quality?
Yes, it monitors voltage sags and swells, harmonics, THD, unbalance, current flow without voltage and overcurrent. The power quality profile is optional.
