Description:
The Landis+Gyr E850 ZMQ202 is a high-precision, four-quadrant grid and generation meter for power stations, wind and solar plants, transmission and distribution substations, railway supplies and large grid-connected industrial consumers. This version is the three-phase four-wire, 1 A CT-connected Class 0.2S meter in the f9 rack-mount metal housing with an Essailec plug-in connector, configured with the C.8 software package (active, reactive and apparent energy, load profiles, power quality) and an Ethernet communication module for DLMS/COSEM remote reading. It plugs directly into the matching ZMQ f9 rack socket set (sold separately), allowing meters to be exchanged or tested without disturbing the wiring.
 
Key Features:
Class 0.2S active energy (IEC 62053-22) and Class 0.5S reactive energy (IEC 62053-24), 1 A or 5 A nominal current by parameterisation
Four-quadrant measurement (+P, -P, Q1 to Q4), apparent energy, 50/60 Hz and 16 2/3 Hz variants
Measurement system five times faster than industrial meters, accurate from 2% load in single-phase operation
Ethernet communication module fitted for DLMS/COSEM over TCP/IP; RS485 with DLMS and IEC 62056-21 optical port integrated
Three independent communication channels for different users (utility, generator, customer)
Load profiles with two independent profiles of 8 / 16 / 36 channels, 8 MB memory, 24 tariff energy registers and 41 diagnostic registers
Power quality: voltage and current monitoring, unbalance, over/under-voltage, voltage dip table, THD and harmonics, CT/VT error correction and line-loss compensation options
Up to 8 transmitting contacts (r4a: energy pulses, load supervision, capture periods) and tariff control
f9 rack-mount metal housing with Essailec connector for direct plug-in to socket sets in 19-inch racks and panels
Exchangeable communication modules: RS232, RS485, Ethernet, GSM/GPRS/UMTS
