Class 0,5S Energy Analyzers The Exa series are microprocessor-based energy meters / analyzers suitable for harsh environments. Equipped with an RS485 Modbus RTU port. Indication of the phase sequence, four operating time counters in addition to more than one hundred measurements. Versions with digital and analogue inputs - outputs. Perform the functions of analyzer, counter and multimeter. True-RMS and accurate measurements Measurements in true effective value (True-RMS), obtained by continuously sampling the waveforms of voltages and currents, and the automatic offset compensation of the internal amplifiers ensure maximum precision regardless of the variability of loads over time (ex. spot welders), from the signal level and the environmental operating conditions. The 64-bit resolution also ensures a high accuracy of the energy measurement even in the presence of small loads (e.g. equipment in stand-by). Measures Simple to use Exa D6, 96 and Exa MID are equipped with an LCD graphic display (dot matrix) with LED backlighting and 2 levels of contrast. Simultaneous reading of 4 parameters and of their symbols with high visibility mode. Energy oricsyzer The 6-key Joystick keypad (in line for the Exa 96) and the menu column on the display for configuring provide a simple and rational instrument use. In addition the initial page displayed when the instrument is turned on can be defined by the user. On the front panel two red LEDs, for calibration checking, pulse with a frequency proportional to the active and reactive energy imported. Under the sine wave symbol next to the Electrex logo a red LED indicates the operation status, while 2 other LEDs (one red and one green) below the white band indicate the communication activities of the RS485 port. All Exa (except Exa MID) are equipped with RS485 port and suitable for use on any type of grid, 3 or 4 wire, symmetrical or asymmetrical, balanced or unbalanced, two-phase, singlephase, low and medium voltage, with 1, 2 or 3 CTs as well as for measurements on 2/4 quadrant (import / export). A keyboard programming allows you to set all operating parameters such as RS485 port, network type, LV / MV, CT and eventual VT ratio (free setting), integration time (1-60 min.) and depending on the version: analog outputs, digital outputs, relay and alarm outputs (thresholds, delay and hysteresis), analog and digital inputs. The programming system is password protected against unwanted changes. Exa MID is instead suitable for insertions in three-phase 3 and 4 wires, low voltage systems and only with ../5A CTs. All the Instantaneous measurements are calculated on 10 cycles, for e.g. 200mS at 50Hz (1) Average values on Integration time (1 .. 60 mIn programmable) and peak (MD). (2) Average values (moving average) both In Import and In Export on the Integration time (1..60 mIn programmable) and peaks (MD) or the maxImum average value. (3) Maximum power values In both Import and Export. (4) Non-resettable life time and four partial operating time counters. (5) The energIes (whIch consIder the CT ratIo) In both Import and Export are dIsplayed as 9 digits (one decimal). The Internal counters are stored In 64-bit resolution which ensures a minimum definition of 0.1 Wh and a maximum count of 100 GWh. (6) Only for versions with digital Inputs. (7) For MID models the frequency Is between 45 Hz and 55 Hz. The energy counters at the terminals level (total and each phase) in both Import and Export are non-resettable (MID) and resettable partial total counters are displayed at 9 digits (one decimal); internal counters are logged as In point (5). (8) Three partial counters for each measurement marked Electrex is a brand of Akse srl Via Aldo Moro, 39 42124 Reggio Emilia Italy Tel. +39 0522 924 244 Email: [email protected] Web: www.electrex.it BimmnHm the energy saving technology Engineered and manufactured in Italy Pensato, progettato e prodotto in Italia

Indication of the phases sequence When the display is set to display the three phase voltages and the frequency, the indication of the phases sequence is also displayed, for example L123. Serial port communication The Exa are equipped, as a standard feature in all types, with an RS485 serial port with overvoltage protection. The communication protocol used is the “full compliant” ModbusRTU suitable for communications with PLC and SCADA programs. The processed data are read as numeric registers composed of mantissa and exponent in IEEE format. A transmission up to 38.400bps with max. 125 registers...
