Transcription

1 GENERAL Electrical multifunction analysers On top of the previously mentioned instruments, Contrel Elettronica offers also a complete range of electrical parameters analysers EMA series, for monitoring, measuring, registering, analysing and managing of all parameters of the energy distribution networks, with advanced functions, which grant its practical and simple use. Their main features are detailed here below Extremely high performances with an outstanding price / quality relation. Convenient application, as a simple multifunction meter in electrical boards even. General informations, relative to the instrument, to its firmware version, serial number, configuration inputs and outputs, options, communication protocol, etc. Rms values and high accuracy of all electrical parameters, with a 0.5 class for voltage and current, so as class 1 for energy meters, according with IEC 1036 Measure of the neutral currents Reading of the Total Harmonic Distortion (THD) of current and voltage for each individual phase Measure and management of measured values, average, maximum and minimum (relative to a period and absolute) of the various measures, for a complete and precise analysis of the distribution network. Analysis of the harmonic components for voltage and current, up to the 31st in order, with 50 Hz. Active and reactive de energy bidirectional energy counters, for the energetic balance or ( absorbed co-generation) Energy meters, subdivided in 4 time bands of 10 periods programmable for a complete management of the energetic costs. Visualisation of the voltage and current wave forms Possibility of field measuring by memorising, in time, of the values, average, maximum and minimum and harmonic components. Built-in clock calendar They verify the appropriate wiring of the instrument (external CT s wiring for the current inputs and phase sequence for the voltage inputs) 5 14

2 Electrical multifunction Analysers Management of optional parameters, non electrical even, of the additional inputs, becoming a complete acquisition measures unit. Internal memory of 128Kb, which up to 1Mb, for registering purpose. Simple and intuitive programming and use, with a friendly menu, which allows an easy visualisation of the scrolling pages. Verifying the internal memory status, used and available of the registers. Complete programming of the working parameters (setup, transformation ratios CT s and Vt s, average times, alarms, hysteresis, peripherical connections, printing, etc.) Fully programmable alarm outputs, with selection of parameters, time delay, hysteresis of maximum/ minimums etc. Digital inputs (up to 8) for pulse counting, synchronisation, time bands definition, connection to external meters etc. Digital outputs (up to 6) for alarms signalling (of max/min with time delay, hysteresis, etc..) and loads operation or programmable energy pulse re-emission. Output/input contacts situation, in order to check the situation of the various operations and drives. Programmable communication protocol or Modbus -RTU Registering and graphic visualising of the measures, with the possibility of local printing. Possibility of functions updating, by connecting through the serial port, which allows successive upgrading without substituting the instrument. Friendly software NRG for Windows environment, for the instruments management from a PC (up to 128 nodes network) through a serial line. RS 485/ RS 232 selectable serial output Additional serial outputs for connecting a local printer or connecting to a modem for remote data transmission. Analog outputs (up to mA, 4 20mA, etc.) fully programmable and bi-directional to be associated to whatever parameter. Programmable synchronisation mode of the instrument. Internal compensated temperature sensor. Reliable and robust supply terminals 19 60Vac/dc or Vac/dc Optional plug-in modules, for memory expansion, number of digital/analog inputs and or outputs, additional serial output, without substitution of the instrument. Various local visualisation modes of the parameters (by means of the graphic back lighted LCD displays of high resolution, in various dimensions or by means of a back lighted alphanumeric LCD display or by means big dimensions alphanumeric red LED display. DIN 96x96mm or DIN 144x144mm enclosures for flush mounting onto a panel or for DIN rail mounting 9 modules. Great front protection degree (IP55) and reduced depth (60mm for EMA14/14H - EMA10/10H - EMA11/11H versions) Practical screw draw out terminals with safety latching. 15
