TWM is a digital wattmeter for measuring and recording on three-phase power lines arranged into a 9 mod. DIN 43880 rail mounting enclosure. Equipped with display, serial interface and non volatile memory for data storage, TWM is expressly apposite for energy monitoring and consumption reporting. All the operating parameters and recorded data can be accessed via serial interface using the software Elite (or a Modbus master unit). The Elite software allows a complete management of a TWM network togheter with DAP and DAPLite peripherals, making a really powerful loads and consuption monitoring systems, for LV/MV/HV users. TWM main features are the following: - True RMS measure - 4 quadrants (bidirectional) measurements - 3 Voltage channels with common neutral - 3 Insulated current channels with CT (.../5A) - 2 digital inputs and outputs - LCD display backlighted, 2 x 16 digits with page scroll button - RS232/RS485 serial interface - 128/512 kB non volatile memory for measurements storage - Real-time clock calendar with back-up - Rail DIN 46277 (EN50022) fastening Available versions Product codes: EMsss-mmm-vvv-c where: - sss: serial interface 232=RS232; 485=RS485 - mmm: memory size 128=128k; 512=512k - vvv: voltage range 100=100V; 400=400V - c: channel range 1=1A; 5=5A
