Serie S604 / S711 MULTIFUNCTION POWER METERS (STANDARD AND COMPACT VERSIONS) S604 and S711 Series are instruments for the measurement and storage of electrical parameters. They are particularly suitable when a device for analysis and control is required consumption, with an excellent price/performance ratio. Rogowski current transducers versions offer extreme ease of connection and can be used in applications with high currents, linear measurements, retrofitting, energy audits etc. On request, the tools can communicate through the RS485 serial port with ModBUS RtU/ASCII protocol or via...

ROGOWSKI COILS ROGOWSKI COILS An air-cored toroidal winding is placed around the conductor, the magnetic field produced by the current induces in the coil a voltage proportional to the rate of change of current. Integrating this voltage the output become proportional to the current (as for a current transformer). Coil length variates from 25 to 300 cm for a cord diameter up to 8 mm • The junction point is insensitive to both the position of the internal conductor and to currents carried by external conductors • Coil and cable shielded against electromagnetic noise • Cross section reduced up...

HIGH PERFORMANCE ROGOWSKI COILS Rogowski coils have been used for the detection and measurement of electric currents for decades. They are based on a simple principle where an “air-cored” coil is placed around the conductor in a toroidal fashion and the magnetic field produced by the current induces a voltage in the coil. The voltage output is proportional to the rate of change of current. This voltage is integrated, thus producing an output proportional to the current. By using precision winding techniques, especially developed for the purpose, the coils are manufactured so that their...

ENERGY COUNTERS - S500 SERIES S500 Series ENERGY COUNTERS The new SENECA energy counters for DIN rail mounting cover the most different application requirements for single-phase and threephase systems. Available with RS485 Modbus, M-BUS or Ethernet + webserver communication interfaces, the energy counters are compliant with MID (2004/22 / EC Directive) in class B with EN 50470 standard. Equipped with Wide backlighted LCD display for easy consultation of the values of energy and power, the counters also make avalilable the diagnostic function signaling polarity errors in the connection....
