Alvi Technologies launches the new series of galvanic isolators: ProLine 50000 -suits the demands for railway applications.

Transducers of the new ProLine P50000 series are specially developed for voltage and current measurement in main and auxiliary power circuits of locomotives and multiple units. They are used, for example, for short circuit detection as well as for monitoring of traction motors and inverters, auxiliary inverters and accumulator batteries. The devices comply with all applicable railway standards and thus meet the high demands of fire protection (HL3 according to EN 45545-2 (2016)), electrical safety, mechanical robustness as well as insensitivity to extreme environmental conditions and electromagnetic interferences.

Compared to conventional sensors used in railway vehicles, ProLine P50000 transducers stand out due to their calibrated range selection feature and integrated universal power supply unit. Calibrated range selection allows different input ranges up to ±4200 V to be selected quickly and flexibly. After the switchover, the specified high accuracy (< 0.1 per cent meas.val. + 0.1 per cent f.s.) is maintained without readjustment. Combined with a shunt resistor, the device is suitable for precise current measurement up to the kA range.
