Voltage divider Entube TE series

three-phase

Features Up to ±1500V input range on each terminal (line-to-line and line-to-ground) ±0.2V to ±10V output range (differential plus common mode) DC to 50kHz frequency spectrum of operation No power supply needed 4000V withstanding surge voltage for 5 seconds Designed for interfacing with differential input DAQs Details The Entube-TE series is designed for high quality three-phase measurements in a very compact form factor without need for power supplies. This series covers the ranges from ±50V to ±1500V, with up to 85kHz bandwidth and 0.2% accuracy. The Entube-TE sensor operates as a differential divider network with an anti-aliasing filter on its output. It generates a ±5V or ±10V scaled down version of the line-to-line and line-to-ground voltage on its input terminals. Depending on the software configuration, the sensor output phase-to-phase voltages for Delta configuration, or phase-to-ground for Wye configurations. This signal can then be processed by most computer based measurement platforms. One Entube-TE replaces 3 sensors, and only requires one cable for all three signals. This allows for very high channel densities, while delivering high performance for a low cost.
