Entube QE Series

Three Phase Plus Neutral Voltage Sensor

Verivolt LLC

The Entube-QE series is designed for high quality three-phase plus Neutral measurements in a very compact form factor without need for power supplies. This series covers the ranges of ±100V, ±200V, ±300V, ±400V, ±500V, ±750V and ±1000V, with up to 85kHz bandwidth and 0.2% accuracy. The Entube-QE 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 or line-to-neutral voltage on its input terminals. Depending on the software configuration, the sensor outputs phase-to-phase voltages for Delta configuration, or phase-to-neutral for Wye configurations. This signal can then be processed by most computer based measurement platforms. One Entube-QE replaces 4 differential sensors, and only requires one cable for all four signals. This allows for very high channel densities, while delivering high performance for a low cost.
