Documentation
The Entube-QE series is designed for high quality three-phase measurements plus neutral 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-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 voltage on its input terminals.
This signal can then be processed by most computer based measurement platforms.
One Entube-QE replaces 4 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.
