ENTUBE DE (1000V 10V)

Entube DE Double Ended - Line to Line Voltage Sensor OVERVIEW The Entube-de series is a family of voltage transducers designed for high quality differential measurements in a very compact form factor, and without need for power supplies. This series covers the ranges of ±50V to ±1500V with up to 50kHz bandwidth and up to 0.2% of signal accuracy. The Entube-de sensor operates as a differential divider RC-network with an anti-aliasing filter on its output. It generates a ±5V or ±10V scaled down version of the difference between the two input voltages, which can then be processed by a computer based measurement system. The Entube-de is part of Verivolt’s sensing platform, which is aimed at allowing users to laid out multiple distributed sensors with a minimum of cabling required and no power supplies. This platform together with the Entube-de ultra-compact form factor, allows for very high channel densities, while delivering high performance for a low cost.

It outputs all line-to-line and line-to-ground signal pairs. Delta or Wye measurements can be made depending on the input configuration of the digitizer being used (NRSE or Differential). < 400 μV 150 > 3 MΩ 15kΩ 10kΩ Integrated sensor noise (Referenced to input) Accuracy (percentage of reading) ±0.2% (±0.05% Typical) Gain (Using 10V standard output voltage) Max total phase shift at 60Hz < 0.05° Common mode rejection ±2000V Withstanding differential mode surge voltage ±1000V Input-Output non-linearity Output voltage Gain temperature drift Mounting Type DIN Rail Connectivity In Clamp cage Connedtivity Out Spring cage < 250 ppm ±5V (±10V optional) ±50 ppm/°C Differential input dynamic range Signal Layout Common mode rejection 52 dB Power Supply Voltage None Output type Output Offset Voltage Mechanical Weight 400V 85kHz Integrated sensor noise (Referenced to input) Outer Dimensions 300V Double-ended signal < ± 10µV (on ±10V signal) Environmental Operating temperature – 25 to 70 °C Storage temperature – 40 to 80 °C The two input phases connect to the sensor via a Spring-cage, while the conditioned signals from the sensor come out on a standard screw terminals. The Entube DE can be mounted anywhere between the signal source and the data acquisition system. A female-screw on the low voltage side of the sensor allows for DIN rail mounting, and serves as a safety ground. A twisted pair should be used to carry the conditioned signals from the sensor. This will keep good resolution beyond the 10th harmonic on a typical 60Hz system. 1.4” x 1.4” x 4.5” 198 g (7.0 oz) 650 Washington St, San Francisco, CA 94111 70VERIVOLT (708) 374-8658 1 MERCHANICAL DIMENSIONS HARDWARE CONFIGURATION A.
