TBV5/25A,10/25A series voltage sensor is a closed loop device galvanic isolation between primary and secondary circuit, it can measure DC, AC and pulse voltage. This series voltage sensor has rated current input in 5mA and 10mA, meausre upto 14mA. Considering resistance of primary coil and electrical isolation within measure range, this sensor is suitable for measuring voltage. It has 0.5% accuracy, very small, very reliable. Available for appearance customization.

2. General tolerance ±1mm
Directions for use |
1. The accuracy of sensor will be the best when the current passes through resister R1 and becomes the rated primary current, and therefore the current to be measured by sensor should comply with the primary current 10mA.
2. For example, VIN=250V:
(Accuracy )=±0.8%ofVIN(@Ta=+25℃) a) R1=25KΩ/10W,IP =10mA
(Accuracy )=±1.6%ofVIN(@Ta=+25℃) b) R1=50KΩ/ 5W,IP =5mA
3. Considering resistance of primary coil (compared with R1 and temperature difference kept as low as possible) and electrical isolation within measure range (recommended), this sensor is suitable for measuring voltage.
