Rongtech Industry(ShangHai) Inc., RTV5、10/25A Series Hall Effect Voltage Sensor The RTV5、10/25A series current mode voltage sensor is a device based on the principle of the hall effect, with a galvanic isolation between primary and secondary circuit, It provides accurate electronic measurement of DC AC or pulsed currents. Electrical data(Ta=25℃±5℃) Type RTV5/25A RTV10/25A Unit Parameter Rated input (Ipn) 5 10 mA Measure range(Ip) Turns ratio(Np/Ns) Primary coil resister Secondary coil resister Measure resister Rated output (Isn) Power consumption Supply voltage Zero offset current Offset current drift Response time Linearity Galvanic isolation Applications 1.AC variable speed drives and servo motor drives 2.Static converters for DC motor drives 3.ariable speed drives 4.Power supplies for welding applications 5.Battery supplied applications 6.Uninterruptible Power Supplies (UPS) 7.Switched Mode Power Supplies(SMPS) Directions for use 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. 1. VIN=250V 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 2. Considering resistance of primary coil (compared with R1 and temperature difference kept as low as possible) and electrical isolation within measure range (recommended),
