DC CURRENT SENSOR DC VOLTAGE SENSOR J&D AC/DC CTs provide non-contact detection of AC/DC current. The AC/DC CTs have two types of split-core & solid-core design with various utility, high reliability & cost-effective solution for precise current measurements. The rated current range is 5A to 6000A AC/DC and secondary output value is 4/5/10V/333mV DC & 4-20mA, Instantaneous AC/DC current. 1) Measuring Principle of Open-Loop Current Technology Open-loop Hall effect technology creates magnetic flux from the input primary current and its magnetic flux couples a proportional low voltage, which amplify before being output. 2) Measuring Principle of Closed-Loop Current Technology The secondary current is generated by transferring the proportional voltage of the Hall Sensor originated by the magnetic flux from the primary current. The feedback of the compensating current via the secondary winding closes the loop, where by this current is an exact representation of the primary current. J&D AC/DC VT offers a comprehensive range of accurate, reliable and galvanically isolated devices to measure AC/DC voltage from 10V to 3000V across a range of technologies. 1) Measuring Principle of Closed-Loop Voltage Technology When a primary voltage is applied to the input resistor Ri, the current Ip flows through the wire of the input W1 coil and generates a magnetic flux passing the Hall Sensor. The closed-loop feedback amplifier used the Hall Voltage to generate a compensating current which is applied to the secondary winding W2 thereby creating the compensating magnetizing flux. This current is exactly proportional to primary current Ip through Ri and the input voltage Vm and as it flows through the output metering resistor RL, it creates a voltage drop Vm which equals the input voltage it Ri=R2. 2) Measuring Principle of Isolation Amplifier Technology Our Isolation Amplifier Technology Voltage Sensors – iSAST EVS series begins with and internal resistor network. This network measures DC voltage by directly contacting both the Positive High Voltage (+HT) and the Negative High Voltage (-HT). This voltage signal is transmitted to the secondary side of the sensor through an insulated transformer that isolates the primary high voltage from the secondary low voltage. The resulting signal is then converted through an amplifier into either a current of a voltage signal. Therefore the circuit converts a primary voltage into a secondary current or voltage that is proportional to the input. DC CURRENT SENSOR / DC VOLTAGE SENSOR
