External wiring diagram

Instructions for Use

1. When measuring voltage, the Ri resistor is connected in series on the primary circuit of the sensor. To achieve optimal accuracy of the sensor, the size of Ri should be selected as much as possible to make the input current around 10mA.
2. Scope of work: Considering the internal resistance of the primary coil (compared to Ri, to maintain the temperature difference as low as possible) and isolation, this sensor is suitable for measuring voltages ranging from 10 to 500V. To ensure the stability of measuring resistance, the power of Ri should be at least 4 times the rated power (usually above 10W). 3. When soldering the sensor to the circuit board, a low-temperature soldering iron should be used, and the soldering time should be as short as possible, otherwise it may cause an open circuit in the internal wiring of the pins.
4. The socket position for installing sensors on the circuit board must be completely consistent with the pin size, and the pins should not be artificially squeezed, otherwise it may cause open circuits in the internal wiring of the pins.
