CHVS5/25A Hall sensor module closed-loop voltage (current) sensor
CHVS5/25A Hall sensor module closed-loop voltage (current) sensor
Product details
CHVS025AThe series sensor is a Hall voltage (current) sensor based on the closed-loop magnetic balance principle.Capable of directly measuring DC, AC, pulse, and various irregular currents. The preferred solution for voltage measurement has excellent cost-effectiveness and can also be used formAMeasurement of small current levels.

instructions:
Resistance R1 ensures optimal accuracy of the sensor when the input current is at the rated primary current, therefore the sensor should measure the voltage corresponding to a primary current of 10mA as much as possible.
For example, measuring voltage VIN=250V
Accuracy=± 0.8% ofVIN (@ Ta=+25 ℃) a) R1=25K Ω/10W, IP=10mA
Accuracy=± 1.6% of VIN (@ Ta=+25 ℃) b) R1=50K Ω/5W, IP=5mA
The operating range (recommended) takes into account the resistance of the primary coil (which may be lower compared to R1 to maintain a close temperature difference) and isolation, making this sensor suitable for measuring voltage.
Main tolerances
- Total tolerance ± 0.2mm
- Pin 2 for connecting the primary coil, 0.8mm * 0.8mm
- Pin 3 for connecting secondary coil 0.8mm * 0.8mm
