Current Sensor Related: S22P Series

Current Sensor Related: S22P Series

This is the "S22P" series of current sensor-related products. They can be used in UPS systems, inverters, motor control, welding machines, and more!

<Rohs Directive Compliant> The "S22P" series of current sensor-related products can be utilized in UPS systems, inverters, motor controls, welding machines, and more! It features a low-cost M2: enhanced type for resistance to external magnetic field noise (model: S22P***S05M2), and is a magnetic balance type / voltage output type. The mounting structure is on-board, the primary conductor is built into a busbar, the rated current is 6-25A, and the power supply voltage is ±5V. The Hall current detector measures current non-contact by combining a magnetic core and a magnetic sensor (Hall element) that generates magnetic flux proportional to the current, eliminating voltage drop for measurement, providing excellent insulation, and allowing measurement of alternating current, direct current, and mixed currents, making it an ideal device. The magnetic flux generated proportional to the current If is concentrated by the iron core and passes through the Hall element inserted in the gap, outputting a voltage according to the Hall effect described by the formula Vh = k ・ Ic ・ B. For more details, please contact us or download the catalog.
