[Current Sensor Related] S21S Series
This is the "S21S" series of current sensor-related products. They can be used in inverters, motor control, UPS, and welding machines!
<Rohs Directive Compliant Products> The "S21S" series of current sensor-related products can be used in inverters, motor control, UPS, and welding machines. They feature a low-cost magnetic balance type/current output type, with a mounting structure that includes connectors, a primary conductor that is through-type, a rated current of 180A, and a power supply voltage of ±15V. 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, resulting in no voltage drop for measurement, excellent insulation, and the ability to measure 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.

High current compatible compact/thin current sensor "CZ375x series"
Achieving miniaturization of EV charging stations and increasing output capacity! Coreless current sensor capable of detecting ±225A with surface mount.
The CZ375x is a magnetic coreless current sensor that incorporates Hall elements. By using high-sensitivity Hall elements, it can accurately measure a wide current range of ±115A to ±225A, which is difficult to achieve with typical coreless current sensors. Continuous current flow is also possible up to 100Arms. Therefore, it contributes to "increased output capacity." Additionally, compared to shunt resistors and core-type through-hole sensors, it can contribute to "miniaturization" and "reduction of manufacturing costs." ■ Miniaturization - Due to its small size and surface-mount package, it can be mounted on the back side of the circuit board. - The primary conductor has low resistance (0.27mΩ), which suppresses heat generation, allowing it to be placed in limited space on the circuit board. * It generates one-third the heat of other companies' coreless current sensors (based on our comparative test data). ■ Reduction of manufacturing costs It contributes to reduced manufacturing (assembly) costs by eliminating the need for wire connections to through holes. * For more details, please refer to the PDF document or feel free to contact us.

High-speed response compact/thin current sensor "CZ3Axx series"
Contributing to the improvement of system safety! Coreless current sensor with built-in high-speed, high-precision overcurrent detection function.
CZ3Axx is a magnetic coreless current sensor with built-in Hall elements and overcurrent detection functionality. It achieves a high-speed response of 1μs and high precision of 0.3% F.S., enabling the detection of various fault modes such as ground faults and arm short circuits, contributing to improved system safety. Additionally, through its unique packaging technology, it realizes a low primary conductor resistance of "0.27mΩ" and high insulation with a creepage/clearance distance of ≧8mm. This significantly reduces heat generation during current application compared to shunt resistors, and eliminates the need for a primary side power supply or amplifier for insulation, allowing overcurrent detection with just the IC. Therefore, it can be placed in limited spaces on a circuit board. *For more details, please refer to the PDF document or feel free to contact us.
