Magnetic Coreless Current Sensor "Currentier"

A low-heat current sensor that contributes to the miniaturization of substrates!

"Currentier" is a magnetic coreless current sensor IC equipped with a high-sensitivity Hall element. Despite being a coreless type, it achieves high precision comparable to that of closed-loop systems. Compared to conventional shunt methods, it has the following advantages: 1. The resistance value of the primary conductor is low at 0.27mΩ (which helps suppress heat generation), 2. The primary side does not require a power supply, allowing for a significant reduction in board size. Additionally, by offering a wide range of current options in the same package across the series, it enables the standardization of components and boards. 【Features】 - Capable of continuous high current operation (50/60/100A) - Creepage/clearance distance: ≧8mm (in compliance with UL61800-5-1) - Safety standards: UL1577 and IEC/UL62368-1 certified - Overall accuracy: ±0.4% F.S. (Ta=0~90℃ Typ.) *CZ370x series - Response time: 1μs Typ. *CZ370x series - Built-in disturbance magnetic field suppression function *For more details, please refer to the PDF documentation or feel free to contact us.

High current compatible compact/thin current sensor "CZ370x series"

Realizing the miniaturization of EV charging stations and the increase in output capacity! Coreless current sensor capable of detecting ±180A with surface mounting.

The CZ370x is a magnetic coreless current sensor that incorporates Hall elements. Due to the use of high-sensitivity Hall elements, it can measure a wide range of currents that typical coreless current sensors cannot achieve. It can handle continuous currents of up to 60Arms and accurately detect currents up to ±180A. 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 and allows placement in limited space on the circuit board. * It generates only 1/4 the heat of a shunt resistor (based on our comparative test data). ■ Reduction of manufacturing costs It can contribute 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.

A large-capacity AC current sensor that can be considered from a single circuit for a small start.

First, we will confirm compatibility and communication from one circuit. We will start small and support the gradual expansion of power monitoring to match operational needs.

When starting to monitor large-capacity circuits, many people think, "I want to confirm if the sensors are compatible with the target equipment" or "I want to test if the communication can be stable." With the PAL-Plus large-capacity version, you can conduct evaluation from a single circuit or a small number of circuits before full-scale implementation, gradually expanding the monitoring range while confirming operational results. The PAL-Plus large-capacity version offers four types: 125A, 250A, 400A, and 630A. You can select the optimal sensor according to the target current and cable diameter. Additionally, it adopts a split clamp type that is easy to install on existing equipment and supports data collection via Modbus RTU (RS-485) communication. This allows for future expansion into remote monitoring systems. 【Challenges】 - Want to confirm compatibility/communication before full-scale implementation - Want to reduce initial costs - Want to prepare for future expansion 【Expected Benefits】 - Optimal selection from four types - Easy to retrofit with a split type - Potential for future remote monitoring expansion For more details, please check the materials or feel free to contact us.
