Welcome Here  Shenzhen Mingjiada Electronics Co., Ltd.

The Allegro ACS37612LLUATR-015B5 current sensor IC provides a low cost solution for AC and DC current sensing without the need for external field concentrator cores or shielding. It is designed for applications where hundreds of amperes of current flow through a bus bar or PCB.

The current flowing through the busbar or PCB line generates a magnetic field which is sensed by a single, low offset, linear Hall IC. The differential sensing topology virtually eliminates all types of errors due to common mode stray magnetic fields. High isolation is achieved through the contactless nature of this simple component.

• 1.Is the inventory and price seen on the platform accurate?

  A: all online goods on the shelves can be ordered online, but considering the large liquidity of spot inventory, it is not possible to achieve 100% accuracy at present. In case of any abnormality, you can contact our company online and give the corresponding solution.

• 2.Are all our products genuine?

  A: our self-supporting products are from cooperative domestic and foreign original factories or authorized agents, and the source can be traced to ensure the original and authentic products.

• 3.Can you provide the qualification certificate of the original factory or agent?

  A: at present, our self-employed brands TI，ST，ADI，NXP，LATTICE，CYPRESS，INFINEON，XILINX and other first-line brands. Other channels are the original factory and agency channels. If necessary, we can communicate and confirm according to the specific brand and model.

• 4.Can I make an inquiry through the company's website?

  A: You can inquire through the website, or by phone and email.

• 5.When can I deliver the goods after placing an order? How long will it take to get there?

  A: the delivery date is marked in most commodity information. You can estimate the delivery time of the commodity according to the delivery date. The specific arrival time depends on the warehouse where the commodity is located and the logistics mode you choose.

• 6.Can the company issue an invoice?

  A: you can issue ordinary invoices for individual users or special VAT invoices for enterprise users.
