Welcome Here  Shenzhen Mingjiada Electronics Co., Ltd.

ADE7757ARNZRL is an integrated circuit for accurate energy metering. It is a variant version of the ADE7755 with fewer pins than the latter, but with the addition of a precision oscillator circuit that serves as a clock source for the chip. Since no external crystal oscillator or resonator is required, the total cost of the meter with ADE7757A is reduced. The chip can be directly interfaced with the shunt resistor.

Features

Exceed IEC62053-21 standard requirements

The active energy error is less than 0.1% in the dynamic range of 500:1

Active energy metering

High frequency pulse output

Current sensor interface for current transformers or shunt

On-chip temperature sensor and reference voltage source (2.45V)

Low power consumption: 20 mW (typical)

Reverse Power Indication (REVP)

• 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.
