Overview
The MG
series device is a high performance current sensor based on Magtron ASIC Quadracore
technology with high accuracy in the full temperature range, adjustable analog
output.
It’s suitable for the application of industrial products, such as the inverter,
UPS, servo motor driver and other industrial products. The ultra-small package
is designed for the high power density application and easy to use.
MG
series is designed for the replacement of shunt solution and the transformer
solution with high cost effective.
Application circuit
Note:
C1, C2 should be close to the current sensor’s pin
