Grove - 2.5A DC Current Sensor 直流電流傳感器 (ACS70331) (101020652)
DESCRIPTION
The Grove - 2.5A DC Current Sensor(ACS70331) is a high precision DC current sensor based on ACS70331. The ACS70331EESATR-2P5U3 is Allegro’s high sensitivity,current sensor IC for <2.5 A current sensing applications. It incorporates giant magneto-resistive (GMR) technology that is 25 times more sensitive than traditional Hall-effect sensors to sense the magnetic field generated by the current flowing through the low resistance, integrated primary conductor.
The Grove - 2.5A DC Current Sensor(ACS70331) can measure the DC current up to 2.5A and has a base sensitivity of 800mV/A. This sensor do not support AC current, if you want to measure the AC load please check the:
Grove - ±5A DC/AC Current Sensor (ACS70331)
Danger
The human body is forbidden to touch the module during the test, otherwise there is danger of electric shock.
危險
試驗期間禁止人體接觸模塊,否則有觸電危險。
FEATURES
- 1 MHz bandwidth with response time <550 ns
- Low noise: 8 mA(rms) at 1 MHz
- 1.1 mΩ primary conductor resistance results in low power loss
- High DC PSRR enables use with low accuracy power supplies or batteries (3 to 4.5 V operation)
