WCS2702 AC/DC 전류 센서 -UART
(WCS2702 AC/DC Current Sensor -UART)
개요
- 본 제품은 WCS2702 AC/DC 전류 센서 -UART입니다.
- AC/DC 전류를 측정이 가능하며, UART 인터페이스를 통해 센서에 명령을 주고 받을 수 있습니다.
- 포텐셔미터를 이용하여 threshold 알람 값을 설정이 가능하며, UART 명령을 통해도 threshold값의 설정이 가능합니다.
특징
-
1>.UART directly read the dual axis horizontal value2>.The on-board potentiometer can adjust the threshold and control the relay in comparison with the analog voltage.3>.It can set alarm value4>.Adapt to MCU and PC5>.Support AC and DC current test

- .In the test process,if you need to switch from DC test to AC test,or switch from AC test to DC test,you only need to calibrate and retest.It can be used for motor over-current detection,short-circuit protection detection,over-current protection,demonstration teaching experiments,different load detection and so on.
