1、 Introduction
The WCS1800 Hall current sensor has two main functions. The first function is to follow the analog signal through the operational amplifier, which is suitable for A/D conversion; The second function is the switch signal, which can pre-set the current limit value. When the actual current value is greater than the pre-set current value, the switch signal will change from low level to high level and have an LED indicator light to indicate. Easy to use.
2、 Module parameters
Working voltage: DC5V
Current detection range: DC: ± 35A, AC: 25A (applicable to analog output);
Linearity: K=60mV/A;
Current limiting range: 0.5A-35A (applicable to switch output);
Sample current conversion to analog voltage signal output, can be connected to ADC, TTL level signal output, can be connected to microcontroller IO port control.
Output signal: analog voltage signal and switch signal indicator light: with overcurrent indicator light
Sealing material: epoxy resin
Module power supply voltage: 5-30VDC
