NOYITO MAX471 Current Sensor Module Current Detection Current Measurement Module 0-3A Range
NOYITO MAX471 Current Sensor Module Current Detection Current Measurement Module 0-3A Range
Note: The users of this product need to have high professional ability, novices are recommended to use it under the guidance of professionals. Description: This module uses the high-precision current detection amplifier chip MAX471.The module does not require an external power supply. The module directly uses the detected power supply to supply power. It is generally used in the current detection of circuits with a working power supply of DC3-36V. The module contains a precision detection resistor, and the detection capability is 0-3A. When used in parallel, the ability to detect current can also be improved. The output terminal is a voltage value proportional to the current (1V/1A: that is , the output voltage value is 1V, which means that the detected current value is 1A, 1.5V/1.5A, 2V /2A...). Parameters: Working Voltage : DC3-36V. Maximum Supply Current: 100uA. Detection current range: 0-3A. Current-voltage conversion ratio: 1V / A. The normal operating temperature range, accuracy: 2%. Dimensions: 24.3mm 17mm. Wiring instructions Input wiring: INPUT+: Connects to the positive of the power supply (positive side of the load power supply), IUPUT-: Connect to the positive of load . GND: Connect to the negative terminal of the power supply or load. Output wiring: The OUT output is a voltage value that can be connected to the AD input of the microcontroller. The ratio of the output voltage value to the detected current value is 1V/A. (ie, the output voltage is 1V, which means that the detected current is 1A) GND is connected to the negative pole of the microcontroller. Package Included: NOYITO 1pcs MAX471 Current Sensor Module
