Max471 Voltage Current Sensor Voltage Load Detection

Description

• Max471 Voltage Current Sensor Voltage Load Detection
• Test Voltage range: DC3 – 25V (Arduino work on 5V) or DC3 – 16.5V (for Arduino work on 3.3V)
• Test Current range: DC 0 – 3A, Precision 2%, current and voltage transformation ratio is 1V/A

Detection Pin Description:

• Max471 Voltage Current Sensor Voltage Load Detection
• VT: voltage detection pin, the detection voltage is 1/5 of the input voltage.
• AT: current detection pin
• GND: Connect to  the Arduino GND
• VOUT/VIN: VOUT=VIN

This module can be used to test the current and voltage in the circuit.

The principle of voltage test based on the principle of resistive voltage divider design can make the red terminal connector input voltage 5 times smaller. for Arduino analogue input voltages up to 5 v, the voltage detection module input voltage not greater than 5V x 5 = 25V (if using 3.3V systems, input voltage not greater than 3.3V x 5 = 16.5V).

Package included: 1x Max471 Voltage Current Sensor Voltage Load Detection
