Czujnik prądu ACS714 Specification

  • Supply voltages of the logic part: 4.5 V to 5.5 V
  • Current consumption of the logical part: 13 mA
  • Sensitivity for power supply of 5V: 0,185 V/A
  • Weight of the module of 1.3 g
  • Dimensions: 18 x 20.5 mm

 

Description

The module consists of a printed circuit board made for the system Allegro ACS714LLCTR-05B-T. The sensor operates based on the Hall effect. The chip can be powered from a voltage in the range: 4.5 V to 5.5 V.

 

Basic module features:

  • The system is designed for current flowing in both directions (from -5A to 5A)
  • Due to the low resistance of the system (1.2 mΩ) and channeling, the power losses are very small.
  • Through the use of Hall effect, the current paths are isolated from the logic part.
  • The bandwidth is up to 80 kHz with the possibility of reduction by adding an additional condenser
  • Precision of 1.5% at room temperature.

 

Connection method

The sensor requires a supply voltage in the range from 4.5 V to 5 V, connected to the pins designated as VCC (+) and GND (ground). The output is a voltage signal proportional to the intensity of the measured current. When the voltage VCC is equal to 5 V, the output is centered on the half, that is 2.5 V. The output value increases by 185 mV at 1 A when the strength of the measured current is positive, otherwise, it decreases.

Additional filtering

The chip has an internal resistance filter of 1.7 , the board has the condenser with the value of 1nF, which together form a low pass filter with cut-off frequency of 90 kHz. The user can change the filter when the capacitor is output onis called "filter". The limit frequency can be calculated by the formula:

 

F = 1 / (2πRC) = 1 / (11kΩ * (1 nF + Cf))

 

where Cf is the capacitance of the capacitor soldered into the "filter" pins.
