What is the output of ACS712?
Application 1. The ACS712 outputs an analog signal, VOUT . that varies linearly with the uni- or bi-directional AC or DC primary sensed current, IP , within the range specified.
What is the supply voltage of ACS712?
5V
The ACS712 is a 5V device, and must be connected to the VU pin on the MBED. The 5 amp version of the ACS712 has an output range of 1.5-3.4 volts….Usage.
| ACS712 Breakout | MBED | Circuit under test |
|---|---|---|
| Vout | Analog pin (p18) | |
| FILT | 1nF capacitor to ground | |
| GND | GND | |
| + Loop | Positive side of wire |
Is ACS712 bidirectional?
Newer chips like the ACS724 current sensor chip do offer some DC versions but the ACS712 can be used in both bi-directional and uni-directional applications.
Can I measure DC current with a clamp meter?
AC/DC current: Current, measured in amperes, is the flow of an electric charge and is the most basic measurement of a clamp meter. Most modern clamp meters can measure both AC and DC current.
What is the working principle of ACS712 current sensor?
The ACS712 is designed to three ranges of current 5A,20A and 30A, the sensor consist of integrated circuit that works according to Hall-Effect principle it generates voltage proportion with the flowing current in the electric device[10].
Can an AC amp clamp measure DC amps?
Hall Effect clamp meters can measure both ac and dc current up to the kilohertz (1000 Hz) range. Like current transformer types, Hall Effect clamp meters use rigid iron jaws to concentrate the magnetic field that encircles the conductor being measured. This gap limits the magnetic flux so that the core cannot saturate.
What does the ratiometric feature of the acs712 mean?
The ACS712 and ACS713 use Hall effect technology, which is compatible with electrical currents having both DC and AC components. The bandwidths are 80 kHz typical. What does “ratiometric” mean? The ratiometric feature of the ACS712 and ACS713 means the device gain and offsets are proportional to the supply voltage, VCC.
What’s the difference between AC and DC currents?
In direct current (DC), the electric charge (current) only flows in one direction. Electric charge in alternating current (AC), on the other hand, changes direction periodically. The voltage in AC circuits also periodically reverses because the current changes direction.
What’s the maximum temperature the acs712 can withstand?
Steady state thermal testing with continuous DC (or AC RMS) current, based on Allegros ASEK712 demo board, shows that at an ambient temperature of 85°C the ACS712 can withstand a maximum of 40 A before reaching the maximum thermal junction temperature of 165°C.
