WHAT'S IN THE BOX:

- Hall Effect Current Sensor

- Includes 12V wall transformer for orders inside the U.S., Canada, Mexico

- Includes power cord only for other countries

 

 

 

MODEL: H-ACDC-70   Up to ± 72 Amps DC or AC Current,   Output Sensitivity = ~33mV per Amp

MODEL: H-ACDC-125   Up to ± 125 Amps DC or AC Current,  Output Sensitivity = ~19mV per Amp

NOTE:  Looping your wire through the sensor multiple times will increase sensitivity

  • By default, this sensor puts out a 4 Volt DC signal.  For every Amp the sensor detects, this Voltage will change up or down depending on the direction of the current.   If you don't like having this 4 Volt default offset voltage, and you want to zero it out, then check out out the H5-ACDC-XX

  • 3µ second response time

  • Uses quality CSLA2CX series sensor made by Honeywell (datasheet here)

  • 2.5mm input power connector (polarity protected  with diode)

  • Includes 12V wall transformer for orders to U.S., Canada, & Mexico

  • Ships within 2 to 3 days inside U.S.,  2 to 3 weeks outside U.S. using Express Mail

  • Satisfaction Guaranteed

  • For AC or PWM - you're able to zero the offset by putting a capacitor on the output signal to your data logger or volt meter or O-scope

EXAMPLE DATA FROM SENSOR

Below you can see real data from just one  sensor for a solar panel / battery charging application. The green trend line represents data from the sensor.   The red trend line has been converted to Amps using  the following  linear equation.   Amps = ( Vsensor - 4.0) / ~32mV

 As the sun comes up, current slowly flows into the batteries rising from 4 Volts DC to 4.5V DC.  This corresponds to a current range of Zero amps up to 16 Amps shown in red on the right side of the graph.  

When someone in the home turns on an electric appliance then the current goes negative down to 2.6 Volts DC because it changes direction as it flows from the batteries into the House AC inverter which could be powering something like a refrigerator  or washing machine.  A value of 2.6 Volts DC output converts to a current value of ~ -45 Amps.  Assuming these batteries are setup in a 24 Volt configuration, then you could use this current measurement to approximate how much power your batteries are putting out.  In this case it would be about 1,080 Watt power output to the inverter.

(24V X 45A = 1080 Watts)

FAQ:
When measuring AC current, does this sensor put out an AC or DC signal.  
ANSWER:  It puts out an AC signal. 

 
If I am using this with a 24 Volt battery application can I just hook the operating power up to the battery? 
 ANSWER: Yes,  this device can take a 12 to 30 Volts DC power supply to excite the transducer using the black 2.5mm positive center.
 
What is the absolute maximum current this device can measure? 
ANSWER:  This board uses high quality CSLA2CX series transducers  made by Honeywell.   It has a max current range  specification of ±72 Amps or ±125 Amps depending which model you choose. 

 

How can use this sensor for low current situations less then one amp? 
ANSWER:  All you have to do is loop the wire through the sensor multiple times until you get the signal strength you need.  Then divide the measurement you are getting by how many loops you have put through the sensor.  For example, if you loop your current carrying wire through the sensor 10 times, and you get a measurement of 4.032 and your sensor measures 4.0 when no current is flowing through the transducer,  then the approximate current calculation would be :  
 
((4.032 - 4.0)/ 0.033) / 10 = 0.096 Amps or 96mA
 
 
How can I monitor current from a PWM (Pulse width modulation) signal? 
ANSWER:  There are two ways of doing this.  First is for you to get a data acquisition box that can sample at least 10 times the frequency of your pulse width modulation.  Then you would be able to use software like LabVIEW to integrate the area under the waveform to get an accurate current calculation.   The second method would be to put an averaging capacitor on the output of the current sensor with a weak drain to ground like 10k Ohm.  You could them calibrate the output value using a known good standard like reading the voltage drop across a shunt with an O-scope.  Since this sensor has a 3us response time, you will be able to monitor PWM current up to about 300,000Hz .
