600A/5A CT with ACS712 Module and Arduino

Hi Everyone,

Has any one of you tried integrating a CT with ACS712 5A module? The CT (TYCKT-36) has a rated input of 600A and rated output of 5A. I'm not sure if ACS712-5A can handle the current coming from the CT. Please send some insights. Thank you!

Could you tell us what CT stands for?

Their datasheets would tell a lot.

Use an ACS712-10A (or 20A) so it can handle the whole range 0..5A including possible overshoot.

What is the accuracy / resolution you need?

First you must find the burden of your CT. Look at the datasheet.
Then add the appropriate burden in series with the ACS712 and connect to CT output.

Current Transformer

I would take some safety margins. Peak currents can be larger than max current without damage...

Also: what load uses 600A?

Hi, @prec-asdfjkl
Welcome to the forum.

Can you please tell us your electronics, programming, arduino, hardware experience?

Are you aware of Burden Resistors that are needed with Current Transformers.

A link to data/specs of the CT would help.

Thanks.. Tom.... :smiley: :+1: :coffee: :australia:

yea im aware of the concept of burden resistors but i don't have a deep understanding about it

here's the link of the CT im using
400A 500A 600A Kct-36 Current Sensor Split Core Current Transformer - Current Transformer and Split Core

im not sure if the CT has a built in burden resistor inside

400A 500A 600A Kct-36 Current Sensor Split Core Current Transformer - Current Transformer and Split Core

yea, thanks i will consider that.

just need to capture up to 600A.

generally if the CT has a stated rating, e.g. 10A, 100A, 600A, etc, it will have a onboard burden resistor of a suitable size

if it does not have a burden resistor be careful - an open circuit CT can generate an output of tens of thousands of volts

A CT with a 5A or 1A output do not include a burden but what burden is required for your particular CT is unknown.
The information on the webpage is for a CT with a current ratio of 600A/50mA not 600A/5A.

I suggest you contact the seller and ask what the CT burden is.
