Low cost Current sensor, +/- 800A, Simple interface, $15

[methods]

We are talking about non-contact isolated current sensors for higher current stuff.

Generally speaking these are $50 to $150
As price drops they get harder to work with... like they need +/-15V excitation, they have a fussy current output instead of voltage output, etc.

What you want is:
* 3 pins
* 5V input
* Output that is 2.5V +/- 1.5V to span 1V to 4V... loaded down to 10K where your uController is running 5V with a stable reference of about 4.2V on the ADC-REF
* Bidirectional
* DC capable... but fast acting... where anything that happens faster than say... a ms is not important... so.. 1khz absolute minimum

No idea of the quality on these... but the damn price is right

Requirement:
Current sensor for ranges 200A to 800A
Ideally a dual output with something 1/10th in the same package (one to see charge, one to see discharge)

Intent:
Tag my CAN board on the front of it
Wire directly to the chip on the CAN board
Bring out 4 wires: 12V, GND, CANHI, CANLO
Modular CAN enabled current sensor for EV
IP66 minimum rating
Target $20 value add to sensor, $20 sensor, 50% markup, $80 would be dirt cheap for an evil awesome part.

Must be something wrong as this sensors is TOO CHEAP

As I am sure they are getting them very cheap

thanks,

Note: Second sensor has IP rated connections... which brings up cost a touch... but is a very good sign.

No perfect match, but likely this manufacturer:

The DHAB family has a dual current range. It gives you the choice of having different peak currents (from +/- 20A up to +/- 600A) in the same housing.

The CAB family communicates through the standard CAN bus.
