Electronics-Salon DIN Rail Mount +/-20Amp AC/DC Current Sensor Module, based on ACS712: Amazon.com: Industrial & Scientific

Posted by jpluimers on 2020/12/24

For my link archive (this DIN rail device allow sensing current used by a circuit; models for 5A/20A/30A).

Thanks Matthijs ter Woord for pointing me to this.

Schematics show it uses an LM317 linear voltage regulator (to get 5V out of a 8V-35V range) next to the ACS712 current sensor (based on the [WayBack] Hall effect) available in 5A, 20A and 30A varieties.
