30A inline current sensor (ratiometric)

This product is not yet for sale. If you are interested in evaluating a beta version in your application, please reach out at support@four-forty.com

The 30A inline current sensor (ratiometric) makes isolated current measurements easy. This compact board breaks out the popular ACS711 hall-effect linear current sensor to give you an isolated, bipolar signal. Please note that this sensor is ratiometric, and will require a clean 3-5.5V rail to produce accurate measurements.

Features:

• Tiny 0.35 x 0.70″ (8.9 x 17.8mm) size, easily heatshrink-able onto an existing wire
• +/- 31A optimized accuracy range, 100A surge
• 45 mV/A sensitivity
• 3-5.5V supply voltage range
•  Fault pin broken out
