What it does:
Clips around a cable to measure AC current. Outputs a 0-10V DC signal.

The ACCS-010 is a self powered AC current sensor with no external supply required. It converts a high current AC signal into an industry standard 0–10V DC isolated output. The ACCS-010 can be used to monitor AC current loads in switchboards, motors and machines, and is principally used for machine protection and energy monitoring.
