The ACCS-420 is a loop powered AC current sensor that converts and isolates a high current AC signal into an industry standard 4–20mA DC signal. It can be used to monitor AC current loads in switchboards, motors and machines, and is principally used for machine protection and energy monitoring.

What it does:
Clips around a cable to measure HIGH AC current. Outputs a 4-20mA signal


Casing:Split core hinged type, screw mounting case, ABS material

Dimensions (H x W x D): (66x100x32mm)

Connectors barrier strip UL 94 V-O rated
