ISOLATED AC CURRENT MONITOR

Published:2012/9/4 3:59:00 Author:Ecco | Keyword: ISOLATED , AC , CURRENT , MONITOR | From:SeekIC

This circuit uses a small AC current transformer from Magnetek to produce an isolated voltage proportional to the AC current in the primary winding. The transformer contains a single turn primary with a low 0.001-ohm resistance. It can easily handle 30 amps of AC current and provides at least 500vac of isolation. With the components shown, the output AC voltage is scaled so 1 amp of current produces 100mv of AC voltage. Source: discovercircuits
