CASR 50-NP

CASR 50-NP is a CASR series current transducer for the electronic measurement of current: DC, AC, pulsed.., with galvanic separation between the primary and the secondary circuit. Standards include EN 50178: 1997, IEC 60950-1: 2006, IEC 61010-1: 2010, IEC 61326-1: 2012, and UL 508: 2013. Typical applications include AC variable speed and servo motor drives, static converters for DC motor drives, battery-supplied applications, uninterruptible Power Supplies (UPS), switched-mode power supplies (SMPS), power supplies for welding applications and solar inverters.

• Closed loop (compensated) multi-range current transducer
