Product Overview
LESR 15-NP is a LESR series current transducer for the electronic measurement of current: DC, AC, pulsed, with galvanic separation between the primary and the secondary circuit. 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) and power supplies for welding applications, solar inverters.
- IEC 61800-5-1: 2007, IEC 62109-1: 2010, IEC 62477-1: 2012, UL 508:2013 standards
- Closed loop multi-range current transducer, voltage output
- Unipolar supply voltage, compact design for PCB mounting
