LESR 25-NP

LESR 25-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.
