PEM Announcements and Updates

New from PEM - CWTUM-S
Designed to keep pace with increasingly compact and lower profile power devices, the CWTUM-S ultra-thin 1.2mm coil can slip into compact layouts in energy dense circuits. Despite a thickness of just 1.2mm it retains a 1.2kV peak insulation capability and 125oC maximum operating temperature. Its bandwidth, spanning a few Hz to 30MHz, captures low and high frequencies crucial for in-depth performance analysis, while its peak current range enables its use monitoring in low-power devices through to high power converters.

CWTMini50HF to supersede the CWTMiniHF
From January 2025, the CWTMini50HF will supersede the CWTMiniHF in our CWT range. CWTMini50HF is a significant evolution of the CWTMiniHF and delivers improved high frequency performance with a faster response time for transient measurements. The CWTMini50HF range has been expanded to include, 2kV and 5kV peak coil insulation voltages, as well as longer coil lengths. This upgrade underscores PEM's commitment to advancing technology and meeting the evolving needs of the industry.

The history of the Rogowski coil (1912 - 1950)
Read about the early history of the Rogowski coil, from its theoretical proposal in 1912 as a current measurement device to its gradual refinement by 1950. Over four decades, the coil’s design and principles were studied, yet it remained a work in progress. Despite its experimental nature, it represented a valuable step forward in electrical engineering, sparking interest for future development.
