Haefely

Haefely is a global leader in the manufacturing of electrical, high voltage and EMC test equipment. The Pfiffner Group acquired Haefely in 2019. Since its founding by Emil Haefely in 1904, Haefely has grown to be recognized as a manufacturing giant and industry innovator in high voltage and EMC test instruments. The company grew exponentially in both scope of equipment and worldwide presence during its time as a segment of Hubbell, then known as Haefely Hipotronics.

Haefely is divided into three distinct segments. Haefely High Voltage is renowned for its high voltage test systems like the DTTS Series transformer test sets, PGR test systems, and PSK & PZT AC test transformers. Haefely Tettex designs electrical measurement instruments like transformer test sets and partial discharge testers ideal for industrial electrical testing. Haefely EMC is known for its cutting-edge AXOS transient immunity generators, like the AXOS5 and the AXOS8, industry-leading ESD guns like the ONYX 16kV and 30kV ESD simulators, EMC antennas like the MSurge, and more.

ATEC carries a comprehensive inventory of Haefely EMC test equipment ranging from flagship models like the AXOS8 to ESD guns and test systems that cover specific IEC-61000 standards.
