What iseg - High Voltage. Exactly. does

iseg is a German specialty manufacturer of precision high voltage power supplies (HVPS) for industrial and scientific research applications, headquartered in Radeberg, Saxony, and founded in 1995. The company designs and produces compact DC/DC modules, AC/DC rack and benchtop units, and scalable multichannel HV systems in industry-standard formats (19" Eurocassette, NIM, VME), with differentiation grounded in ultra-low ripple and noise specifications down to 5×10⁻⁷ of the adjusted output voltage. Its two legal entities — iseg Spezialelektronik GmbH and iseg Leistungselektronik Sachsen GmbH — are both ISO 9001:2015 certified and operate as a vertically integrated German Mittelstand manufacturer.

The product portfolio addresses detector bias supplies for radiation and particle experiments, source measure units (SMU), capacitor charging, e-beam coating, ion beam, X-ray, photodetection, and metrology/inspection applications. iseg sells through direct, consultation-based sales with global reach, supported by daily technical support (8:00–17:00 CET), a downloadable and interactive catalog, a VR-based virtual showroom, and a dedicated support ticket / RMA infrastructure. Named customers include CERN, FRIB, NSCL, TU-Dresden, Beamtec, Mesacon, SPECTRO/Ametek, Vacutec, and Thermo Scientific, spanning research institutions, scientific instrument OEMs, and industrial manufacturing equipment builders.

The company is privately held with approximately 11 employees and no disclosed external funding or parent company. There are no public revenue figures, no funding rounds, and no M&A activity in the record. The business model is hardware sales of customized, high-reliability HV power supplies with a 3-year standard warranty extendable to 5 years, reflecting a niche, OEM- and research-embedded commercial posture rather than a high-volume consumer or SMB model.
