HEIDEN power GmbH

What HEIDEN power GmbH does

HEIDEN power GmbH is a privately held German specialty power-electronics company founded in 1972 and headquartered in Pürgen, Bavaria. It designs, distributes and integrates programmable DC power supplies, AC power sources, bidirectional electronic loads, battery testers, and complete test systems for industrial and R&D customers across battery/E-mobility, electroplating, Power-to-X hydrogen, aerospace, and general power-electronics applications. Its proprietary portfolio spans from 1.8 kW laboratory supplies up to 2000 kVA AC source systems, with a distinctive specialization in very high-current DC (up to 10,000 A per rack, water-cooled) and bidirectional source-sink test systems (HTS17, HTS25) that feed absorbed power back into the grid. Recent additions include the HEA-BIM20005 electrochemical-impedance-spectroscopy battery tester (2025) and a 1500 V HTS25 model targeting next-generation EV, e-aircraft, and grid-storage architectures. The company complements its own products with German and European OEM lines it distributes: REGATRON DC sources and grid simulators, PREEN AC sources, TDK-Lambda GENESYS+ programmable DC supplies, Infratek power analyzers, and EA Elektro-Automatik regenerative loads.

The business model combines one-time hardware sales (catalog products and stock/used equipment at €400 to €289,000 ASPs) with custom engineering and system integration for individually designed racks and turnkey test solutions. GTM is direct B2B with personalized technical consultation, supported by a heavy trade-show presence (electronica, PCIM, Intersolar, Battery & Power World, Smart Energy Week Tokyo, FuelCell Forum). Marketing relies on a 107-page product catalog, a multilingual website, CleverReach newsletters, and SEO rather than paid digital advertising. The company has delivered more than 130 HTS source-sink test systems to "renowned customers" over its history, with disclosed references including Schaeffler Engineering, TUfast Racing Team, and (previously) Lilium. Operating geographies span Germany, Austria, Switzerland, Netherlands, France, USA and Japan. A related entity, HEIDEN electronics GmbH (Augsburg commercial register B15917), is co-located at the same address and performs development and production, while HEIDEN power GmbH (B20756) handles sales and distribution under managing director Dipl.-Ing. Franz J. Dorfner. No outside investors, acquisitions, or public-market activity are indicated.

The company profile is that of a classic German Mittelstand engineering firm: long-lived (53 years), technically deep in a narrow niche (high-current DC and bidirectional test systems), privately held by management, geographically concentrated in DACH with selective export reach, and supported by durable OEM distribution partnerships that supply complementary product lines (AC sources, regenerative loads, analyzers) the company does not manufacture itself. Revenue is not publicly disclosed, employee headcount in the available data is listed at five for the sales entity (with the related production entity likely adding capacity), and the active 2025 product roadmap and Japanese trade-show expansion indicate modest but real investment in growth.
