What Spitzenberger & Spies does

Spitzenberger & Spies GmbH & Co. KG is a privately held German manufacturer specializing in analogue linear transistor amplifiers, AC/DC current and voltage power supplies, and 4-quadrant linear power amplifiers for industrial measurement and testing systems. Founded over 50 years ago and headquartered in Viechtach, Bavaria, the company designs products spanning 50 W to 1 MW, DC to 300 kHz, 0 to 30 kA, and 0 to 1500 V, and markets itself as one of the leading worldwide manufacturers in this niche. Its portfolio includes core amplifier series (APS, LVA, ACS, DCS, CS), complementary modules (DRU power recuperation, PV simulator, RLC load, EMS switches, pulse generators), and integrated test solutions for automotive, avionic, railway, solar, EMC, and industrial-component testing, supported by an SPS_TestManager software control layer. The company also delivers custom-engineered test benches for circuit breakers, batteries, and lamps.

The business model is built on direct enterprise sales and a global authorized distributor network covering Asia-Pacific (China, India, Japan, Korea, Singapore), North America (USA), most of Europe, and South Africa, with multiple Rohde & Schwarz country subsidiaries acting as regional resellers. Pricing is not publicly disclosed and products are typically custom-configured following technical consultation, indicating a high-touch, project-based sales motion rather than standardized SKU pricing. Customer segments include road-vehicle manufacturers, avionic suppliers, household equipment makers, industrial component producers, solar inverter developers, and (as the primary segment) certified testing laboratories and QA departments. Named reference customers include Siemens, Bosch, Miele, and VDE, with the company stating that many certified bodies worldwide rely on its equipment. The company holds DIN EN ISO 9001:2015 certification and maintains RoHS, REACH, and EICC conflict-minerals compliance, supporting OEM procurement qualification. Ownership rests with authorized directors Carl Spitzenberger and Michael Maimer through the general partner Spitzenberger & Spies Beteiligungsgesellschaft mbH, and no external venture or private equity investment is disclosed.
