What IIE does

iie GmbH & Co. KG is a privately held, owner-managed German limited partnership headquartered in Soyen, Bavaria, that designs and manufactures high-performance power electronics and a separate industrial worker-guidance software platform. The company's power-electronics division produces silicon-carbide (SiC) based DC/DC converters (SR800 400 kW modules achieving 99.7% efficiency), regenerative PFC modules (PFC180 180 kW), a bundled 2.4 MW HS2400 electrolyser power cabinet, electronic ballasts for UV lamps, and pulsed laser power supplies for industrial and medical OEMs; vertical integration includes in-house CNC mechanical production alongside electronics assembly. Its Computer Aided Works (CAW) division sells the Autosynchronous Worker Guidance System®, a patented modular software platform with 30+ modules that replaces manual worker confirmation with automatic workflow synchronization at assembly, quality, logistics and shipping stations, integrating with Universal Robots cobots, Opticon scanners and Panasonic SMT/THT lines.

The company targets four primary segments: hydrogen electrolyser and energy-storage OEMs (its highest-growth focus, supported by membership in the Bavarian Hydrogen Alliance since 2020), industrial and medical laser/UV equipment manufacturers (a 30+ year heritage business), electronics-manufacturing services and manual PCB-assembly operations (via the PGMA workstation co-developed with Panasonic Connect Europe), and broader manufacturing/assembly customers adopting the CAW worker-guidance platform to digitize manual workflows amid skilled-labor shortages. Revenue is generated through direct quote-based sales of custom-configured hardware, OEM bundling of modules into multi-megawatt systems, rental/loan packages for CAW pilots, and an e-commerce storefront for select products; pricing is not publicly disclosed. Marketing is driven primarily by 5–8 European trade shows per year, complemented by LinkedIn, email newsletters and CAW blog content, while ISO 9001:2015 and EN ISO 13485:2021 certifications underpin medical-device-grade quality management.

Revenue model

1. Power Electronics Hardware Sales: Sale of custom-configured power supply units, converters, ballasts, and laser power supplies. Products are sold as individual modules (e.g., SR800 400kW DC/DC converter, PFC180 180kW inverter) and as bundled cabinet systems (e.g., HS2400 2.4MW electrolyser system). Sales are direct with quote-based pricing.
2. OEM System Integration: As an OEM partner for electrical energy storage or hydrogen electrolyser manufacturers, the company designs and manufactures custom systems. Modules are bundled into multi-megawatt systems. Engineers and programmers have created proprietary controls for system integration.
3. Worker Guidance System (Computer Aided Works): The Computer Aided Works business unit sells and rents the Autosynchronous Worker Guidance System as modular software and hardware packages. Rental/loan packages are offered to prospective buyers for testing in their production environment.
