What Regatron does

Regatron AG, founded in 1969, is a Swiss family-owned manufacturer of programmable DC and AC power supplies headquartered in Rorschach, Switzerland, with approximately 200 employees and wholly-owned subsidiaries in the USA (East Brunswick, NJ), Singapore, and Austria (Rankweil). The company develops and manufactures its full product portfolio in Switzerland and serves industrial manufacturers and academic research institutions globally across automotive e-mobility, battery and energy storage, renewable energy and solar inverters, smart grid, fuel cell and electrolyser, EMC, and aerospace research applications. Named customers include ETH Zurich (Swiss Federal Institute of Technology) for the CELSIUS hybrid aviation project, with the broader base described as global automobile manufacturers, suppliers, and research/testing institutes.

The technology foundation is a fully digital, modular architecture supporting parallel, series, and matrix operation, scaling from single 9–54 kW units to multi-megawatt installations exceeding 5 MW and up to 3000 VDC. The portfolio comprises two hardware families: the G5 Series — G5.IND (value-optimized industrial), G5.RSS (regenerative versatile), G5.BT (battery tester), G5.DT (drivetrain inverter tester), and G5.UNV (all-in-one universal) — and the TC Series — TC.ACS (regenerative AC grid simulator / P-HIL) and TC.GSS (multi-application DC). Supporting software includes free operating tools (G5.Control, ACSControl, TopControl) and optional application packages (G5.BatControl, SASControl, BatSim), plus turnkey charger test systems. Disclosed performance metrics include 50–200 µs transient response, 0.03–0.09% FS current accuracy, and <0.01–0.02% FS voltage accuracy, with 3x auto-ranging factor. The products are certified to a broad set of standards: EN ISO 13849 (PL c/PL e), EN 62477-1, EN 50530, LV124, LV148, ISO 16750-2, VDE-AR 4105/4110, VDE V 0124-100, IEEE 1547, UL 1741, and IEC/EN 61000-3-X / 4-X.

Regatron operates a sales-led, direct go-to-market model through its Swiss headquarters and three regional subsidiaries, backed by a worldwide partner network for local support. Revenue is generated primarily through hardware sales of programmable power supply systems and turnkey test solutions, supplemented by a rental service for selected units. Pricing is application-specific and quote-based (no public price list), with multi-year contract cadence. Customer segments are concentrated in the automotive and e-mobility sector, battery and energy storage development, renewable energy/solar inverter manufacturing, smart grid research, and industrial/academic research.

Product overview

REGATRON develops and manufactures programmable DC and AC power supplies with a modular, fully digital architecture supporting parallel, series, and matrix operation. The portfolio spans from cost-efficient basic models to systems designed for demanding test and simulation requirements, with scalable power from kilowatts up to more than 5 megawatts. The product line consists of two main hardware families: the G5 Series (G5.IND, G5.RSS, G5.BT, G5.DT, G5.UNV) covering specialized DC power supplies for industrial, regenerative, battery testing, drivetrain inverter testing, and all-in-one universal applications; and the TC Series (TC.ACS, TC.GSS) providing regenerative AC power supplies for grid simulation and P-HIL applications, and multi-application DC power supplies. Supporting software includes free operating software (G5.Control, ACSControl, TopControl) and optional application packages (G5.BatControl for battery testing automation, SASControl for solar array simulation, BatSim for battery simulation). Turnkey solutions combine hardware and pre-assembled systems for specific applications. Single-unit power ranges from approximately 9-18 kW up to 54 kW, with multi-unit systems scalable from 72 kW to over 5 MW.
