What INTREXIS does

intreXis AG is a privately-held Swiss electronics manufacturer founded in 2005 and headquartered in Neuhausen am Rheinfall, Switzerland. The company designs and sells DC/DC and AC/DC power converters engineered primarily for railway on-board applications, with secondary offerings in medical-grade power conversion and ruggedized converters for military/defense use. Its core technology addresses the demanding electrical environment of rail vehicles: ultra-wide input voltage ranges (14.4 to 154 VDC, >10:1 ratio) supporting nominal 24V/36V/48V/72V/110V systems, 750V and 1500V overhead-line input variants, extended operating temperatures of -50°C to +85°C without derating, galvanic isolation up to 16.8 kVAC, active inrush current limiting, and an active surge limiter using SiC Schottky diodes for protection against long and repeated surge impulses on 750V/1500V overhead line power. The product range is delivered across multiple form factors — chassis mount, open frame, PCB mount, DIN Rail (including an ultra-narrow 28 mm / 230 g variant), 19" Eurocard, and high-isolation formats — and is complemented by uninterruptible power supplies, USB-C PD chargers, battery-start units, custom developments, and retrofit solutions for legacy rolling stock. All railway products are certified to EN 50155 (2021), IEC 60571 (2012), EN 45545-2 fire protection, EMV 06 EMC, EN 62368-1 safety, and EN 61373:2010 shock/vibration, with environmental compliance under RoHS, REACH, and conflict-mineral reporting.

The firm operates with a headcount of 11-50 staff and claims to export to more than thirty countries while serving "all major train manufacturers worldwide" along with leading system suppliers and railway operating companies. Revenue is generated through direct sale of hardware units and custom-engineered converter solutions; pricing is handled by quotation rather than published list price. The go-to-market is sales-led and direct, driven by the company website's parametric product search, datasheets, and 3D STEP models, with no disclosed distributor or reseller network. Customer engagement is deepened through long-cycle custom development and retrofit programs for aging rail fleets, embedding the company's converters into qualified bills of materials for both new-build and refurbishment programs.

Recent activity includes launches of the 28 mm DIN-Rail IC27x family (2025), a 50W no-wiring converter (February 2026), an IC502-3 battery-start unit explicitly targeted at North American rail vehicles (May 2026), and expanded USB-C PD passenger chargers, framed within a 20th-anniversary announcement of the largest development project in company history.

Core offering

intreXis AG designs, manufactures and sells DC/DC and AC/DC power converters (Powersupplies) engineered primarily for railway (rolling stock) applications, with additional product lines for medical, military and industrial uses. The portfolio spans standard catalog converters in multiple form factors, custom-engineered units, retrofit replacements for legacy systems, uninterruptible power supplies (UPS), and USB-PD passenger chargers. All products comply with railway standards EN 50155, IEC 60571, EN 45545 and EN 62368-1.

Product overview

intrexIS AG offers the most comprehensive portfolio of DC/DC and AC/DC converters specifically designed for railway applications. The product lineup centers on standard DC/DC converters with input voltages of 24V, 36V, 72V, 110V, 750V, and 1500V available in multiple form factors (Chassis mount, Open frame, PCB Mount, DIN Rail, 19" Eurocard, and High isolation variants), complemented by AC/DC converters (115/230VAC input) for railway environments. Beyond standard products, the portfolio includes custom-designed converters, retrofit solutions for legacy systems, medical-grade power supplies, uninterruptible power supplies (UPS), and USB chargers for passenger and crew facilities. The company also produces specialized battery start units for 750VDC overhead line applications. All products comply with railway standards including EN 50155 and IEC 60571, with additional certifications for fire protection (EN45545), EMC (EMV 06), and product safety (EN 62368-1).
