About Innosystem
Innosystem AG is a Swiss specialist for power supplies and power electronics based in Zeiningen. For over 30 years, the company has developed and manufactured custom switching power supplies for cases where standard power supplies fail to meet requirements due to space constraints, form factor, or safety regulations. The product portfolio includes AC/DC, DC/DC, and DC/AC converters, current and voltage sources, UPS systems, battery charging systems with battery management, and compact HV power supplies in the lower kW range up to 10 kW. Thanks to a high level of in-house manufacturing depth — including its own winding production — prototypes and products can be manufactured promptly; rapid prototyping is part of the offering, as is the integration of digital controls and redundant circuits. The company supports customers from specification through development to delivery ready for installation and assists with CE and UL certifications.
