Power supply units from THS-Transformatoren Franz Hölsch GmbH stand for stable voltage supply, compact design and maximum reliability in industrial applications. Whether single-phase power supplies or three-phase power supplies, the systems are consistently designed to ensure a safe supply for control systems, machinery and electrical components. The combination of safety transformer, rectifier and well-engineered construction ensures a clean output voltage and interference-free operation, even under demanding conditions.
The quality is particularly evident in the details: insulation-tested designs in accordance with DIN EN 61558, robust enclosure variants and flexible mounting options enable use in a wide range of applications. THS-Transformatoren Franz Hölsch GmbH does not develop power supply units as off-the-shelf standard solutions, but with a clear focus on practical requirements – from conventional control technology to more complex power supply tasks. This is exactly what makes the difference: power supply units that not only function, but deliver long-term reliability and integrate seamlessly into existing systems.
