Encapsulated isolation transformers from THS-Transformatoren Franz Hölsch GmbH are designed for applications where clean galvanic isolation and a compact design are essential. The encapsulated design in a plastic enclosure ensures a stable, closed unit that operates reliably even under more demanding environmental conditions. Especially in control systems and electrical installations where interference and external stresses play a role, this design offers clear advantages.
Technically, the transformers are consistently designed with practical application in mind: defined protection classes up to IP54, design in accordance with DIN VDE or EN 61558, and a precisely matched power range make them versatile in use. Different connection variants as well as the option for quick mounting on TS 35 rails allow straightforward integration into existing systems. This is exactly where the strength of THS lies – no overengineered solutions, but isolation transformers that simply work in everyday operation and deliver exactly what is required.
