Elegant solutions for power supply and battery charging applications

Castlepower has two main areas of activity in the power electronics industry:

  • Redesign of obsolete or unreliable PCB assemblies
  • Custom design for new applications

Castlepower engineers work with the customer to solve all the issues of the project requirement, including the power electronic design, (whether linear or switch-mode), interconnection, packaging and mechanical mounting or housing design.

Only highly specified and carefully sourced components are used in the design manufacturing process.

Full validation and testing is integral in the design and manufacturing process including EMC testing and certification, where appropriate.
