Power supplies

Power management is GRE's core competency. Our in-house power electronics engineering team has 30 years of experience on custom/semi-custom power supply design and development.

We manufacture Printed circuit boards (PCBs) and complete box assemblies at our vertically integrated, lead-free and ISO 9001:2008 certified facilities. Our full suite of services range from board layouts, BOM analysis & alternative component selection, to design for manufacturability and testing analysis (DFM/DFT), to prototyping, functional board testing and 3rd party compliance.


Examples of power management products manufactured include: switch mode power supplies (AC-DC, DC-DC conversion), linear adaptors, car adapters and inverters, as well as transformers, chokes and coils used in telecommunication, HVAC/refrigeration and automotive applications. In the past ten years, our portfolio has expanded to cover higher voltage/wattage power management systems including LED drivers and EV charging - for automotive and industrial lighting applications.
