High wattage power supplies use cooling fans, which can generate noise issues depending on the installation environment. This is especially problematic for medical devices, where quiet operation is essential.
Other applications requiring quiet operation include mixers, electron microscopes, and residential power conditioners.

Meeting high‑wattage requirements often necessitates parallel operation depending on the design conditions. This increases space, adds wiring costs, and can cause issues such as higher leakage current and noise. A single 3”×5” high‑wattage power supply eliminates these problems.

- ■Conduction Cooling
Heat generated by the power supply is dissipated to the outside through the chassis to prevent the internal temperature of the equipment from rising, supporting the overall thermal design.
- ■IEC60601-1-3 certified
- ■BF-rated, touch current 100μA or below
- ■3×5 inches size
High power density reduces space requirements and increases your design flexibility.
The fanless, high power density GHA series delivers clear advantages that drive your value creation.
- ■The GHA700F delivers 96% efficiency, supporting energy savings across various applications.
- ■The GHA700F is designed to comply with IEC61558‑2‑16 to meet the requirements of IEC60335.
- ■The isolated AUX power output simplifies logic‑circuit design and increases overall design flexibility. (Optional)
- ■The fanless design eliminates dust intake.
- ■Conduction cooling makes a sealed enclosure possible.
