FAQ

Question?
What is the PC/104 standard?

Answer

PC/104 is a standard for embedded computer systems that defines both a form factor and a bus. It allows for stacking of expansion modules, like this power supply, creating a compact and rugged computer system without the need for a backplane.

Question?
Can this HE104 power supply be used in non-vehicle applications?

Answer

Yes, absolutely. While designed for the wide and often unstable voltage ranges found in vehicles (6-40VDC), its robust design and wide input range make it suitable for various industrial, embedded, or battery-powered systems that require stable +5V, -5V, +12V, and -12V outputs.

Question?
What is the significance of the ‘SPECTRO-2’ part number suffix?

Answer

The ‘SPECTRO-2’ suffix indicates that this is a specific variant of the standard HE104 model, likely customized for a particular customer or application. While the core functionality is the same, there might be minor modifications in components or layout. It is always best to verify compatibility with your specific system requirements.
