We worked with an established power supply company in China to make this somewhat hard to find power supply. We took their existing supply design (which is very good in its own right) and had them make some minor changes to bring the specs up slightly.

This is the same power supply we use in our RPS. It has several circuit protections, an LED power indicator and a capacity of 500ma per channel - 10 watts total.

• AC Input 85-265V - accepts any standard wall current
• 85% efficient -  by far the best performance of any comparable supply. It makes for cooler operation and better energy efficiency.
• Load regulation within 1%
• Overload, Over-Voltage and Short Circuit Protection
• Small footprint: 76x40mm fits many housings
• Pin spacing 3.96mm
• 1 year warranty

As with all DIY pieces, safety is paramount. While this component is simple - working with electricity is always dangerous. If you do not have a strong knowledge of what you are attempting - do not attempt! And if you do, exercise caution at all times.
