Reducing voltage to power smaller devices
 
Hello all,

I have a PowerSupply that supplies 48V. It is great for an iCharger. However, I want to use it to power a SkyRC motor analyzer which maxes out somewhere in the range of 8.4 V. I have tried dialing down the V output on the front, but the lowest I got to was ~45V. Is there a product available to help me reduce the output voltage so I can use the same power supply to power the smaller devices too?

Thanks.

why go thru the added expense. just charge a 2 cell lipo and use it to power analyzer

This is a complete adjustable power supply which can take about 60v. There are many versions based on the current rate, the 5015 can handke 15A. There are also nice cases to be found.

Also there are plenty of DC-DC converters to be found, search on ebay/aliexpress/banggood/wish/etc to "dc dc converter" and look at the specs.

Sometime I can't see the forest for the trees.

Because with a constant voltage power supply, you can compare motor changes without worrying about the battery voltage dropping.
