Product Description

• The DC-DC converter is an adjustable step up / step down 3A switching DC-DC converter.
• The output is adjustable from 1.25 to 28V. The output voltage is set with a dial, similar to the volume control on a stereo system.
• Once the output voltage is set, it does not matter whether input voltage is higher, lower, or the same as the desired output.
• On board 3 digit 7-segment display that can be toggled between showing output voltage and current.
• Input power and output loads are connected with easy connected terminals, so no soldering is necessary.
• Additional circuitry ensures that the product won’t be damaged by reversed power connections, or by overloading.
