Moonshot Jr's Triple-Output Power Supply Offers Fixed and Adjustable Outputs up to 37V

Designed for flexibility, the PCB accepts up to 40V in and outputs 1.23-37V across an adjustable output plus 5V and 3.3V fixed outputs.

STEM specialist Moonshot Jr has launched a crowdfunding campaign for a triple-output adjustable power supply, itself powered by a two-pin header or USB input.

"Most hardware designs and Industrial products need some source of DC power supply to test in labs. Current solutions either have bulky and expensive bench power supplies that typically has only one one output power. Other wall mount power supplies provide only one output power supply," Moonshot Jr's Rangoly Jain explains. "This is where the Moonshots Triple Adjustable Power supply Board comes in play."

"The current ratings of the power supply is dictated by the specification of the LM2586 and the limitation of the Input Power supply. We recommend using a high current rating wall mount (5V, 3.0A) charger if using the USB connector for Input. If two Pin header is used, a high rating wall mount power supply could be used. The Output consists of two fixed power supplies at 3.3V and 1.5V. There is one adjustable power supply and its output voltage can be adjusted using a potentiometer."

The design allows for a maximum input voltage of 40V, while the output voltage can be controlled from as low as 1.23V up to 37V ±4 percent. There's 3A of output current, and both over-current and thermal limits in place to protect the system.

The board is now available to back on Kickstarter, priced at $20 per unit with delivery expected as early as September this year.
