Test Equipment


The ultimate compact power supply for professional testing and experimentation

This project is launching soon.

Coming Soon
You'll be notified about news and stock updates for this project.

SourcePure is an easy-to-use, compact power supply unit that accepts a wide array of power inputs and outputs reliable, stable 1.8, 3.3, and 5 VDC power.

Professionals and hardware hobbyists need reliable power. Whether you’re testing a new PCB design or troubleshooting sensitive analog circuits, everything starts with a good power supply unit. That’s why SourcePure was designed to use precision-filtered components that won’t inject additional noise.

An included 9 V rechargeable lithium battery makes SourcePure ideal for different situations. No matter if you need to test your board at the lab, power your circuit in the field, or work from a library—you don’t need to carry a heavy power supply any more!

Verifiable High Precision Output

Although it is a compact and portable power supply, SourcePure has been designed to output 1.8 VDC, 3.3 VDC, and 5 VDC of extremely clean power. We have validated it, and 20 pre-production units are currently in the wild with testers. But you don’t have to believe us—take a look at the readings at each of its outputs from our Fluke 289 TrueRMS Multimeter:

Measuring output 1.8 VDC while connected to a dynamic load:

Ultra High PSRR: 83 dB @ 100 Hz, 85 dB @ 1 KHz, 80 dB @ 10 KHz, 61 dB @ 100 KHz (Measured at 10 mA current)

Ultra Low Noise: 9 uVRMS

Measuring 3.3 VDC output while connected to a dynamic load:

Ultra High PSRR: 60 dB @ 1 KHz, 45 dB @ 100 KHz, 30 dB @ 1 MHz (Measured at 1 A current)

Ultra Low Noise: 30 uVRMS

Measuring 5 VDC output while connected to a dynamic load:

3 A, super high efficient switching mode power supply (switching frequency 50 kHz - 1.5 MHz)

Features & Specifications

Supported outputs:

Supported inputs: 8 VDC to 28 VDC

Main Components:

Included with each SourcePure will be a 9 V 3000 mAH rechargeable battery, a durable aluminum case, and an assortment of useful leads seen below:

Open Source

The schematics for SourcePure will be made public when crowdfunding begins.
