SourcePure SC is a portable, easy-to-use power supply that accepts a wide array of inputs, charges an on-board supercapacitor in less than a minute, stores that charge for up to an hour, and outputs stable 1.8, 3.3, and 5 VDC power. Whether you’re an engineer, a developer, or a hobbyist, having the right tools can make all the difference. SourcePure Super Capacitance (SC) will revolutionize how you work by allowing you to take clean, reliable power on the road.

Verifiable High-Precision Output

Despite its compact nature, SourcePure SC outputs extremely clean power. We validated this in our lab, and then we sent 20 pre-production units into the wild with testers. Looking for specifics? Check out what our Fluke 289 TrueRMS Multimeter has to say about SourcePure SC’s output readings…

1.8 VDC Output While Connected to a Dynamic Load

Results:

• Ultra-high PSRR: 83 dB @ 100 Hz, 85 dB @ 1 KHz, 80 dB @ 10 KHz, 61 dB @ 100 KHz (measured at 10 mA)
• Ultra-low noise: 9 uVRMS

3.3 VDC Output While Connected To a Dynamic Load

Results:

• Ultra-high PSRR: 60 dB @ 1 KHz, 45 dB @ 100 KHz, 30 dB @ 1 MHz (measured at 1 A)
• Ultra-low noise: 30 uVRMS

5 VDC Output While Connected to a Dynamic Load

Results: Super high-efficiency, 3 A, switching-mode power supply (switching frequency 50 kHz - 1.5 MHz)

Features

• Less time waiting: Fully charge the on-board supercapacitor in under a minute.
• More time creating: That supercapacitor provides over an hour of continuous power at 1A so you can focus on your project.
