The small NUC computers such as the Beelink series are incredibly capable and have become the computer of choice for RX-888 SDR receiver installations that run ka9q-radio and wsprdaemon software. But providing these small computers with glitchless power can be a challenge. The small switching power supplies used with these computers do not store enough power to maintain their output voltage during brief power-outage events. Even the transient outages caused when a typical UPS switches into service have been seen to disrupt or reset the computer. The brief holdover provided by the TIS-1250 is sufficient to bridge the gap in power.

I’ve taken KA7OEI’s supercapacitor design and given it a few minor tweaks — it’s now available from Turn Island Systems.

I’ve got a description and test data on my Turn Island Systems website: https://turnislandsystems.com/product/tis-1250-supercap-ups/
