Description

The TIS-1250 provides momentary power, allowing a connected computer to operate during brief power interruptions caused by typical UPS switching transients.

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.
Obviously the TIS-1250 can by used in many other high-reliability applications, and can work with power supplies between 5 and 20 volts.

A jumper cable (with 2.5 x 5.5mm barrel plugs) is included, which is used to connect the TIS-1250 to the computer.  If your computer doesn’t use these connectors the jumper can be cut in half and be used to make adaptor cables.
