Re: Hey digital console users don't forget your UPS
A second or two? That is a relatively long time duration for a power supply loaded at rated power, with input power removed. Hold-up time seems independent of technology but a design consideration made for either.
Switching supplies can be made less sensitive to input power, often working world-wide from one design.
I don't know if digital console designers make a design effort to deal with temporary power outages, but keeping a central brain powered up, probably uses a small fraction of the total power budget, so smart management of drop-outs could allow the larger console to go dark briefly, while keeping the internal heart beating a little longer to avoid re-boot. You might still get a short drop out, but less offensive than a full boot-up. Depending on the product and your experience a UPS could be cheap insurance. Of course a cheap ups could be flaky insurance and another point of failure, part of life's ongoing IQ test.
