user181 Posted November 14, 2023 Posted November 14, 2023 We recently had a power outage and my ISY994i did not come back online afterward. The "power" LED came on but otherwise the device seemed completely dead. As others have experienced, I isolated the issue to the wall wart power supply. It is a 5VDC supply, and even though I measured ~4.99V with a multimeter, the ISY did not work. I have temporarily substituted a universal wall wart (with selectable output voltage) and the ISY works fine. I noticed the UD website sells a replacement power supply which is 12V, and have ordered one. I saw other posts here that mention that the ISY994i accepts a range of input voltage, but I would like to know if there are specs published somewhere to confirm this. I just want to make sure that it is OK to power it with 12V, and find out if there are any caveats. Thanks!

Here is what UDI has published for power supplies for ISY994: https://wiki.universal-devices.com/index.php?title=Main_Page#Front_Panel_LEDs/Lights 1
Brian H Posted November 14, 2023 Posted November 14, 2023 The one UDI sells last time I looked was 12V 2A. It has a wide voltage range. My failed one was 5V 500mA but it is recommended you go with 1 or 2 amps. 5V and 12V seem to be the choice of many. 1
