Hey,
We have two Nova 1700-16 switchers. We also had a power supply go out and found a replacment from Mouser Electronics (https://www.mouser.com)
It’s part number 675-GLC40-5-G It was $48 bucks. What you basicly need is a 40 Watt 5V 8A Switching Power Supply.
I changed it out in about 10 minutes. All you need it a #2 Philips screwdriver. I could walk you through it.
