At my company, we are seeing massive failures of the Phoenix Uno power supply. This is a small 400-500v input and 24VDC output power supply. We connect it at 480V.
Within an installed base somewhere around 20,000 units, I would estimate we have had somewhere around 500 fail after being in service approximately 2-3 years. This seems low on the surface, but the failure rate is still well above the manufacturer's rated MTBF.
The issue internally is always a blown MOV.
Is anyone else using this unit? Are you experiencing failures?
