Is the Prusa MK3 PSU UL Listed?
Title says it all... Does anyone know if the MK3 Power supply is UL Listed? Would someone be able to provide a part number? Thanks!!! 😀
Re: Is the Prusa MK3 PSU UL Listed?
A while back I did some research and found nothing that indicates the power supply is UL, nor any Canadian listings. The printer is CE marked as a LOW VOLTAGE device, I suspect testing for AC side electrical issues is limited.
To quote the Prusa CE test form: The device is not subject to the type testing ... I read that as the AC side is untested by cert labs.
The power supply is a generic INTERNAL 24v LED supply, and Prusa adds the power switch and inlet. I found a link to the PS vendor's page on one of these forums. It's a Czech company. The PS CE spec sheet and CE sheet for the printer are attached. PS is EMC (electromagnetic) and LVD certified to IEC specs, as an internal component.
