Hi Kurt, I believe that under the R&TTE Directive, now in full bloom, the requirements of the LVD apply without the voltage limits.
For North America, UL 1950, third edition/CAN CSA C22.2 No. 950-M95 (the binational standard) would likely be your best fit. My 2 Cents and not that of my current employer.

All outputs will be 12 VDC or less. This is a commercial unit and will not be sold to consumers. In Europe it would fall outside the scope of the LVD as it starts at 75V for DC powered equipment and this will be powered by 48 VDC. Does anyone know if there any other safety standards required in Europe for this type of equipment? It does appear that safety testing and listing is required by OSHA for use in a U.S. workplace. According to OSHA Standard 1910 Subpart S all "electric utilization equipment" is required to be "approved" which in most cases means Listing by a NRTL. In 1920.399 OSHA defines "electric utilization equipment" as equipment which uses electrical energy for mechanical, chemical, heating, lighting, or similar useful purpose. My interpretation of this is that any equipment which uses electricity, AC or DC, would need to be tested and Listed. Is my interpretation of the OSHA requirements correct? What about requirements for Canada? Any insights into these questions would be greatly appreciated.
