You can actually go up to 120VDC (with no ripple) before you’re out of ELV - which I always find surprising. You’re probably thinking of the A/C limit which is 50V RMS.

Interesting, I thought the limit is at 60VDC.

IEC limits are 120VDC, 50VAC which quite a few countries will use (eu*/au/nz).

US NEMA/NEC is a very different standard.

60 VDC / 30 VAC in Canada per CSA Z462 (workplace electrical safety).
