daft question on LED indicators and high VDC

[dsc]

Thanks for the replies, I was thinking resistor, but that's a lot of watts, so thought that maybe there's a better idea. Another way of approaching this is ditching the 68VDC and getting a 42VDC as this is for a pretty small Nema 23 (SY57STH56_2004A) with a DM856 driver, this would then mean less dissipation needed, although also means more monies to spend. With the Zener costing 36p I might just give that a go and leave the 68VDC PSU:)

Cheers,
