Hey guys, great forum.

I am developing an LED lighting controller which will be powered from a UL/ULC listed class 2 power supply. I can live with a power supply output of 12V 1A, but would rather have 12V 5A.

I can see that UL has regulations that could be applied such as UL2108 and UL8750 but I would obviously rather not go this route if it isn't needed.

It looks like some jurisdictions spell it out and say that this setup is safe and no listing is needed.

The controller will be enclosed in a metal cabinet and there will be a number of 12 volt 20mA led lights connected. Obviously heating will not be an issue since the LED lights will not give off any heat.

Any ideas?

The NEC requires it be listed.


411.3 Listing Required. Lighting systems operating at 30
volts or less shall comply with 411.3(A) or 411.3(B).


(A) Listed System. Lighting systems operating at 30 volts
or less shall be listed as a complete system. The luminaires,
power supply, and luminaire fittings (including the exposed
bare conductors) of an exposed bare conductor lighting system
shall be listed for the use as part of the same identified
lighting system.


(B) Assembly of Listed Parts. A lighting system assembled
from the following listed parts shall be permitted:

(1) Low-voltage luminaires

(2) Low-voltage luminaire power supply

(3) Class 2 power supply

(4) Low-voltage luminaire fittings

(5) Cord (secondary circuit) for which the luminaires and
power supply are listed for use

(6) Cable, conductors in conduit, or other fixed wiring
method for the secondary circuit

The luminaires, power supply, and luminaire fittings
(including the exposed bare conductors) of an exposed bare
conductor lighting system shall be listed for use as part of
the same identified lighting system.
