No, of course not. UL doesn't test the brainbox part at all. The AC -> DC power supply is tested for safety by UL, but the thing powered by that power supply

No, of course not. UL doesn't test the brainbox part at all. The AC -> DC power supply is tested for safety by UL, but the thing powered by that power supply is not tested at all. Normal UL testing and listing deals with mains-powered devices, not low-voltage DC-powered devices.
