Q1: What is the difference between the N series and the NT series?
A: The N Series 12V Outdoor LED Power Supply is designed for constant, full-brightness output and cannot be dimmed. The NT series is specifically engineered for Triac/Phase-cut dimming. For applications where dimming is not required, the N series offers higher cost-performance and simplified maintenance.
A: No. NEMA 3R Rated 12V Power Supply protection is designed for outdoor use to protect against rain, sleet, and snow. It is ideal for vertical mounting in sheltered outdoor locations. For underwater use, an IP68 rated driver would be required.
A: Yes. Because it is a UL Listed Class 2 Aluminum Adapter, it meets the strict energy-limiting safety requirements for various low-voltage equipment types in the USA and Canada, including many non-patient-contact medical peripheral applications.
