FAQ
What is the Ltech SN-45-300-1050-G1NF designed for?
The SN-45-300-1050-G1NF is a constant current LED driver for professional indoor lighting applications. It is intended for luminaires that need precise current control and supports use with Class I, II, and III fixtures.
What makes this LED driver different from fixed-current models?
This model allows the output current to be adjusted from 300mA to 1050mA. That gives more flexibility than a fixed-current driver when matching one driver model to different luminaire requirements.
What are the main electrical ratings of the SN-45-300-1050-G1NF?
This driver is rated at 45W power with an output voltage range of 9-42Vdc. The adjustable current range is 300-1050mA.
Is the SN-45-300-1050-G1NF dimmable?
The product data lists this model as non-dimmable. It does not support dimming control interfaces.
Can this driver be used in demanding indoor lighting environments?
It is built for indoor professional lighting use and has an operating temperature range of -20°C to 45°C. That makes it suitable for many commercial and architectural indoor applications within those environmental limits.
What warranty and physical size considerations apply to this model?
The SN-45-300-1050-G1NF comes with a 5-year warranty. Its listed weight is 112g, which supports its positioning as an ultra-small driver for space-conscious luminaire designs.
