FAQ

What type of LED application is the Lifud LF-GIF040YS1050H designed for?

The LF-GIF040YS1050H is a constant-current LED driver intended for LED applications that require 1050mA output. Its rated output range is 33-40V, so it suits fixtures or modules designed to operate within that constant-current window. It is a non-dimmable model for applications where simple on/off operation is required.

Is the Lifud LF-GIF040YS1050H dimmable?

No, this model is non-dimmable. It is intended for installations where dimming control is not needed and stable constant-current output is the priority. Buyers needing dimming should compare it against a dimmable driver rather than this specific model.

What are the main electrical specifications of the LF-GIF040YS1050H?

This LED driver is rated at 40W with a constant output current of 1050mA. Its output voltage is listed as 33-40V, and the rated AC input voltage is 220-240Vac with a voltage limit of 198-264Vac. These figures make it important to match the driver to LED loads designed for that current and voltage range.

Can the LF-GIF040YS1050H be used in demanding temperature conditions?

This model has an operating temperature range of -30°C to +45°C. That makes it suitable for environments that may experience cold conditions, provided the overall application remains within the stated limits. Buyers should still confirm the full fixture and enclosure also support the same temperature range.

What protection features does the Lifud LF-GIF040YS1050H include?

The LF-GIF040YS1050H includes open-circuit protection below 55V and short-circuit protection with hiccup mode and auto-recovery. These features help protect the driver during fault conditions. It also specifies an inrush current of no more than 27A at 154uS.

Is the LF-GIF040YS1050H suitable for indoor use?

This driver is rated IP20, which generally aligns with indoor use in protected environments. IP20 does not indicate protection against water exposure, so it should be selected for applications where that rating is appropriate. Its compact dimensions of 115 x 41 x 28 mm can also help where internal space is limited.

What certifications or compliance standards are listed for this LED driver?

The LF-GIF040YS1050H carries RoHS, ENEC, CE, CB, UKCA, CCC, and RCM certification marks. It complies with safety standards EN61347-1:2015, EN 61347-2-13:2014/A1:2017, and EN 62384 2016/A1:2009, along with EMI standard EN55015.

What warranty is offered for the Lifud LF-GIF040YS1050H?

This model is listed with a 5-year warranty, provided the case temperature (Tc) remains at or below 89°C. This warranty period applies under the specified thermal conditions.
