FAQ
What is the Ltech LM-75-24-G1T2 designed for?
The Ltech LM-75-24-G1T2 is a 75W constant-voltage 24VDC Triac driver for internal lighting applications. It is intended for LED lighting systems that need phase-cut dimming and supports both Push DIM and Triac/ELV dimming.
What dimming methods does the LM-75-24-G1T2 support?
This model supports leading-edge (Triac) and trailing-edge (ELV) phase-cut dimming. It also supports Push DIM, giving more flexibility for lighting control in compatible applications.
How smooth is the dimming performance on this 24V driver?
The LM-75-24-G1T2 offers a 0 to 100% dimming range and can start LEDs at 0.1%. It is described as flicker-free across the 0 to 100% range in line with IEEE 1789, which makes it suitable for applications where stable light output matters.
What output does the Ltech LM-75-24-G1T2 provide?
This driver provides a 24VDC constant-voltage output with a 75W power rating. Its rated current is 3.125A, matching applications that require a 24V constant-voltage driver within that power range.
What protection features are included in the LM-75-24-G1T2?
The LM-75-24-G1T2 includes overload, over-temperature, short-circuit, and over-voltage protection. Overload, over-temperature, and short-circuit protections recover automatically, while over-voltage protection requires re-powering to recover.
What operating environment is this driver rated for?
This model is rated for ambient temperatures from -20°C to 50°C. It is specified for internal lights application, so it is intended for indoor use rather than exposed outdoor environments.
What makes this model different from a basic non-dimming 24V power supply?
Unlike a basic 24V constant-voltage power supply, the LM-75-24-G1T2 is built specifically for dimmable LED lighting applications. It adds phase-cut dimming support, Push DIM capability, flicker-free dimming performance, and built-in protection features tailored to lighting use.
What warranty is offered on the Ltech LM-75-24-G1T2?
The LM-75-24-G1T2 is designed for long-life operation with high-quality components. It features a robust protection suite and meets safety standards IEC/EN61347-1 and IEC/EN61347-2-13.
