FAQ
What type of product is the LM-75-24-G1B2?
The LM-75-24-G1B2 is a 75W constant-voltage dimmable LED driver from Ltech. It provides a 24V DC output and supports Tuya Bluetooth Mesh dimming control for compatible lighting systems.
What output does this LED driver provide?
This model delivers 24V DC output with a rated current of 3.125A. Its output power range is up to 75W, making it suitable for 24V constant-voltage LED lighting loads within that rating.
Does the LM-75-24-G1B2 support dimming?
Yes, this driver is a dimmable model with Tuya Bluetooth Mesh control. It supports 0 to 100% dimming and can dim down to 0.1%, which is useful for applications that need very fine low-end light adjustment.
What applications is this 24V driver typically used for?
This model is designed for 24V constant-voltage LED lighting applications where wireless dimming is needed. It is a practical choice for commercial or residential projects using compatible 24V LED strips or fixtures that fit within the 75W capacity.
What input voltage does this driver require?
The LM-75-24-G1B2 is rated for 220-240V AC input. That makes it appropriate for regions and projects using that mains voltage range, rather than lower-voltage AC input environments.
Is this model suitable for demanding environmental conditions?
This model is rated for operation from -20°C to 50°C ambient temperature (with a case temperature limit of 80°C), which supports use across a wide temperature range. Buyers should still confirm that the overall enclosure and system design match the conditions of the final application.
What certifications and warranty does the LM-75-24-G1B2 have?
This model complies with safety standards IEC/EN61347-1 and IEC/EN61347-2-13, and EMC standards including EN55015 and EN61000-3-2. It is designed for professional lighting projects requiring these specific regulatory compliances.
