FAQ
What is the Ltech LM-150-24-G2D2 designed for?
The LM-150-24-G2D2 is a 150W constant voltage LED driver for 24VDC lighting systems that use DALI2 DT8 control. It is intended for tunable white applications where both dimming and color temperature adjustment are needed. This model is suited to internal lighting projects that require stable output and advanced control.
Does this model support tunable white lighting control?
Yes. This driver supports DALI DT8 tunable white control and is described as a DIM and color temperature adjusting driver. It also has 2 independently SELV constant voltage output channels and a color temperature adjustment range of 2500-6000K.
What are the key electrical specifications of the LM-150-24-G2D2?
This model is rated at 150W output power with a 24VDC output and 6.25A rated current. The product description also states up to 93% efficiency, power factor greater than 0.98, and THD below 6%. These specifications make it a strong fit for commercial-grade LED lighting applications that need efficient constant voltage performance.
How low can this LED driver dim?
The stated dimming range is 0-100%, with LED start possible at 0.1%. That makes this model suitable for projects where very low light levels and smooth adjustment are important. The description also specifies flicker-free performance across the color temperature adjustment range.
Is the LM-150-24-G2D2 suitable for demanding environments?
This driver is specified for ambient temperatures from -20°C to 50°C. It also includes intelligent thermal management and automatic recovery protection for over-heat, over-voltage, overload, and short circuit events. Those features make it appropriate for demanding indoor applications where durability and protection matter.
What distinguishes this driver from a standard non-DALI 24V LED driver?
The main difference is its support for DALI2 DT8 tunable white control rather than basic fixed-output power delivery. This model is built for both dimming and color temperature adjustment while maintaining constant power to keep the same brightness as color temperature changes. It also adds high efficiency and very low standby power consumption.
