FAQ

What is the Ltech LM-100-24-G2D2 designed for?

The LM-100-24-G2D2 is a 100W 24VDC constant-voltage LED driver designed for tunable white lighting applications. It supports both dimming and color temperature adjustment, making it suitable for indoor luminaires that need variable white output.

Does this model support DALI-2 DT8 tunable white control?

Yes. This model is specified with a DALI DT8 dimming interface and is intended for tunable white control. It also lists Push DIM/CCT functionality for dimming and color temperature adjustment.

What are the main electrical specs of the LM-100-24-G2D2?

This driver is rated at 100W output with a 24VDC output voltage and a rated current of 4.17A. It uses a constant-power design and provides a constant-voltage output channel.

What dimming and color temperature range does this driver offer?

The LM-100-24-G2D2 supports dimming from 0% to 100%, with a maximum dimming depth of 0.1%. Its tunable white capability is controlled via DALI DT8 or Push DIM/CCT interfaces, allowing for adjustable color temperature in compatible systems.

Is this LED driver suitable for indoor commercial or architectural lighting?

Yes, this model is intended for indoor use and is described as suitable for indoor I/II/III type lamp applications. Its tunable white capability makes it relevant for commercial, architectural, and other indoor lighting projects where adjustable white light is required.

What operating conditions and protection features does this model have?

The specified operating temperature range is -20°C to 50°C. It includes over-heat, overload, and short-circuit protection with automatic recovery, and standby power loss is listed at less than 0.5W.

How does the LM-100-24-G2D2 differ from a standard non-tunable 24V LED driver?

The LM-100-24-G2D2 is built specifically for tunable white applications, not just basic 24V constant-voltage output. In addition to power delivery, it supports DALI DT8 control for dimming and color temperature adjustment via Push DIM/CCT interfaces.

What warranty is offered for the LM-100-24-G2D2?

The LM-100-24-G2D2 is a reliable option for indoor tunable white lighting systems. It features robust protection mechanisms including over-heat, over-voltage, over-load, and short-circuit protection with automatic recovery.
