FAQ

What is the Ltech LM-75-24-G2M2 designed for?

The LM-75-24-G2M2 is a 75W constant-voltage 24VDC LED driver for lighting applications that need DMX dimming and tunable white control. It provides two independently SELV constant-voltage output channels and is intended for indoor Class I, II, and III lamp applications.

What dimming control does this LED driver support?

This model supports DMX512/RDM dimming control and also lists Push DIM/CCT capability. It offers dimming from 0-100% and supports very low-end output, with a dimming depth of max. 0.1%.

Is the LM-75-24-G2M2 suitable for tunable white or color temperature adjustment?

Yes. This driver is built for color temperature adjustment from 2700K to 6500K while using a constant power design to help keep brightness consistent during CCT changes. That makes it a fit for tunable white LED lighting applications using two output channels.

What are the main electrical ratings of the LM-75-24-G2M2?

The LM-75-24-G2M2 is rated at 75W output power with a 24VDC output. Its rated current is 3.125A, which aligns with its constant-voltage LED driver design for 24V lighting systems.

Does this model support RDM functionality?

Yes. This driver supports the RDM remote device management protocol in addition to DMX512 control. That can be useful in projects where remote device management is part of the control environment.

Can the LM-75-24-G2M2 be used in demanding indoor environments?

It is specified for indoor applications and has an operating temperature range of -20°C to 50°C. The unit includes protections for short circuit, over-heat, over-load, and over-voltage conditions.

How does this model differ from a standard non-DMX 24V LED driver?

Compared with a basic 24V constant-voltage driver, the LM-75-24-G2M2 adds DMX512/RDM dimming, Push DIM/CCT support, and two independently SELV output channels for tunable white applications. It is positioned for projects that need more advanced lighting control rather than simple fixed-output power.

What warranty is offered for the LM-75-24-G2M2?

This model includes a 5-year warranty. The description also notes Rubycon capacitor use as part of that warranty positioning.
