Ltech M4+M4-3A Mini Controller with RF Remote - RGBW

The Ltech M4+M4-3A is an RGBW mini controller intended for LED lighting applications that need color adjustment and mode selection from an RF remote. It is positioned for standalone LED control where buyers want one compact controller for RGBW lighting effects. This model is suited to projects that need remote-based brightness and speed adjustment rather than basic on-off control.

This model accepts a 12~24V DC input and supports a maximum current load of 3A per channel (4 channels, max 12A total). The maximum output power ranges from 0~36W to 72W per channel depending on the input voltage. These figures define the controller's core operating capacity for RGBW LED control.

This controller uses RF dimming control. The M series receiver is compatible with 8 kinds of remotes with different functions. That makes this model a fit for buyers specifically looking for RF-based RGBW control rather than a controller described with another control method.

This model is built for RGBW adjustment, not just single-color dimming. The description highlights color customization plus lighting mode, speed, and brightness adjustment through the RF remote. Buyers choosing between simple dimming and multi-channel color control would typically look at this model for the added RGBW flexibility.

The published operating temperature range is -30°C to 55°C. That gives buyers a clear reference for whether the controller matches the environmental conditions of their planned installation. The product carries FCC, CE, RoHS, and ISO9001:2008 certifications, which is useful for longer-term commercial or project-based purchasing decisions.
