LTECH SE-40-300-1050-W2MA 40W Matter Tunable White Constant Current LED Driver

300–1050mA Matter over Thread Tunable White Driver with NFC Programming and Ultra-Deep Dimming

The LTECH SE-40-300-1050-W2MA is a compact 40W constant-current smart LED driver designed for professional tunable white lighting applications. With an adjustable output current from 300mA to 1050mA, a 9–42V DC output range and up to 40W output power, it provides flexible compatibility with a wide range of two-channel warm white and cool white LED modules.

Featuring Matter over Thread connectivity, the driver provides intelligent control of both brightness and colour temperature through compatible smart home ecosystems including Apple Home, Google Home, Amazon Alexa and Samsung SmartThings. The tunable white range can be configured from 1000K to 10000K, with a default range of 2700K to 6500K, making it suitable for applications requiring flexible warm-to-cool white lighting control.

LTECH T-PWM ultra-deep dimming technology provides smooth 0–100% brightness adjustment with dimming depth configurable down to 0.0001%. Integrated NFC programming allows the output current to be adjusted in precise 1mA steps using the LTECH NFC Lighting app, while parameters including dimming fade time, power-on fade time, brightness range, colour temperature range and power-on status can also be configured.

Operating from a wide 100–240V AC or 120–250V DC input, the SE-40-300-1050-W2MA provides up to 88% typical efficiency and features a V0 flame-retardant PC housing with tool-free screwless end covers. Overheat, over-voltage, overload and short-circuit protection with automatic recovery are built in, while network standby and no-load consumption below 0.5W, a service life of up to 100,000 hours and a 5-year manufacturer warranty make it a dependable solution for Matter-controlled tunable white lighting systems.
