Taitong DR40S LED Driver
For domestic and commercial installations that need scene control and independent luminaire control. The driver is compact, dims smoothly and supports deep dimming with fine step values. Its twin-cable output suits small, low-voltage luminaires. Communication is over Bluetooth — no signal wiring or complex addressing — so configuration is straightforward. The device connects directly to the phone app or works alongside other Bluetooth devices, supporting single-device, group and scene-cluster control. Third-party light sources are supported — when using them, make sure the driver output voltage and current match the luminaire.
