SLD & LDC Series Professional LED Drivers

MEAN WELL SLD and LDC series are high-performance LED drivers designed for professional commercial and architectural lighting. They combine ultra-slim profiles, DALI-2/IoT connectivity, and robust constant power output capabilities.

SLD Series: Features an ultra-slim, built-in design, perfect for sleek architectural luminaires and track lighting where internal space is highly restricted.
LDC Series: High-performance Constant Power (CP) drivers capable of maintaining full wattage across a broad range of output currents, greatly simplifying lighting fixture design.

Key Features

Flicker-Free Output: Provides high-frequency, stable current to ensure visual comfort in commercial and office environments.
Multi-Protocol Support: Equipped with DALI-2, Push Dim, and IoT (Bluetooth/Wireless) interfaces to meet modern building automation demands.
Auxiliary Power: Built-in auxiliary DC output (e.g., 12V/50mA) to power environment sensors, cooling fans, or smart control modules.
Comprehensive Protection: Equipped with short-circuit, over-voltage, and over-temperature protection for long-term reliability.

SLD vs. LDC Comparison

Series	Core Characteristic	Form Factor	Recommended Application
SLD	Ultra-Slim	Extra-thin casing	Architectural lighting, track lights, linear luminaires.
LDC	Constant Power	Standard linear	Commercial general lighting, panel lights, troffers.

Selection Tip: If your luminaire has extremely restricted height, choose the SLD series. If you require a constant power driver that allows for flexible current settings to match various LED configurations, the LDC series is the ideal choice.

Smart Control & Dimming

These series are at the forefront of the IoT lighting transformation, supporting advanced digital control standards:

Protocol	Key Functionality
DALI-2 / Push Dim	Supports DALI-2 complex office networks and simple Push Dimming via standard mechanical switches.
IoT Wireless	Supports Bluetooth Mesh (Casambi/Tuya/Silvair) ecosystems for App-based dimming and wireless commissioning.
NFC Programming	LDC series supports NFC wireless current settings, allowing precise configuration via smartphone App without physical DIP switches.
