LCA 25W LED DRIVER TRIDONIC

LCA 25W LED DRIVER TRIDONIC – Premium Dimmable Constant Current Power Supply

The LCA 25W LED DRIVER TRIDONIC (Tridonic Premium Series / one4all SC PRE) is an industrial-grade, dimmable constant current LED driver engineered for commercial, architectural, and high-end residential lighting systems. Offering a maximum power output of 25 W, this versatile power supply operates within a flexible adjustable output current window ranging from 350 mA to 1,050 mA.

Equipped with Tridonic’s multi-protocol one4all interface, the LCA 25W LED DRIVER TRIDONIC seamlessly integrates with DALI/DALI-2 (DT6), DSI, switchDIM, and corridorFUNCTION protocols. Furthermore, it supports wireless or mains-based configuration through ready2mains programming and plug-in I-SELECT 2 resistors. Designed with energy savings in mind, it provides smooth digital dimming down to 1% with low standby losses.

As illustrated in the product image, the unit features a durable white flame-retardant polycarbonate housing with integrated push-in terminal blocks color-coded for quick tool-free wiring (Line, Neutral, DALI/Switch control, and DC LED outputs).

Key Features of the LCA 25W LED DRIVER TRIDONIC

• Multi-Protocol Control (one4all Interface): Fully compatible with DALI-2, DSI, switchDIM (push-button dimming), and corridorFUNCTION automated sensor integration.

• Wide Adjustable Output Current (350 mA – 1,050 mA): Precise output current adjustment in 1 mA steps using DALI commands, ready2mains programmer, or I-SELECT 2 resistor plugs.

• Ultra-Smooth 1–100% Dimming: High-resolution digital dimming window down to 1% with flicker-free operation across all light levels.

• lumDATA & Smart Analytics: Meets DALI-2 parts 251 (Luminaire Data), 252 (Energy Reporting), and 253 (Diagnostics & Maintenance) for smart building energy monitoring.

• Constant Light Output (CLO): Automatically compensates for LED lumen depreciation over time to maintain steady room illumination throughout the fixture’s lifespan.

• Tool-Free Installation: Features convenient 45° push-in spring terminals for fast and secure conductor connections without requiring screwdrivers.

• Built-In Electronic Protection: Includes comprehensive protection against overtemperature, short circuits, open circuits/no-load, and input line overvoltage.

Common Applications and Practical Usage

The versatility and compact form factor of the LCA 25W LED DRIVER TRIDONIC make it an ideal choice for high-performance luminaire integration:

• Downlights & Architectural Spotlights: Provides flicker-free dimming and steady current control for retail and hospitality recessed lighting setups.

• Commercial Office Linear Lighting: Powers troffers, suspended linear LED channels, and architectural fixtures requiring intelligent DALI-2 central control.

• Emergency Escape Lighting: Fully compliant with EN 50172 emergency power supply systems, providing immediate switchover capability to DC operation.

• Smart Building Networks: Enables centralized energy metering, preventive maintenance logging, and daylight harvesting automation.

Installation Guidelines and Best Practices

SAFETY NOTE: Disconnect mains power supply prior to wiring. The driver must be installed inside an enclosure or luminaire housing providing IP20 or higher protection.

• Current Setting: Set the target LED drive current (350 mA – 1,050 mA) via the ready2mains software or insert the appropriate I-SELECT 2 resistor plug into the designated slot before connecting the LED module.

• Terminal Conductor Preparation: Use solid or stranded wire leads (0.2 to 1.5 mm2) stripped to 8.5 –9.5 mm for optimal insertion into the spring-loaded push terminals.
