Overview
The 70W High-Output Linear LED Module PCBA (900mm Series) is an ultra-long light engine designed for 3-foot (900mm) and multi-foot continuous commercial luminaires. Measuring 900mm × 20mm × 2.0mm, this rigid aluminum board incorporates 160 pieces of premium Samsung 561C LEDs configured in a 16-series / 10-parallel (16S10P) topology. Operating at 70W nominal power (48V DC forward voltage at 1460mA), it features a heavy 2oz copper foil and 2.0 W/m·K thermal dielectric substrate for rapid thermal spreading. Integrated with 2pcs original Wago 2060-402/998-404 double-pin SMD connectors (providing 2 positive and 2 negative poles), it enables high-current carrying capacity and effortless, solderless wiring.

Key Technical Advantages
High-Density 160pcs Samsung 561C Matrix: Features 160 high-efficiency Samsung 561C (S6 bin) SMD diodes spread over a 900mm length, delivering 70W of powerful, shadowless, and uniform continuous linear lighting.
Industry-Standard 48V DC Architecture: Designed around a standard 48V DC system voltage at 1460mA, making it 100% compatible with mainstream Class 2 / SELV 48V constant-voltage or constant-current LED power supplies.
Authentic Wago 2060 Push-In Connectors: Surface-mounted with 2pcs Wago 2060-402/998-404 double-pin push-button terminals (2-in positive, 2-in negative). Supports push-button wire insertion and removal for automated line assembly and high-current (up to 9A rated) reliability.
Heavy-Duty 2.0mm Board & 2oz Copper: Utilizes an extra-stiff 2.0mm thick aluminum substrate backed by 2oz heavy copper foil and a 2.0 W/m·K thermal dielectric layer to eliminate board bending while rapidly dissipating junction heat (Tj).
Modular 900mm (3-Foot) Form Factor: Perfect standalone board for 3ft fixtures, or combined to build 6ft (1800mm) and 9ft (2700mm) continuous linear architectural trunking systems.
Applications & Fixture Compatibility
Commercial & Architectural Lighting: 3-foot, 6-foot, and continuous-run linear pendant lights, slot fixtures, and recessed office troffers.
Industrial & Supermarket Illumination: High-lumen trunking light systems, warehouse linear bays, and retail shelf illumination.
Custom OEM/ODM Luminaire Engineering: Standard light engine module for luminaire manufacturers designing low-profile, high-wattage 48V linear illumination systems.
Frequently Asked Questions (FAQ)
Q1: What power supply parameters are required for this 70W 900mm LED module? A: This module requires a constant current driver (or 48V system driver) providing 1460mA at a nominal forward voltage of 48V DC (rated at 70W output per board).
Q2: What are the advantages of using Wago 2060-402 connectors on this board? A: The integrated Wago 2060-402 SMD terminals feature push-button technology that accepts both solid and fine-stranded conductors without manual soldering. With 2 positive and 2 negative poles, they allow easy parallel feed-through wiring between modules in continuous linear runs.
Q3: Is the 900mm length prone to thermal expansion or mechanical bending? A: No. The board uses a thick 2.0mm aluminum substrate (weight approx. 105g) combined with 2oz copper and a 2.0 W/m·K dielectric layer, ensuring high mechanical rigidity and uniform heat distribution across the entire 900mm span.
