LED Power Supply – 5V 20A 100W for Addressable LEDs

LED Power Supply 5V 20A 100W For Addressable Pixel LED Strips

The 5V 20A 100W LED power supply is purpose-built to drive addressable (pixel) LED strips and matrices based on ICs including WS2812B, SK6812, WS2815, APA102, and similar 5-volt digital LED technologies. Addressable LEDs require a stable, low-ripple 5VDC supply because voltage fluctuations directly manifest as flickering, colour shifting, or data communication errors in the LED pixel chain. This driver is engineered with tight voltage regulation (within +/-2%) and low output noise to ensure clean, consistent power delivery that keeps pixel animations smooth and colour-accurate across the full strip length.

At 100 watts (5V / 20A), this power supply can drive approximately 3.3 metres of WS2812B strip at 60 LEDs/metre running full white (approximately 18W/m at peak). For typical animated content where not all pixels run at maximum simultaneously, the practical capacity extends further. The unit features a ventilated metal chassis with thermal management for continuous duty in commercial installations, signage, and entertainment lighting. Multiple output terminal pairs allow parallel connection of several strip segments from a single driver, simplifying wiring in large pixel LED walls and perimeter installations.

BluxLED supplies this 5V 100W addressable LED power supply to signage manufacturers, event lighting companies, and LED pixel strip distributors worldwide. We stock standard models for fast dispatch and offer OEM configurations for high-volume orders. All units carry CE and RoHS certifications. If you supply WS2812B, SK6812, or similar addressable LED products and need a reliable 5V power source, contact our wholesale team for value and availability.

Frequently Asked Questions

What addressable LED strips are compatible with this 5V 100W power supply?

This driver is compatible with all 5V addressable LED strips using ICs including WS2812B, SK6812, WS2811 (5V variant), APA102, SK9822, and similar digital LED protocols. It provides the stable 5VDC these ICs require for both pixel data communication and LED colour output.

How many metres of WS2812B strip can this 5V 20A driver power?

WS2812B at 60 LEDs/metre draws up to approximately 18W/m at full white. At 100W capacity, this driver can power approximately 3.3 metres at full load. We recommend loading to 80% (80W) for continuous operation, giving approximately 2.6 metres. For longer runs, use multiple drivers with one driver per segment, or consider our higher-wattage 5V models.

Why do addressable LEDs need a special power supply versus standard LED strips?

Addressable LEDs contain driver ICs that process digital data signals alongside power. Voltage fluctuations, ripple, or noise on the power supply can corrupt data transmission between pixels, causing flickering, colour errors, or dead pixels. This 5V driver is specifically engineered with tight regulation and low ripple output to prevent these issues.

Can I use this 5V driver to power standard 12V LED strips?

No. This driver outputs 5VDC and is not compatible with 12V LED strips. Using a 5V supply on 12V strips will result in very dim or non-functional LEDs. Similarly, do not connect 5V addressable LED strips to a 12V driver, as this will destroy the LED ICs instantly. Always match the driver output voltage to the LED strip specification.

How should I wire multiple LED strip segments to this driver?

Use the dual parallel output terminals to connect multiple strip segments. Each segment should have its own positive and negative connections back to the driver terminals (star wiring topology). Avoid daisy-chaining power through the LED strip’s copper traces for more than 1-2 metres, as voltage drop along the strip can cause colour inconsistency at the far end.

What wire gauge is recommended for 5V 20A output connections?

At 20A, we recommend a minimum of 2.5mm² (14 AWG) for the main power connections from the driver to a distribution point. For individual strip segment connections, 1.5mm² (16 AWG) is adequate for runs up to 1 metre. Keep output cable lengths as short as possible to minimise voltage drop, which is more critical at 5V than at higher voltages.

Is this driver suitable for continuous operation in signage installations?

Yes. This driver is rated for continuous duty with a ventilated metal chassis and temperature-controlled cooling fan. The metal housing and active thermal management make it suitable for 24/7 operation in signage, display, and commercial lighting installations. We recommend installing the driver in a ventilated position and loading to 80% for maximum lifespan in continuous-use applications.
