AC 220V TO 100W DC 5V 20A Transformer Power Supply

High Output 100W 5V Power Supply: Converts household AC grid power into a continuous, regulated 5V DC output up to 20A (100W max), ideal for driving high-density 5V digital circuitry and lighting arrays.

AC 220V Input Compatibility: Designed to step down standard 220V AC (180V–240V) grid power with high power conversion efficiency and minimal standby loss.

High-Density 5V Amperage Output: Delivers clean, stable current to prevent voltage drops across extensive addressable RGB LED strips, matrix panels, microcontrollers, and relay banks.

Fine-Tuning Voltage Potentiometer: Onboard voltage trim adjustment ($V_{\text{ADJ}}$) allows precise calibration of the 5V rail ($\pm 10\%$, approx. $4.5\text{V}\text{–}5.5\text{V}$) to compensate for cable resistance on long wire runs.

Heavy-Duty Screw Terminal Block: Multi-point screw output terminals with a protective transparent flip guard allow secure wiring for multiple parallel load branches.

Comprehensive Multi-Protection Suite: Built-in automatic protection safeguards against short circuits, output over-current, over-voltage, and thermal overload conditions.

Housing & Casing Style: Industrial-grade perforated aluminum alloy casing engineered for passive convection cooling and effective EMI shielding.

Contact & Terminal Style: Nickel-plated screw terminal connectors (L, N, FG, -V, -V, +V, +V).

Technical Specifications:

Input Voltage: AC 220V -+ 15% (50/60Hz).

Output Voltage: DC 5V (Adjustable -+ 10%).

Output Current: 0A–20A Max.

Rated Power: 100W.

Cooling: Passive air convection via mesh casing.

Color: Silver metallic casing.

Usage Advice: Ensure total continuous power load does not exceed 80% of rated capacity (16A / 80W) for optimal lifespan. Verify line input phase (L), neutral (N), and ground (FG) connections before applying power.

Maintenance: Keep the perforated aluminum mesh clean and free of dust or metal shavings. Indoor switch-mode power supply; keep away from moisture and water spray.

Essential High-Current 5V Driver: Position as the core power supply for extensive WS2812B/SK6812 addressable LED strip arrays, WS2811 pixel displays, multi-node MCU setups, and 5V smart home control hubs.

Highlight High-Amperage 5V Capacity & Solid Construction: Emphasize the high 20A current rating that eliminates voltage sag in large-scale low-voltage electronics and ambient lighting projects.
