AC 220V TO DC 5V 2A Transformer Power Supply

10W Power Output: Converts AC grid voltage into a regulated, stable 5V DC output up to 2A (10W max), serving as a reliable low-voltage power source for sensitive digital electronics.

AC 220V Grid Input Compatibility: Designed to accept standard 220V AC (180V–240V) 50/60Hz grid power with high power conversion efficiency and low standby loss.

Fine-Tuning Voltage Trim: Onboard adjustment potentiometer knob (V_ADJ) allows precise output calibration (-+ 10%, approx. 4.5V–5.5V) to offset line resistance loss over cable runs.

Silent Passive Convection Cooling: Perforated aluminum mesh casing facilitates continuous natural air movement for completely silent, fan-less operation.

Protected Terminal Connectors: Sturdy screw terminal connectors featuring a clear plastic insulation shield guard against accidental contact and shorts.

Integrated Safety Circuitry: Built-in automatic protection safeguards connected components against short circuits, continuous over-current, and over-voltage conditions.

Housing & Casing Style: Ultra-compact vented aluminum alloy casing designed for natural thermal radiation and electromagnetic interference (EMI) shielding.

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

Technical Specifications:

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

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

Output Current: 0A–2A Max.

Rated Power: 10W.

Cooling: Passive air convection via perforated casing.

Color: Silver metallic casing.

Usage Advice: For continuous operational duty, calculate total power draw at 80% of total rated capacity (1.6A / 8W). Always confirm Live (L), Neutral (N), and Earth Ground (FG) terminals before energizing.

Maintenance: Keep the perforated metal casing clean and free of dust or metallic particles. Designed for indoor use; keep away from high humidity and direct water splash.

Essential Compact 5V Driver: Position as an entry-level power supply for low-power 5V microcontrollers (ESP32, Arduino, Raspberry Pi Pico), small addressable LED segments, USB hubs, and relay boards.

Highlight Ultra-Compact Footprint & Silent Operation: Emphasize its small spatial footprint paired with fan-less, noiseless operation that makes it easy to integrate inside small control enclosures.
