AC 220V TO DC 12V 3A Transformer Power Supply

36W Power Output: Efficiently steps down grid power to deliver a steady, regulated 12V DC output up to 3A (36W max), providing clean power for compact 12V DC equipment.

AC 220V Grid Input Compatibility: Works seamlessly with standard 220V AC (180V–240V) 50/60Hz grid power with minimal standby loss and reliable energy conversion.

Fine-Tuning Voltage Trim: Integrated adjustment potentiometer (V_ADJ) allows fine-tuning of output voltage (-+ 10%, approx. 10.8V – 13.2V) to offset line resistance over long cable runs.

Silent Convection Air Cooling: Features a perforated aluminum mesh enclosure designed for natural air dissipation, providing silent, fan-free continuous operation.

Protected Terminal Connectors: Sturdy screw-terminal block with a transparent protective insulation cover guards against accidental contact and shorts.

Built-in Circuit Safeguards: Integrated safety features shield connected devices from output short circuits, continuous current overloads, over-voltage spikes, and overheating.

Housing & Casing Style: Vented aluminum alloy casing designed for efficient passive heat dissipation and electromagnetic interference (EMI) shielding.

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

Technical Specifications:

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

Output Voltage: DC 12V (Adjustable -+ 10%).

Output Current: 0A –3A Max.

Rated Power: 36W.

Cooling: Passive air convection via perforated casing.

Color: Silver metallic casing with yellow terminal marker.

Usage Advice: For continuous operational setups, size total connected loads to 80% of total rated capacity (2.4A / 28.8W). Verify phase (L), neutral (N), and ground (FG) terminals before applying main grid power.

Maintenance: Ensure the mesh enclosure is kept free of dust accumulation or metallic particles. Designed for indoor use; keep away from water spray and high moisture environments.

Essential 36W Power Hub: Position as a versatile intermediate power supply for LED lighting strips, multi-camera CCTV security hubs, access control systems, and DIY microcontroller workbenches.

Highlight Compact Size & Fan-less Design: Emphasize its silent, fan-free convection operation and small form factor that easily fits inside slim electrical junction boxes and equipment racks.
