AC 220V TO DC 12V 20A Transformer Power Supply

240W High-Capacity Power Output: Efficiently converts mains AC power into a regulated, stable 12V DC output up to 20A (240W max), providing heavy-duty current delivery for high-demand DC applications.

AC 220V Grid Input Compatibility: Designed for standard 220V AC (180V–240V) 50/60Hz grid input, ensuring low power ripple and high energy conversion efficiency.

Active Cooling Fan System: Equipped with an integrated low-noise DC cooling fan and vented aluminum alloy body to ensure optimal heat control under high operational loads.

Fine-Tuning Voltage Trim: Onboard adjustment potentiometer knob (V_ADJ) allows precision tuning of the 12V rail (-+ 10%, approx. 10.8V–13.2V) to compensate for voltage drops along long wire runs.

Multi-Terminal Bus Block: Heavy-duty screw terminals with a protective transparent flip cover support multi-channel parallel wiring configurations.

Comprehensive Protective Suite: Built-in automatic protection safeguards connected components against short circuits, continuous over-current, over-voltage spikes, and internal thermal conditions.

Housing & Casing Style: Industrial-grade vented aluminum alloy chassis designed for maximum thermal dissipation and structural protection against electromagnetic interference (EMI).

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

Technical Specifications:

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

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

Output Current: 0A – 20A Max.

Rated Power: 240W.

Cooling: Active internal cooling fan.

Color: Silver metallic casing.

Usage Advice: For continuous operation, size total loads to 80% of maximum rated capacity (16A / 192W). Always confirm proper Earth Ground (FG), Live (L), and Neutral (N) wiring before energizing power.

Maintenance: Ensure the fan intake and perforated side vents remain clean and free of dust or metallic shavings. Indoor switch-mode power supply; keep away from water spray and high moisture environments.

Essential High-Current 12V Workhorse: Position as a top-tier power supply for high-density 12V LED strip setups, multi-axis 3D printers, CCTV security camera power banks, and high-wattage electronics benches.

Highlight 240W Capacity & Active Fan Cooling: Emphasize the impressive 20A output rating paired with active fan cooling that prevents overheating during extended high-draw operation.
