AC 220V TO 150W DC 12V 12.5A Transformer Power Supply

Continuous 150W Power Delivery: Converts household AC grid power into a regulated, stable 12V DC output up to 12.5A (150W max) to cleanly drive medium-to-high wattage loads.

AC 220V Grid Input Compatibility: Engineered for standard 220V AC (180V–240V) 50/60Hz input systems with high energy efficiency and low ripple voltage.

Fine-Tuning Output Voltage Trim: Built-in adjustable potentiometer (V_ADJ) allows fine-tuning of the output voltage rail (-+ 10% approx. 10.8V–13.2V) to compensate for voltage drops over extended wire runs.

Passive Heat Dissipation Mesh: High-ventilation metal mesh enclosure provides natural air convection cooling to maintain thermal performance without noisy fans.

Protected Screw Terminal Block: Heavy-duty nickel-plated screw terminal connectors featuring a clear plastic insulation shield for safe multi-lead wiring.

Comprehensive Protective Circuitry: Onboard safeguards protect connected electronics against short circuit, continuous overload, over-voltage, and thermal conditions.

Housing & Casing Style: Vented aluminum alloy casing offering effective electromagnetic interference (EMI) protection and structural rigidity.

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

Technical Specifications:

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

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

Output Current: 0A–12.5A Max.

Rated Power: 150W.

Cooling: Passive air convection via perforated aluminum enclosure.

Color: Silver metallic casing.

Usage Advice: For continuous operational duty, calculate loads at 80% of maximum rated capacity (10A / 120W). Verify Live (L), Neutral (N), and Earth Ground (FG) terminals before applying main grid power.

Maintenance: Ensure the perforated enclosure remains clear of dust and metallic dust. Designed for indoor use; keep away from high humidity and direct water splash.

Essential 12V Mid-Range Power Hub: Position as an ideal power supply for mid-sized LED illumination installations, 12V CCTV security camera arrays, small CNC controllers, and 3D printer hotbed sub-assemblies.

Highlight Silent Operation & Reliable 12.5A Output: Emphasize the silent passive convection cooling paired with robust 12.5A current capabilities that bridge the gap between small adapters and fan-cooled supplies.

Recommended Cross-Sell Add-ons: Pair with AC 110V-220V to DC 12V 30A 360W Transformer Power Supply, S-150-12 DC12V 12.5A Slim Power Supply Transformer, AC 220V TO 360W DC 24V 15A Transformer Power Supply, and ESD antistatic mat 50x40CM PCB Welding Mat.
