Enhanced Design with Included Accessories
The power supply comes equipped with alligator clamp cables, copper wire, cable lugs, metal clips, screws, and a UL power cord, making installation quick and flexible. The nickel-plated copper terminals offer excellent conductivity, reduced resistance, and strong anti-corrosion performance—perfect for applications that need direct clamp connection.

Smart Safety & Protection System
Built-in intelligent protection safeguards the unit and connected devices under various load conditions, including:
- Overload protection
- Over-voltage protection
- Over-temperature shutoff
- Short-circuit protection
- EMI/RFI noise filter for stable output
Each power supply undergoes full-load burn-in testing to ensure performance consistency, low temperature rise, and long-term reliability.

Advanced Cooling & Durability
Designed with multiple heat-dissipation vents, a high-speed cooling fan, and an internal dust-resistant structure to maintain airflow and keep components clean. The rugged metal enclosure improves durability and protects internal circuits from heat damage, helping extend the overall service life of the unit.

Simple Operation & Dual Connection Options
A built-in power switch makes it easy to turn the output on or off safely. The integrated wiring layout and dual connection modes allow users to choose between:
- Screw terminal connections
- Clamp-style quick connections
This provides flexibility for both fixed installations and mobile 12V applications.

Adjustable Output for Multiple Load Requirements
Supports AC 110V / 220V input (85–145V and 185–265V tolerance). The output adjusts according to the connected load. Example reference values:
- 12V 10A ≈ 120W
- 12V 20A ≈ 240W
- 12V 35A ≈ 420W
- Peak output: 50A / 600W
For continuous use, the recommended load is ≤ 40A / 480W.
General sizing guidelines:
- For resistive loads: SMPS peak power ≥ device power × 1.25
- For motor loads: SMPS peak power ≥ device power × 2

Wide Application Range
This 12V power supply can be used for a wide variety of DC systems, including:
- Car stereos, amplifiers, radios
- 12V pumps, winches, air compressors
