120W 12V LED Power Supply Driver 10A with US Standard 3-Prong Plug - AC 100-260V to 12V DC Constant Voltage Transformer, IP67 Waterproof

120W 12V LED Power Supply Transformer (10A, IP67 Waterproof)

Key Features

• Constant Voltage Output: Delivers a stable 12V DC output suitable for LED lighting and sensitive electronics.
• High Power Capacity: Rated for 10 Amps and 120 Watts maximum load.
• IP67 Waterproof Rating: Fully sealed aluminum housing protects internal components from dust ingress and temporary immersion in water.
• Universal AC Input: Accepts a wide input voltage range of 100V-260V AC (50/60Hz).
• Safety Protection: Built-in automatic protection against short circuits, over-load, over-voltage, and over-temperature.
• Passive Cooling: Fanless design operates silently and relies on the metal chassis for heat dissipation.
• Standard Connectivity: Includes a pre-wired US standard 3-prong grounded plug for AC input and bare wire leads for DC output.

Replaces / Cross-Reference

This unit serves as a universal replacement for 12V DC constant voltage drivers meeting the following criteria:

• Replaces drivers rated 12V DC with amperage of 10A or lower (e.g., 1A, 2A, 5A, 8A).
• Replaces non-waterproof adapters when upgrading for outdoor or damp environment use.
• Compatible replacement for generic LED transformers marked "Constant Voltage."
• Standard replacement for failed OEM drivers in commercial signage and landscape lighting systems requiring 12V DC.

Compatibility & Fitment

Designed for use with 12V DC devices. Common applications include:

• LED Strip Lights: Compatible with 5050, 3528, and COB LED strips.
• Outdoor Lighting: Suitable for garden lights, landscape path lighting, and deck lights requiring 12V.
• LED Modules: Powers signage modules and channel letters.
• CCTV Cameras: Fits security camera systems requiring 12V power.
• Cabinet Lighting: Under-cabinet bars and puck lights.
• Computer Accessories: Compatible with 12V DC computer fans and project components.

When to Replace

Replace your existing power supply if you observe the following:

• Flickering Lights: LEDs strobe or flicker, indicating voltage instability.
• Delayed Start: Lights take several seconds to turn on after the switch is flipped.
• Intermittent Power: The unit shuts off randomly due to overheating or failing internal components.
• Audible Noise: A loud buzzing or humming sound (coil whine) coming from the driver.
• Zero Output: Multi-meter reads 0V at the output leads despite receiving AC power.

Installation Tips

• Load Calculation: For continuous use, do not load the driver to 100% capacity. Adhere to the 80% rule: keep the total wattage of connected lights under 96W (80% of 120W) to extend the lifespan of the unit.
• Polarity: Observe correct polarity on the DC output side. Red is Positive (+), and Black is Negative (-). Reversing polarity can damage connected LEDs.
• Ventilation: Although the unit is waterproof, ensure it is mounted in an area with airflow to facilitate heat dissipation. Do not bury the unit in insulation or enclosed, air-tight spaces.
• Waterproof Connections: While the driver itself is IP67 rated, the connection points where the DC wires meet your lights must be sealed with waterproof wire nuts or shrink tubing if used outdoors.
• Input Power: Plug directly into a standard grounded outlet. Do not remove the ground prong.
