Deliver robust, stable, and silent power to your most demanding lighting applications with the Meanwell UHP-1000-12, a professional-grade 1000W 12 volt DC power supply. As part of Meanwell's premium UHP series, this unit stands apart from standard power supplies with its innovative fanless design, relying on efficient conduction cooling for completely silent operation. This makes it the ultimate choice for noise-sensitive environments like recording studios, theaters, and high-end residential installations. Featuring active Power Factor Correction (PFC) for superior efficiency and a UL-listed certification for guaranteed safety, the UHP-1000-12 is the definitive high-wattage solution for large-scale LED strip projects, industrial controls, and any application requiring a reliable 12 volt dc power supply for led lights.


Provides a steady 12V DC at up to 83.3A, perfect for powering extensive LED arrays and heavy-duty equipment.
Utilizes advanced conduction cooling to dissipate heat without a fan, ensuring zero noise and enhanced reliability with no moving parts.
Built-in active Power Factor Correction (>0.95) improves energy efficiency, reduces electricity costs, and minimizes harmonic distortion.
Rigorously tested and certified by UL, ensuring compliance with the highest safety standards for professional and commercial use.
Supports a full range of AC inputs, with selectable plug options for 110V (US/CA) and 220V (EU/UK/AU) regions.
Features built-in safeguards against short circuits, overload, over-voltage, and over-temperature to protect your connected devices.

Q: What is the main advantage of a fanless power supply?
A:A fanless design means silent operation and higher reliability. With no moving parts like a fan, there is one less component that can fail, making it ideal for long-term installations and noise-sensitive areas.
Q: How many feet of LED strips can this 1000W power supply run?
A:This depends on the wattage per foot of your LED strip. As a rule, your total load should not exceed 800W. For a strip that uses 5W/ft, you could safely power up to 160 feet (800W / 5W/ft).
Q: Is this power supply dimmable?
A:This power supply itself is not dimmable. To dim 12V LED strips connected to it, you would need to install a separate PWM dimmer between the power supply's DC output and the LED strips.
Q: What is the difference between the UHP-1000-12 and other Meanwell power supplies like the LRS series?
A:The UHP series is a premium line designed for high performance and silent, fanless operation via conduction cooling. The LRS and NES series are general-purpose power supplies that typically use fans for cooling at this high wattage.
Q: Does this power supply come with an on/off switch?
A:The power supply unit itself does not have an integrated on/off switch. Power is controlled by the AC source it's connected to, such as a wall switch or a switched power cord.
Q: Can I use this power supply outdoors?
A:No, the UHP-1000-12 has an IP20 rating, which means it is designed for indoor use in dry locations only and is not protected against moisture or water.
Q: Is an AC power cord included?
A:You can choose to purchase the power supply alone or as a kit with a compatible AC power plug for your region. Please select the desired option before adding to your cart.
