Application Scenarios
How to Wire & Install This Power Supply
- Step 1: Verify Voltage Compatibility. Ensure the device or LED lighting you are powering requires 12V DC. Mismatching voltage can permanently damage your equipment.
- Step 2: Calculate Load. For optimal performance and longevity, do not exceed 80% of the power supply's capacity. Your total load should be 800W or less. See our guide to calculate power for LED strip lights.
- Step 3: Wire AC Input. Safely connect your AC source wires to the input screw terminals: Line to (L), Neutral to (N), and a protective Earth ground to (FG).
- Step 4: Wire DC Output. Connect the wires from your LED load to the DC output terminals. Ensure correct polarity: Positive wire to (V+) and Negative wire to (V-). Reversing polarity can damage your LEDs.
- Step 5: Ensure Proper Mounting. For effective conduction cooling, the power supply must be securely mounted to a flat metal surface, like a chassis or mounting plate, to dissipate heat.
- Step 6: Power On & Test. Once all connections are secure, apply AC power and confirm that your lights or device operate as expected.
- Installation should be performed by a qualified electrician in accordance with local codes.
- This is not a constant current driver. It provides a constant 12V voltage.
- This unit is IP20 rated and must be installed in a dry, indoor location, protected from moisture and dust.
- Allow for adequate ventilation around the unit. Do not operate in a fully enclosed, unventilated space.

Frequently Asked Questions
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.
