How to connect a LED strip to a power supply?
To connect an LED strip to a power supply, you can use a solderless wire connector or solder a DC female connector to the LED strip. Ensure the power supply's output voltage matches the LED strip's working voltage (usually 12V or 24V). If the LED strip has a DC female connector, plug it into the corresponding DC male connector on the power supply. If the LED strip has open wires, you can hardwire them to the power supply or use solderless connectors.
What happens when an LED is directly connected to a power supply?
Directly connecting an LED to a power supply can cause damage to the LED. LEDs require a specific voltage and current to operate safely. Connecting an LED directly to a power supply without proper regulation can lead to overvoltage, which can burn out the LED. Additionally, the voltage from a standard power supply (e.g., 220V AC) is too high for most LEDs, which operate on low voltage DC (e.g., 12V or 24V).
How to connect LED driver to power supply?
To connect an LED driver (power supply) to a power source, ensure the AC power plug of the power adapter is inserted into a socket. For power supplies with open wires, use a screwdriver to loosen the screws, then insert the wires of the LED strip into the corresponding screw holes. Tighten the screws and pull the wires by hand to ensure a firm connection. For power supplies with DC connectors, simply plug the DC male connector of the power supply into the DC female connector of the LED strip.
What power supply do I need for LED strip lights?
To choose the right power supply for LED strip lights, ensure the output voltage of the power supply matches the working voltage of the LED strip (usually 12V or 24V). Calculate the total power required by multiplying the power of one meter of the LED strip by the total number of meters. Then, select a power supply that is at least 80% of the calculated total power to prevent overheating and extend the life of the power supply.
