18V 55W Power Supply for LED Strips and Surveillance Cameras
Compact transformer in a perforated metal casing, designed for stable power supply to LED strips, surveillance cameras, and other devices requiring 18V DC. It connects directly to the 220V mains and provides a constant current of up to 3A, with overload protection and a passive cooling system through the metal casing.
What you get with this product
- Stable power supply without voltage fluctuations — protects LED and electronic equipment from mains variations
- Perforated metal casing — efficient heat dissipation for continuous operation without overheating
- Adjustable voltage between 17V and 19V DC — precisely adapt the power supply to the requirements of connected devices
- Compatible with LED strips, surveillance cameras, spotlights, and panels — universal solution for lighting and security projects
- Compact dimensions 110 x 80 x 37 mm — easily mounted in small spaces, technical cabinets, or distribution boards
- Simple connection via labeled terminal blocks — quick wiring without risk of polarity reversal
How it works and how to install it
The power supply converts the 220V AC voltage from the socket to stable 18V DC for your devices. You connect the power cable to the L-N-M terminals, check that the voltage selector is set to 220V, then connect the LED devices or camera to the V+ and V- terminals. If you need fine adjustment, turn the ADJ potentiometer to adjust between 17V and 19V. Install the power supply in well-ventilated areas, away from humidity, without covering the perforations of the casing to allow natural cooling.
Frequently Asked Questions
Can I connect multiple LED strips to this power supply?
Yes, provided that the total power of the strips does not exceed 55W and the total current does not exceed 3A. Calculate the total consumption before connecting.
Is it suitable for outdoor use or wet locations?
No, the power supply has an IP20 protection rating and is intended exclusively for indoor mounting, in dry and ventilated areas, away from splashes or direct contact with water.
How do I know if the power supply is working correctly?
After connecting to the mains, use a multimeter to check that the output voltage is 18V DC. If the connected devices are working normally and the casing does not overheat, the power supply is operating correctly.
