What does an LED driver do?
LED strip runs on low-voltage DC, so it needs a driver to convert mains (200–240V AC) into a stable 12V DC supply. The LP-50-12 is a constant voltage driver designed for 12V LED strip. Choose a driver with around 20% spare capacity for a long, reliable life.

Installation
Mains wiring should be carried out by a qualified electrician. Install the driver in a dry, ventilated location – not in insulation or sealed voids. Keep the low-voltage cable run to the strip as short as practical and size the cable for the current (0.5mm² up to 3A · 0.75mm² up to 6A · 1.0mm² up to 8A).
Frequently asked questions
How many metres of LED strip can a 50W driver power?
At 80% load it powers up to 5.5m of 7.2W/m strip, or 2.7m of 14.4W/m strip. Multiply the strip length by its watts per metre and keep the total below 40W.
Can I use it with 12V and 24V strip?
No. This is a 12V driver and must only be used with 12V LED strip. Using the wrong voltage will damage the strip or give very dim light.
Can I dim LED strip with this driver?
This driver is not TRIAC dimmable. To dim, add a smart controller between the driver and the strip, or choose one of our TRIAC dimmable drivers.
Can I install it outdoors?
No. It is designed for indoor, dry locations. For outdoor use choose one of our IP66 TRIAC dimmable drivers.
Can I connect several strips to one driver?
Yes, as long as the total wattage of all the strips stays below 80% of the driver's rating. Wire each strip back to the driver rather than daisy-chaining long runs.
