QLT 8,4W 18V 500mA Driver PLJ204 Power Supply IP65 for 1-4 LED modules

The QLT PLJ204 power supply is a compact and reliable constant current LED driver designed by QLT to power high-performance LED systems. Built in PVC and resin, this built-in converter delivers a constant current output of 500mA (±10%) at an output power of 8.4W at 18V, providing stable and continuous power supply for 1 to 4 LED modules. Its compact footprint — 53 mm in diameter and just 19 mm deep — makes it easy to integrate even into the most space-constrained installations.

The IP65 protection rating makes the PLJ204 especially suited for installations in humid or dusty environments, where waterproof performance is an essential requirement. The universal input voltage range of 100–240V AC ensures full compatibility with all major international electrical standards (EU, AUS, USA, UK, JAP), while insulation class II provides an additional layer of electrical safety by removing the need for grounding. The unit also features self-resetting protection against overtemperature, open circuit and output short circuits.
