AC-DC converter for LED lighting applications

11 June 2008 Power Electronics / Power Management

Mean Well has released a new 150 W AC-DC converter for the growing demands of large scale LED lighting related applications. With a wide input range from 90-280 V a.c., the CLG-150 series also features an active PFC function complying with EN61000-3-2 (harmonic current) class C for greater than 50% of output rated loading that fulfils the requirement of typical lighting applications.

A key feature is the user adjustable output voltage and current level. Maintaining IP65/67 protection level against dust and moisture, users still can adjust these settings by removing the rubber stopper on the case or through the output signal cable - functionality which is often requested by LED system integrators.

The efficiency of the converters is as high as 90%, allowing them to operate between -30 and +70°C with air convection alone. Standard functions include short circuit, overload, over-voltage, and over-temperature protection.

Typical applications include general outdoor usage, LED streetlamps, mid-scale moving signs and backlighting, LED-based decorative/architectural lighting, LED stage and theatre lighting, and LED electronic displays.
