Original Press Release:

New Higher Power Additions to Economical Constant Current LED Power Supply Series

Aldermaston: Sunpower’s new PCD/PLD 40/60 series comprises 40 W and 60 W economical constant current LED power supplies with PFC; these products extend the well-established PCD/PLD-16/25 range. The PCD versions feature AC phase-cut dimming control which can be implemented using either leading edge or trailing edge TRIAC dimmers. The products fulfil AC dimming requirements for the LED lighting market.

The entire series features a 180-295 Vac input range; each of the series’ four families (PCD and PLD, 40 W and 60 W) comprise a number of products with different output current and voltage capabilities. Constant current single outputs from 350 mA to 2400 mA are available. With a high efficiency rating of up to 88%, these devices need only free air convection cooling for -30°C to +50°C ambient temperature operation. This makes the series suitable for either outdoor LED lighting or indoor decorative lighting applications.

Single-stage PFC topology allows the four products to economically meet the requirements of high power factor - greater than 0.9 – and EN61000-3-2 Class C (harmonic current) specifications for the lighting industry. With their Class ll no Frame Ground design and double insulation, they are enclosed within UL 94V-0 rated plastic cases; these are effective in protecting users from electric shock. User safety is further guaranteed by the new models’ compliance with ENEC EN61347-2-13 and EN62384 lighting certificates, while CE and IP30 ingress protection is also provided. Short-circuit and over temperature protection is built in.

“These new units make an attractive higher-power option for lighting system installers” said Andy Wall, CEO at Sunpower Technology LLP, “They’re competitively priced while their high reliability is underwritten with a three-year warranty. They’re convenient too, as the PCD-40/60 products have been successfully tested for compatibility with a wide range of well-known TRIAC dimmers.”
