Sunpower adds two constant current LED power supplies

The PCD/PLD 40/60 40 and 60W economical, constant current LED power supplies have been introduced by the company.

The PCD versions feature AC phase-cut dimming control which can be implemented using either leading edge or trailing edge TRIAC dimmers.

All models have a 180 to 295V AC input range; each with different output current and voltage capabilities. Constant current single outputs from 350 to 2400mA are available. Efficiency rating is up to 88%, meaning that they need only free air convection cooling for -30 to 50˚C ambient temperature operation. This makes them suitable for either outdoor LED lighting or indoor decorative lighting applications.

Single-stage PFC topology allows the four products to meet the requirements of high power factor - greater than 0.9 – and EN61000-3-2 Class C (harmonic current) specifications for the lighting industry. They have Class ll no Frame Ground design and double insulation and 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.
