Rugged, constant current power supply drives large-scale LED lighting installations – with dimming
Sunpower’s PLEC-035S035DT power supply provides up to 100 VDC output at 350 mA. Its constant current capability makes it ideal for driving large LED lighting arrays. This 35 W supply automatically delivers a consistent, optimum current into a series string of any length from 9 to 28 LED lamps. Parallel LED strings can also be added, subject to the total output current capacity of the power supply. LED brightness can be set by a dimming control using a potentiometer or 0 – 10 Vdc input signal.The
The PLEC-035S035DT is just one member of Sunpower’s PLEC-035SxxxDT Series, which gives professional LED lighting designers and installers a wide choice of DC output voltage and current configurations. The series comprises nine constant current 35 W models with output currents ranging from 2900 mA to 350 mA, and output voltages from 12 to 100 Vdc. All models can be specified without the dimming function if so desired. Users can choose the higher output current models for predominantly parallel LED lamp arrays, or the higher output voltage models for predominantly serial LED lamp strings.
Applications for the PLEC-035SxxxDT Series include solid state lighting, moving signs, backlighting, LED-based decorative lighting, LED-based architectural lighting, LED stage and theatre lighting and LED electronic displays.
