The NPF-D series from Mean Well is a AC/DC LED driver that features a constant current mode output with dimming. It is designed to operate from 90~305Vac and offers a variety of output currents, selected by a range of voltages from 12V to 54V. These LED power supplies are efficient up to 90% and thus don't require anything more than free air convection for cooling. The shape is similar to a standard ballast or 'butterstick style', it includes mounting holes for securing down and is IP67 rated for dry, damp or wet locations. To control the output, the NPF features 3 in 1 dimming: 0~10V, 10V PWM, or resistance. This flexibility provides a great feature when designing lighting systems and with a 5-year warranty, gives the end-user a reliable product for driving LEDs.
