Power supply for LED applications
November 2013
Electrical Power & Protection
Mean Well has introduced a 40 W AC/DC power supply to fulfil requirements of the LED lighting market. Featuring 110-295 VAC input range, these new units have six selectable constant current outputs from 350-1750 mA. With single stage PFC circuit design, PLM-40 series is a cost effective power solution to reach high PF values. It also complies with harmonic current limitation per EN61000-3-2 Class C and features no load power consumption <0,5 W and set up time < 500 ms, which comply with the ErP regulations required by the European Union for lighting fixtures.
PLM-40 series possess up to 88% efficiency and can work between -30 and 45° using only free air convection cooling. Enclosed in an UL 94V-0 rated plastic case and Class II AC input design (two wires, without FG), these units effectively protect users from electric shock. Different from the general wire-style I/O connection, PLM-40 series are designed with a screw-less push clamp terminal block for more convenient wiring installation. Other standard functions include short circuit and over temperature protections. In addition, the full series complies with global certificates per ENEC EN61347-2-13, EN62384, UL8750, CB, and CE lighting related regulations. Suitable applications include indoor LED lighting, office lighting, commercial lighting, and indoor LED decorative lighting.
