July 8, 2014 - Offering up to 86% efficiency, LCM-25 and LCM-25DA 25 W LED power supplies let designers implement low-wattage intelligent LED lighting control systems and project style lighting designs. Output can be set to levels from 350 mA to over 1 A via built-in DIP switch. While LCM-25 features2-in-1 dimming function that can be driven by 0–10 Vdc or by PWM control inputs, digital LCM-25DA is additionally equipped withDALI interface and pushbutton dimming function.

Aldermaston, UK – Sunpower’s new LCM-25(DA) 25 W constant current LED power supply allows designers to implement low-wattage intelligent LED lighting control systems and project style lighting designs. The LCM 25(DA) is the latest addition to the LCM series which already includes 40 W and 60 W constant current products. Its output, while maintaining a constant current to meet LED requirements, can be flexibly set to different levels from 350 mA to over an amp by a built-in DIP switch. The LCM-25 features a 2 in 1 Dimming Function which can be driven either by 0-10 VDC or by PWM control inputs. The digital LCM-25DA is additionally equipped with a DALI interface and pushbutton dimming function. LCM-25(DA)s can be synchronised so that up to 10 of these LED drivers can be simultaneously controlled from a single dimming command.

The LCM-25(DA) operates from 180 – 277 VAC input and, with built-in active PFC, meets the harmonic current limitation set by EN61000-3-2 Class C (> 50% load). In line with related luminary requirements, it also has 2 kV heavy-industry surge-level immunity between line and neutral. With next-generation circuit design, the LCM-25(DA) provides up to 86% efficiency, allowing cooling simply by free air convection in ambient temperatures from -30C to +60C. No-load power consumption is less than 0.5 W.

The LCM-50(DA) is a rectangular, low profile (23 mm) fully insulated IP20 rated plastic enclosed power supply offering a unique feature for ease of installation; unlike the industry standard design of inputs at the front and outputs at the rear, all LCM-50(DA) I/O connections are along one side of the enclosure. This enables easy access, with efficient use of limited space during installation and wiring.

The supplies feature Class ll design with no frame ground and protection from short circuit and over temperature. International lighting safety regulation certification includes UL8750, CSA C22.2 No. 250.0-08, ENEC EN61347-2-13, and EN62384. Additionally, the LCM-25DA complies with IEC62386-101, 102 and 207 norms for DALI lighting control systems.

“The LCM-25(DA) offers both installers and users great flexibility in meeting the increasing demands of intelligent dimming applications” commented Andy Wall, CEO of Sunpower Technology, “Yet, even with their flexibility and intelligence, these systems can be widely distributed, as the furthest slave can be up to 120 m from the master unit. They can be used for both indoor and outdoor LED lighting applications, including LED decorative, office and commercial lighting – and a three-year warranty comes as standard.”
