LCM-25(DA) Constant Current LED Drivers for Low-Wattage Intelligent Lighting Systems

After releasing the 40 W LCM-40(DA) and the 60 W LCM-60(DA) series, Mean Well extends downward to the new 25 W multiple-stage constant current output LED power supply, LCM-25(DA), to meet the demands of intelligent LED lighting control and to provide the lower wattage power solution for project style lighting design.

Features:
•   Output current level selectable by DIP switch
•   180~277VAC input range
•   Built-in active PFC function
•   Protections: short circuit, over temperature
•   Cooling by free air convection
•   Fully insulated plastic enclosure, IP20 design
•   Class II power unit, no FG
•   Built-in 0~10VDC and PWM signal dimming function (LCM-25)
•   Built-in DALI interface and push dimming function (LCM-25DA)
•   No load power consumption <0.5W
•   Power supply synchronization function up to 10 units
•   Dimension(LxWxH): 105x 68x 23mm
•   3 years warranty

Exploiting the “constant current output (C.C.)” design, the output current level can be flexibly selected by the built-in DIP switch by users. The basic model, LCM-25 is designed with the built-in 2 in 1 dimming function (0~10 Vdc and PWM signal), whereas the digital control model, LCM-25DA, is equipped with the DALI interface and push dimming function. These launched units can fulfill the increasing needs of intelligent digital dimming applications. Accepting 180~277 VAC input and the built-in two stage PFC function, LCM-25(DA) series observes the harmonic current limitation per EN61000-3-2 Class C (>50% load). In addition, it possesses 2 kV heavy-industry level surge immunity capability between Line and Neutral, following the related luminary requirements.

With the new generation electric circuit topology, LCM-25(DA) provides the efficiency up to 86%, so it can be cooled by free air convection from -30°C to +60°C ambient temperature. This series is designed with the synchronization dimming function that up to 10 drivers can be controlled synchronously to make the dimming control signals of the LED lighting system with multiple lighting fixtures consistent. LCM-25(DA) is a rectangular and low-profile (23mm) plastic enclosed power supply. Different from the general design with input at the front and output at the rear, the I/O connection of this new model is on the same side, which allows system designers to sufficiently take use of the limited space when wiring and installing the units. Other standard functions encompass Class II design (no FG), protections for short circuit and over temperature. LDM-25(DA) is certified with various international lighting safety regulations such as UL8750, ENEC EN61347-2-13, and EN62384. LCM-25DA is also complied with IEC62386-101, 102, 207 norms per DALI lighting control systems. Suitable applications include LED commercial lighting, LED office lighting, indoor LED decorative lighting, and etc.
