LED power supply with multiple stage output current and DALI control function

LCM-40(DA) / 60(DA)

PEWATRON introduces Mean  Well’s LCM-40W/60W multiple-stage output current LED power supply series  With “constant current output” design, the output current level can be flexibly selected by the DIP switch. The basic models, LCM-40 and LCM-60, are designed with “2-in-1” dimming function (0…10Vdc and PWM signal), while the digital control models, LCM-40DA and LCM-60DA, have a DALI interface and a push dimming function. These units fulfil the increasing demands for intelligent digital dimming applications. Featuring 180~295 VAC and built-in two stage PFC function, these new series comply with harmonic current limitation per EN61000-3-2 Class C (>35% load) and also fulfil PF>0.9 if loading over 35%. In addition, they possess 2kV surge immunity ability (EN61000-4-5, heavy industry level) between Line and Neutral, which complies with the related lighting requirements.

With high performance efficiency up to 91.5% the units can be operated at free air convection from -30°C to +60°C ambient temperature. Thanks to the temperature compensation function and the possibility to connect an external temperature sensor (NTC thermistor, not supplied with the unit), the output current can be changed with the detected temperature to ensure the long lifetime of LED’s. In addition, they are equipped with synchronization dimming function that can operate max. 10 drivers synchronously in response to the dimming control signal of LED lighting systems with multiple lighting fixtures. The Class II design without frame ground has built-in 12V/ 50mA auxiliary output (for an external fan), protections against short circuit, over voltage and over temperature. All of them comply with the norms per UL8750, ENEC EN61347-2-13 and EN62384 for lighting regulations. The DA-types do also comply with IEC62386-101, 102, 207 norms per DALI lighting control systems. Suitable applications include LED commercial lighting, office lighting, indoor LED decorative lighting etc.
