San Diego, CA – October 2009 – TDK-Lambda has released the LD12 series of AC-DC power supplies that are designed for LED lighting and display applications with output ratings up to 12.6 watts. Both constant-voltage and constant-current models are available. These 12-watt AC-DC encapsulated drivers/supplies are designed to meet IP66 (splash proof) standards and operate with universal power inputs of 90 to 265VAC.
The constant-voltage models (LDV12 series) are available with 12V, 15V or 24V outputs. While the constant-current units (LDC12 series) provide from 350mA up to 750mA with DC output ranges of either 3-18V or 3-36V. All models are convection cooled and can operate with an ambient temperature from -10°C to +60°C. They are guaranteed to start-up at low temperatures down to -20°C. Typical output efficiencies are 82% under full load. Other standard features include short-circuit, overcurrent and overvoltage protections.
These power supplies meet EN55011-B/EN55022-B, EN55015, VCCI-B, CISPR22-B and FCC-B EMI and EMC standards (conducted and radiated). In addition, these units are safety agency approved to UL1310 (Class 2), IEC61347-1, IEC61347-2-13 and carry the CE mark. All supplies come with a 3-year warranty.
The LDV12 and LDC12 series are available now and priced from $14.50 each in quantities of 1k units. For more information, please call TDK-Lambda directly at 1-800-LAMBDA-4 or view our full specifications for these power supplies at:
