TDK-Lambda has developed a new range of power supplies specifically targeted towards LED applications requiring high reliability. Perfectly suited for all indoor and outdoor LED lighting installations, as well as digital signage and industrial applications, these 12W supplies are IP66-rated and accept a wide universal AC input.
The new LED power supplies are available in two output modes – the ALV12 series provides a constant voltage of 12V, 15V and 24V and the ALC12 series provides a constant current of 350mA and 700mA. Both series are convection cooled, operating between -10 and +60°C without derating, with a guaranteed start up at -20°C and an output efficiency of 82%. Standard features include short circuit, over load and overvoltage protection. The units are compact, measuring 90 x 34.5 x 21mm, and are mounted in a vibration and shock resilient sealed case.
As well as being EN55015, EN55022, VCCI, CISPR22 and FCC compliant (achieving class B conducted and radiated emissions with a substantial margin), TDK-Lambda’s ALV12 and ALC12 series meet UL1310 (Class 2), EN61347-1 and EN61347-2-13 safety approvals and carry the CE mark. To ensure long term reliability all models meet EN61000-4-2, -3, -4, -5, -6, -8, -11 immunity standards together with a MTBF of over 700,000 hours and a calculated e-cap life of up to 10 years, supported by a three-year warranty.
