TDK-Lambda power supplies target LED applications

TDK-Lambda has developed a range of power supplies targeted at LED applications requiring high reliability.

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 LED power supplies are available in two output modes - the LDV12 series provides a constant voltage of 12, 15 and 24V and the LDC12 series provides a constant current of 350 and 700mA.

Both series are convection cooled, operating between -10 and 60C without derating, with a guaranteed start up at -20C and an output efficiency of 82 per cent.

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 LDV12 and LDC12 series meet UL1310 (Class 2), EN61347-1 and EN61347-2-13 safety approvals and carry the CE mark.

All models meet EN61000-4-2, -3, -4, -5, -6, -8 and -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.
