Power supplies deliver 115W for architectural LED lighting

Offering a universal input of 90-264VAC, the power supplies are available with output voltages ranging from 12 to 56V. From a -20 to +50ºC temperature range, a convection cooled rating of 75W and a maximum air cooled rating of 115W with 200 LFM is delivered. Starting up at -40ºC, the power supplies can operate safely in elevated temperatures with reduced output loading, providing a -40 to +70ºC temperature range. Suitable for space constrained applications, the power supplies feature PFC. From 0% dimming (less than 1W) to full dimming, the LB115 power supplies provide the European Union for harmonic distortion in accordance to IEC61000-3-2 Class C.

The power supplies, which are compliant to applicable safety and EMC standards, can be easily integrated into a number of LED, industrial and ITE applications. The Level V efficiency compliant power supply series is approved to standards of UL/CSA/IEC/EN60950-1 2nd edition and CE marked to the low-voltage directive.

“The LB115 family meets global EMI and EMC lighting requirements, giving design engineers an easy-to-integrate power supply on a standard platform that reduces time to market and eliminates a costly EMI filter,” said Maggie Nadjmi, Product Manager, SL Power Electronics. “Our customers have come to expect very high efficiencies and superior EMC performance in our LED power supplies. The LB115 is the perfect blend of small size, excellent efficiencies and high quality at a very attractive price point.”

The LB115 power supplies, which are RoHS compliant, provide more than 574,000 hours of MTBF at 25°C ambient. Offered with a three-year warranty, the power supplies are sold in 500 piece orders and priced from $39.
