New LED driver meets critical EMI / EMC global lighting standards

New from Gresham Power Electronics, the LB115 power supply family is intended for LED architectural lighting applications. The power supply series delivers 115W from a compact 2 x 4 x 1.2 inch footprint and has a built in EMI filter to meet EN55015 class B requirements for lighting fixtures. The LB115 is a single output internal power supply with a wide operating temperature range that is ideal for low power LED applications. These include building and stage lighting systems which require an efficient and compact power solution. The LB115 features a universal input of 90 to 264Vac and is available in four models with output voltages of 12, 24, 48 and 56VDC. The LB115 features a convection cooled rating of 75W and a maximum air cooled rating of 115W with 200 LFM, which is delivered throughout the wide operating temperature range from -20C to +50C. The LB115 starts up at -40C and can operate safely in elevated temperatures with reduced output loading providing a remarkable -40C to +70C temperature range. In addition, the LB115 series has active Power Factor Correction (PFC) and meets the critical requirements of the European Union for harmonic distortion in accordance to IEC61000-3-2 Class C from 0% dimming (less than 1Watt) to full dimming. Fully compliant to applicable safety and EMC standards, these Level V efficiency compliant power supplies allow easy integration into many LED, industrial and ITE applications. All four models, ranging from 12V to 56V, are CE marked to the low-voltage directive and approved to standards of UL/CSA/IEC/EN60950-1 2nd edition. Dave Wellman, sales manager, Gresham Power Electronics, said, "The new LB115 LED Driver family meets global EMI and EMC lighting requirements, providing design engineers with an easy-to-integrate power supply on a standard platform that reduces time to market and eliminates a costly EMI filter. Customers now demand the very high efficiencies and superior EMC performance which can be found in our LED power supplies. The new LB115 is the perfect blend of small size, excellent efficiencies and high quality at a very competitive price."
