Power-dense and highly efficient, the units feature a universal AC input of 90 to 305VAC and DC output range from 12 to 48V. In addition, the LU500’s small footprint allows it to fit comfortably into a 2U chassis and provides up to 500 watts with moving air, higher than any power supply in its class. Meeting IEC61000-3-2 class C with PF of greater than 0.9 and EMI compliance to CISPR 15 or EN55015 for lighting, the new LU500 features active current sharing for parallel operation to deliver up to 1,000 watts for higher power needs. With an average efficiency of over 90%, the LU500 comes in a 4” X 7.25” X 2.2” chassis and features full output protection with over-temperature sensing circuits that will shut down the power supply – thus protecting the light fixture in case of overheating.

“We are constantly achieving higher wattages at very attractive efficiency levels for our LED and entertainment equipment designers,” said Maggie Nadjmi, product manager for SL Power Electronics. “The LU500’s performance, with one or two-phase input capability coupled with efficiency and full EMI/EMC compliance, makes this power supply a great solution for our global customers.”

Featuring a three-year warranty, the RoHS compliant LU500 models have more than 500,000 hours of MTBF operating at 25°C.
