The SL Power Electronics LE500 Family of IP67 power supplies is a superior performance 500 Watt AC to DC power supply designed to ensure easy integration into LED driver applications. It has a universal AC input range of 90 to 305 VAC. Highly efficient, the LE500 product family has droop current share for redundant/paralleling for higher power applications. All models are CE marked to low voltage directive and approved to safety standard EN60950 2nd edition and UL8750. This family of products come in a compact size and has industry leading grams per watt weight to power ratio. The LE500 family is IP67 rated for the most rugged environment. In addition, this model family has enhanced Electro-Magnetic Compatibility (EMC) features offering heavy industrial ESD, AC mains surge and RF immunity resulting in a more robust and reliable product. The LE500 families’ AC mains emissions comply with FCC class B & EN55015 standards. Output emissions for differential ripple and common mode voltage and current have been reduced to minimize system level EMI and system circuit interference.

For long-term reliability, this model family has been designed using high-quality components to provide long life, thoroughly tested and approved by regulatory agencies. See the product datasheet for more details.
