LED High Bay Passive Power Supply
Dialight, Farmingdale, N.J., debuted its new ultra-durable 480V Passive Power Supply, offering higher energy efficiency to outperform conventional switch mode power supply (SMPS) technology in high-voltage applications.
The new 480V Passive Power Supply works on the 18,000-lumen package and will become the standard power supply used on every new Dialight fixture designed for high-voltage applications.
With large inductance and minimal use of semiconductors, this custom-designed passive system provides superior surge immunity to withstand high-voltage power quality issues to deliver a reliable, long-life lighting solution in 480V applications.
In addition to offering a high-power factor and very low total harmonic distortion (THD) rating, the system also emits extremely low electromagnetic signal to minimize interference and maximize energy efficiency. The product is rated for operation at full power even in high-temperature environments without the need for LED current reduction.
