The 480 V Passive Power Supply debuts 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, Dialight’s 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. This longevity and performance, backed by Dialight’s industry-leading 10-year full-performance warranty, virtually eliminates lighting maintenance to maximize ROI even in the harshest conditions.
In addition to offering a high power factor and very low total harmonic distortion (THD) rating, the system 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. The system’s robust design is thoroughly tested through Dialight’s in-house Accelerated Life Test (ALT) and ships with 6kV surge protection
