Dialight has announced an ultra-durable Vigilant LED high bay 480V passive power supply, offering higher energy efficiency to outperform conventional SMPS technology in high-voltage applications. The device debuts on the 18,000lm 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 maximise ROI even in the harshest conditions.

In addition to offering a high power factor and very low THD rating, the system emits extremely low EM signals to minimise interference and maximise 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 and ships with 6kV surge protection.

Rizwan Ahmad, Vice President, Electronic Division, Dialight, comments: “Unlike most LED lighting fixture manufacturers that rely on off-the-shelf power drivers, Dialight has long been a pioneer in developing our own power supplies to overcome the ‘weak link’ in most LED lighting systems. This latest innovation once again propels us far ahead of the competition in delivering the most durable and dependable industrial LED lighting solutions in the world. This system makes about the headache of fixture failure due to weak 480V drivers a thing of the past.”
