MEAN WELL has been a pioneer in railway telematics for several years, earning widespread industry acclaim for its encapsulated, enclosed, and DIN rail-mounted modules ranging from 8 to 500W (detailed specifications outlined in the table below). To cater to the need for broader voltage input ranges, we proudly introduce the newly developed RQB150W12 series, a 1/4 brick encapsulated module offering an ultra-wide voltage input of 150W and a 12:1 ratio (14~160Vdc).
Key highlights include:

        · An ultra-wide voltage input range of 14~160Vdc, capable of accommodating the nominal voltages prevalent in global railway systems (24/36/48/72/96/110Vdc).
       · Operation under extreme temperatures spanning -40°C to +90°C.
       · Optional external capacitor to maintain hold-up time between 10~30 ms during temporary DC input instability.
       · High isolation withstand voltage of 3KVac.
       · Comprehensive protection features.

This versatile module is ideally suited for applications in railways, trams, MRTs, buses, information networks, industrial control automation, communication equipment requiring double-layer isolation, DC UPS systems, battery voltage conversion, voltage stabilization, and more.
