Introduction
MEAN WELL has been deeply engaged in railway telematics for years, offering a wide portfolio of encapsulated modules, enclosed types, and DIN rail power supplies ranging from 8W to 500W. These solutions have earned strong recognition across the industry.
To further meet the growing demand for ultra-wide input ranges, MEAN WELL is introducing the new RQB150W12 series—a fully encapsulated 1/4 brick, 150W DC/DC converter with an impressive 12:1 input range (14~160Vdc).
This series is designed to cover the mainstream nominal voltages of global railway systems (24/36/48/72/96/110Vdc) and can operate reliably in extreme environments from -40°C to +90°C. With the option to add an external capacitor, it ensures 10–30 ms hold-up time even under unstable DC input.
Built with 3KVac high isolation, complete protection features, and compliance with railway, ITE, and safety certifications, the RQB150W12 series is ideal for demanding applications such as railways, trams, MRT systems, buses, information networks, industrial automation, communication equipment, DC UPS systems, and battery voltage conversion or stabilization.
