MEAN WELL Rugged Wide Input DC-DC converter for Railway Telemetry

Onboard telematic systems for Railway applications must be robust, able to handle constant vibration, a wide range of temperature fluctuations, and be resistant to dust and moisture. MEAN WELL has launched the RQB150W12 Series, the latest in railway DC to DC converters for telematic systems.


The MEAN WELL RQB150W12 series are an encapsulated module type, within an ultralow-profile body to ensure they consume minimal real estate. Although small, these converters can accept a wide input voltage range (14V ~ 160V, 12:1) and provide outputs of the most commonly used voltages,12, 24,48, & 54V. Protections are provided for short-circuit, overload, overvoltage, overtemperature and input under-voltage.

The RQB150W12 series has a wide temperature range of -40°c - +90°c, so they can handle most climatic conditions that locomotives and multiple units may encounter. More importantly, they comply with railway standard EN50155. This standard covers aspects including temperature, humidity, shock, vibration, as well as other parameters, all of which are present in the rugged environments the railway industry must endure. 


The MEAN WELL RQB150W12 Series is a versatile solution for railway telematics, metro rapid transit, trams and buses, and other mobile equipment applications.
