Therefore, to meet the demand for a wider voltage input range, MEAN WELL presents the new RQB150W12 series encapsulated module with an ultra-wide 12:1 input voltage ratio, a 1/4 brick format, and 150W power rating. These converters will be distributed in Spain and Portugal by Electrónica OLFER.
Key features include an ultra-wide input voltage range (14-160VDC), which can cover the main nominal voltages of any railway system (24/36/48/72/96/110VDC). These converters are designed to operate in extreme environments (from -40°C to +90°C) and can be fitted with an external capacitor to ensure a hold-up time of between 10 and 30ms when the DC input is temporarily unstable.
This device has a high isolation voltage of 3KVAC and comprehensive protection features. It is an ideal product for railways, trams, MRT, buses and information networks, industrial automation, communication equipment, DC UPS systems, etc.
