EN50155-Compliant DC-DC Converters for Railway Applications
Page 1 of 1
A new family of board mount DC-DC converters has been developed for railway applications. The VQB100R and VHB150R series modules from CUI are designed to comply with the EN50155 standard, which specifies input, EMC, mechanical and environmental requirements. The internally potted and encapsulated design provides increased system reliability through added protection from environmental factors such as dust, moisture, shock and vibration.
Offered in industry standard quarter brick and half brick footprints respectively, the 100W VQB100R series and the 150W VHB150R series are highly efficient, reaching levels up to 92.5%. Though the modules are designed primarily for railway applications, the VQB100R and VHB100R series also target designs that may experience high transients, including telecom systems and battery-powered equipment.
The DC-DC converters provide a 3:1 input range of 66~160 VDC and output voltage options of 5, 12, or 24 VDC. They are designed to deliver a case operating temperature range of -40° to 100°C and provide 2250 VDC I/O isolation. Protections for over voltage, over current, short circuit, under voltage lockout and over temperature are included. Additionally, all models offer remote on/off control, remote sense, and carry CE and UL/cUL 60950-1 safety certifications. The VQB100R and VHB150R series are priced starting at $119 in quantity 100.
