RQB150W12 Railway DC-DC Converters
MEAN WELL RQB150W12 Railway DC-DC Converters are available in a quarter-brick package with industrial standard pinout and an ultra-wide 12:1 input range of 14VDC to 160VDC. These 150W encapsulated modules cover the mainstream nominal voltages of global railway systems (24VDC to 110VDC) and operate under extreme environments of -40°C to +90°C. An external capacitor can be added to ensure the hold-up time lasts for 10ms to 30ms while the DC input is temporarily unstable. Additional features include 3KVAC isolation withstand voltage and complete protections: overload, overtemperature, overvoltage, input undervoltage lockout, and continuous short circuit. MEAN WELL RQB150W12 DC-DC converters are suitable for railway, tram, and bus systems, telecom/datacom systems, and wireless networks. The devices also can be used in harsh environments with high vibration, high dust, or extremely low or high temperatures.
