RQB40W12 & RQB150W3 DC-DC Converters

MEAN WELL RQB40W12 and RQB150W3 DC-DC Converters feature 2KV_AC/3KV_AC high isolation voltages, high efficiency, and come in a quarter-brick package. These DC-DC converters feature an ultra-wide input range and a wide operating temperature range of -40°C to 90°C. The RQB40W12 and RQB150W3 DC-DC converters comply with railway standard EN50155 and offer remote ON/OFF control and remote sense. These MEAN WELL DC-DC converters offer various protection features, including short-circuit, overload, overtemperature, overvoltage, and input undervoltage lockout. Typical applications include railway systems, telecom/datacom systems, wireless networks, industrial control facilities, and analyzers.
