ConTech’s new RQF series of railway DC-DC converters offers 50 Watts of fully regulated output power with nominal railway input voltages of 72 V (43 - 101 V) and 110 V (66 - 160 V). Single outputs offered are 5, 12, 15 and 24 V.
The devices come in an industry standard quarter brick package which can be ordered with an optional heatsink. They operate with efficiencies as high as 92% and handle baseplate temperatures in the range of -40°C to +105°C. The unit is encapsulated with a thermally conductive potting compound and uses a metal baseplate for improved thermal performance.
Features include remote on/off, output trim, over-temperature, overload and short circuit protection. The RQF series is RoHS compliant and meets railway standards EN50155 and EN45545-2, EMC standard EN50121-3-2 as well as UL 60950-1.
