DC/DC converters target railway applications

Murata has launched the UCR100 series of dc/dc converters, targeted at railway power conversion and battery applications.

Accommodating an 8:1 input range, from 16.8 to 137.5VDC, the UCR100 series comprises three single output models providing 5, 12, or 24VDC outputs. Additional model specific options include current share, holdup and an adjustable undervoltage lockout feature. The UCR100 devices are packaged in a Euro Cassette format measuring 3U x 4TE x 165mm, and are said to offer ease of installation and better energy efficiency ratings than comparable models. According to Murata, a single UCR module can typically take the place of up to five alternative modules. The devices have an active current share option that allows multiple UCR converters to connect in parallel to support higher output current or to achieve high system reliability through redundancy. They all conform to relevant transportation industry safety standards, including EN50155, EN50116, IEC60571, RIA12 and IEC/EN/UL60950-1.
