ERM50 High Input Range Series
Active
50 W DC-DC Converters (High Input Models)
The 50 W ERM50 series isolated DC-DC converter modules for railway and transportation systems feature an input voltage range of 66 to 160 VDC with a choice of four single output models, 5, 12, 15, and 24 VDC. The converters offer up to 92% efficiency and maximum ambient operating temperature of 85℃ with suitable derating. The series complies with EN50155 standard for electronic equipment used on rolling stock. Standard features include 3000 VAC RMS reinforced insulation, differential remote sense, remote On/Off, undervoltage shutdown, and overload and short-circuit protection. The modules are fully encapsulated in metal case with isolated baseplate and have an industry-standard 2.28 x 1.45-inch (57.9 x 36.8 mm) quarter-brick footprint with 0.5-inch (12.7 mm) height.
