ERM75 High Input Range Series
Active
75 W DC-DC Converters (High Input Models)
The ERM75 series 75 W isolated DC-DC converter modules are designed for railway applications. Low-input models feature a 43 to 101 VDC input range and high-input models 66 to 160 VDC, all complying with EN50155 standard for electronic equipment used on rolling stock. You also have a choice of single-output models offering 5, 12, 15, or 24 VDC.
Featuring reinforced insulation rated at 3000 VAC RMS, all models offer differential remote sense, remote On/Off and undervoltage shutdown, as well as overload and short-circuit protection. Maximum efficiency is 92% and operating temperature up to 80℃ ambient with suitable derating.
They are available fully encapsulated in metal case with an isolated baseplate, offering an industry-standard 2.28 x 1.45-inch (57.9 x 36.8 mm) quarter-brick footprint and 0.5-inch (12.7 mm) height.
