ERM03H72

直流/直流转换器 隔离式板载, ITE, 1输出, 75 W, 24 V, 3.125 A

The from is an ERM75 series high performance 75W isolated DC to DC converter module. It is specially designed specifically for railway applications. Fully encapsulated in a metal case with an isolated baseplate, the converter has an industry-standard 2.28inch x 1.45inch 57.9mm x 36.8mm quarter-brick footprint and a height of just 0.5inch 12.7mm. Reinforced insulation rated at 3000VAC RMS and high EMI immunity qualifies it for many demanding applications in railway and other transportation systems. Advanced circuit topology provides up to 92% efficiency and allows the converter to accommodate ambient operating temperatures as high as 85˚C with suitable derating. An optional heatsink is available. Further features include differential remote sense, remote On/Off and undervoltage shutdown as well as overload and short-circuit protection.
