Trains operate on high-voltage power supplies (DC or AC). However, the quality of that power can fluctuate wildly. When a train accelerates, brakes, or passes over a gap in the power line, massive voltage spikes and surges occur. on how equipment must handle these surges. A device compliant with this standard must survive voltage transients without failing—and without emitting interference that could disrupt other systems.
In many projects, compliance with IEC 60571 is required alongside (electronic equipment for rolling stock) – indeed, IEC 60571 and EN 50155 are technically aligned for most requirements, but EN 50155 is more common in European procurement. IEC 60571 is often used globally as a baseline. Iec 60571.pdf
Some of the key aspects of IEC 60571 include: Trains operate on high-voltage power supplies (DC or AC)
But unlike your smartphone, which lives a pampered life in a pocket, train electronics are born into a warzone of vibrations, voltage spikes, and extreme temperatures. on how equipment must handle these surges
