Leakage Current Requirements For Medical Power

Should network cabinet power supplies be protected against leakage current

It is important to limit leakage current in order to protect users from dangerous touch voltage and prevent faults from occurring in the system. While these capacitors are essential for electromagnetic compatibility (EMC), they. Minimizing leakage current is essential to prevent electrical shock, reduce power losses, and ensure compliance with regulatory standards. Due to EMI requirement for the power supply, there are Y capacitors connected in between AC L/N and PE conductor.
