  • Leakage Current
  • A term relating to current flowing between the AC supply wires and earth ground. The term does not necessarily denote a fault condition. In power supplies, leakage current usually refers to the 60 Hertz current which flows through the EMI filter capacitors which are connected between the AC lines and ground (Y caps).
  • Line Interactive UPS
  • A type of uninterruptible power supply that is in standby mode most of the time but contains a transformer that helps condition and adjust the voltage until the voltage exceeds a set limit. If the voltage limit is exceeded, the UPS can support the load until the voltage returns to within the limits or the battery is drained.
