摘要
A power distribution unit (PDU) inrush current monitor (PICM) may be used to protect an uninterruptible power supply (UPS) from an inrush current from a PDU. In general, the PICM senses a power condition of the PDU (e.g., energized or de-energized) and places the UPS in the appropriate operational state or mode (e.g., a stop mode or a run mode) to avoid an inrush current to the UPS when the PDU is powered on and energized. The PICM thus protects the UPS while allowing the UPS to operate when needed. In one embodiment, the PICM provides a stop signal to the UPS to place the UPS into a stop mode while the PDU is de-energized and provides a run signal to the UPS to place the UPS into a run mode after the PDU is energized.
