Each instance of this class represents a power supply in the system. It is used to monitor their status and to indicate when a power supply is malfunctioning and needs attention.
Power supply is critical and should never fail, which is why servers often have redundant power supplies. Monitoring power supplies allows the operators to be alerted when a power supply fails, or in some cases when a power supply is overloaded. Depending on the information available, the Used Capacity and/or Status parameters will be displayed for each power supply or power unit device:
●The Used Capacity parameter represents the power supply’s power currently in use in percentage. An alert is triggered if the computer uses too much power than it can be supplied. ●The Status parameter represents the current status of the power supply. An alert is triggered if an error occurs with the power supply.

 "Status" is a text parameter that describes the overall status of the corresponding device or sensor. Alert conditions describe in symbolic terms what occurs in the "Status" parameter when thresholds are breached: one exclamation mark triggers a warning; two exclamation marks raise an alarm.
Example
If BPM Express for Hardware detects that manufacturer-specified thresholds for power supply have been breached, the Status parameter will report “Warning! Problem: This power supply is in degraded state, or about to fail” or “Alarm!! The power consumed by the system is out of the supported range", or as may be the case. The history graph shows the exact details of the problem, its consequences and recommended actions.

 Depending on your system, all parameters may not be used.
