With the enhancement of microprocessor´s ability to control power electronics, load current management is becoming more and more effective. The output current control technology is developing with the development of semiconductor switches.

The load manager has built-in intelligent functions, including programmable current level feedback to the microprocessor and digital current level reading. This information is stored in microprocessors that handle timing sampling of events to create record level history. Then the software is used to determine the change of load current with time. This information is compared with the programmed threshold and can alert the user to changes.

In the case of load, the information can be used to alarm the impending component failure. This intelligent load management product can be run as a single entity or used with smart power. When used with intelligent power supply, RS-485 communication can be used for programmable load monitoring and real-time updating.

The enhancement of load manager capability is changing the power industry. The ability of digital control becomes more accurate and adjustable, and the performance and reliability of the system are also improved. Therefore, it can predict the failure and greatly reduce the maintenance cost.
