System Principle of Product Equipment
The equipment take on a modular DSP control as a centrifugal point. In practice, when the system is functioning, the charging system energizes the battery using one of its modes: constant current constant voltage (CCCV). The energy feedback system takes the product energy of electrical energy and converts it while discharging into sine waves/stipulations and feed it back into the based energy grid with an efficiency of 88%. The four-wire sampling in combination with Agilent technology allows voltage/current accuracy controlled through the connected device at of ±0.03%. The host computer then connects with the system via TCP/IP communications, and is collecting real-time information of variables such as; voltage and current, and also becomes multi-dimensional monitor with the addition devices such as paired temperature and or voltage modules. Dual fans for forced air cooling at the hardware level, forcing the heated air outward, along thermal imager simulation and control during testing and multiple protection measures (overvoltage, overcurrent, reverse coupling, and etc.) allow the machine safety measures with device using it safety controlled. The overall design of system and process continued on multiple testing, grading, and towards provide type of data management.
