First, the design features 
 ? With a USB interface, and equipped with special U-disk data can be deposited in the discharge process of high-speed acquisition voltage, current, and transient voltage waveform recording and U disk, import the PC. PC data management software on the battery discharge process analysis, and generate a corresponding data report. 
 ? Large-screen touch screen display, touch operation, convenient, intuitive, display data of the screen the whole significantly. 
 ? Largest stand-alone power 0 ~ 100KW continuously adjustable, more power and machine work. 
 ? Three-phase current can be arbitrarily set between 0 ~ 160A, the device can work under the conditions of the three-phase power imbalance. 
 ? AC and DC load functions in one machine: the ability to automatically identify the AC and DC two voltage, can be used as AC load can also be used as a DC load to meet the discharge requirements of the UPS battery pack. 
 ? Load time can be the root tree customer request to be set from 0 to 99 hours continuously adjustable, minutes adjustment. 
 ? Intelligent MCU ARM control, LCD Chinese display. 
 ? Different currents can be set to stop time, discharge power, the voltage threshold (upper and lower limits can be devices). 
 ? E-STOP is an emergency stop switch. 
 ? Three-phase voltage is too high, the system automatically stops the discharge. 
 ? Three-phase voltage is too low, the system automatically stops the discharge. 
 ? Has over-current short circuit protection. 
 ? A fan open to power failure or malfunction, alert at the same time to load automatically trip and disconnect the power. 
 ? Main power devices using PTC ceramic resistor, red-hot phenomenon, does not cause overheating of ignition accident. 

 Second, the product features 
 ? Load function: an intelligent load to the exchange of equipment, you can set a different current, stop time and other conditions of discharge. 
 ? Test function: the ability to measure the measured power of each phase and phase combined active power, reactive power, apparent power, functional volume and function of the volume, while measuring the phase current, RMS voltage, power factor, phase angle, frequency and power load capacity. Has a powerful wireless capabilities. 
 ? Management functions: a powerful computer system will record and analysis of test data, a detailed and complete report.
