I. Product Overview: 
 Charge HDGC3970 smart charging and real-time monitoring of the machine set in one, reducing business costs and reduce the labor intensity of the maintenance personnel, the maintenance of the batteries and the UPS power supply to provide a comprehensive scientific testing means. 
 This machine adopts imported high-quality components, intelligent three-stage charging mode, Equalize / Float automatic conversion; battery voltage in real-time online polling, real-time online display, testing, record the voltage of the battery; large-screen LCD display, Chinese menu prompt, easy operation, high degree of intelligence, you can set the parameters of voltage, current, time, capacity, and automatically complete the charging of the battery pack. Charging is completed, the test data through the RS232 interface directly upload to a PC or on-site data is transferred to the U disk; data processing software supporting the charge of data processing to generate a variety of charts and provide a scientific analysis of battery performance basis. 

 Second, the product features: 
 ※ crystal screen display, Chinese menu prompts, real-time display of all test data: charge current, charge voltage, charge time, charging capacity and temperature. 
 * Intelligent three-stage charging, real-time online polling of battery voltage, voltage, current, time and other parameters can be set to automatically complete the charging of the battery pack. 
 ※ monitoring functions: real-time display of each set of parameters (such as voltage, current, time, etc.). 
 Protection: by setting the charge capacity, charge and length parameters and automatic protection. 
 The tablet press to U disk data transfer application of storage technology, to solve the problem of large-capacity data storage. End-of-charge data transferred by the U disk or via the RS232 interface to upload computer background processing can automatically generate a variety of charts, battery performance at a glance. 
 ※ voltage, current display calibration correction: calibrate the battery pack voltage and current. 

 Third, the product features: 
 ? Advanced technology: machine switching power supply technology, smart charging technology, high reliability and adaptability to network fluctuation. 
 ? High stability: the switching power supply control chip imports of military-grade integrated circuits, stable and reliable, and extend battery life; forced air cooling, the load is automatically divided equally low failure rate and high reliability. 
 ? Using pulse width modulation technology, high efficiency, high power factor; low ripple factor, small interference to other equipment. 
 ? Charging characteristics: smart charging technology, the charging process without human intervention. Strict accordance with the curve of the battery charging feature charging, constant current → constant current limiting → trickle float "smart three-stage charging mode, so that each cell can quickly and fully fully charged to avoid charging, fully completed to automatic working state, without human duty. 






 ? A wide range of applicable batteries: charging current 10 percent - rated arbitrarily set without the impact of changes in the input AC voltage, during the constant current charging current to remain unchanged, without human adjustment.
