1. DIV series inverter adopts microcomputer CPU for intelligent control, and it has simple and reliable control circuit for high-speed response to changing environment;
2. DIV series inverter adopts SPWM technology to output pure sine wave which has stable frequency, stable voltage, low noise and low degree of distortion;
3. DIV series inverter has strong loading capacity, strong load adaptability, and built-in bypass switch to ensure continuous and stable power supply;
4. The DC input end of DIV series inverter adopts noise reduction technology to avoid interference with other communication equipments that share the same DC cabinet. The AC input end of DIV series inverter adopts multiple filtering technology to avoid interference from AC and meet the demand of application system for master AC power supply;
5. DIV series inverter is applicable to set AC or DC as master power supply (optional but only one):
a)with electric supply, AC as master power supply: remains AC output in case it is available and switches to DC output in case AC supply is interrupted;
b) with electric supply, DC as master power supply: remains DC output in case AC is available, and switches to AC output in case DC supply is interrupted;
6. DIV series inverter has scientific design, and it automatically switches to AC bypass in case DC supply is cut off in running status, which doesn’t affect power supply and facilitate the maintenance and replacement of storage battery;
7. DIV series inverter cuts off power supply in case of high/low battery voltage alarm or overload alarm, and resumes power supply when the battery voltage resumes normal status, therefore, DIV series inverter is quite applicable to unattended communication base station;
8. DIV series inverter has a LCD display, so that it is easy for the user to check the working status. The LCD display adopts 1602B, 122*32 dot matrix, silver white text against blue background;
9. DIV series inverter supports AC starting in case of DC supply is interrupted (optional);
10. DIV series inverter supports communication function and real-time monitoring function through monitoring software (optional);
11. DIV series inverter supports TCP/IP protocol, so that the user can utilize EtherCAT and monitoring software to achieve remote and real-time monitoring of working status (optional);
12. DIV series inverter has three groups of passive dry contacts to meet the emergencies of DC input failure, AC input failure or AC output failure (optional).
