Functional characteristics
1. high performance design:
All digital control has high accuracy, high real-time and high integration.
Advanced DSP+MCU control, and the intelligence level of the whole machine is higher.
2. reliability design:
The output isolation transformer is provided to prevent the impact of the output DC component on the load, reduce the output zero voltage, meet the requirements of the zero ground voltage in the special industry, and enhance the anti impact capacity of the output of the system.
Online double conversion structure design, protection device can work safely.
Strong adaptability of power input and strong adaptability of power grid.
Wide input voltage input frequency range, reduce battery discharge opportunity and extend battery life.
Input to have lightning protection surge design, effective protection equipment under special conditions.
3. humanized design:
The LCD display in Chinese / English LCD can display UPS's working status and parameter information in real time, so as to facilitate users' management of UPS.
By using LCD, the working parameters can be set flexibly.
The real-time battery capacity is displayed, which is easy to observe the working state of the battery.
• super network monitoring function, with RS232/RS485 output interface, easy to connect with computer, and achieve the right.
4. UPS monitoring;
Remote SNMP monitoring and management functions, providing real-time UPS information.
With DC starting function, without city electricity, UPS can start up normally; at the same time, it has the power of city electricity from starting, unmanned, perfect protection function:
• overload protection, over temperature protection, short circuit protection, output over voltage protection, real-time protection function, to ensure UPS reliability and load devices are not damaged.
• battery overcharge protection, over discharge protection, reverse protection, etc., to ensure that batteries are not damaged, and extend battery life
