This series is an intelligent dedicated UPS (communication specific) power supply, which adopts intelligent microcomputer DSP control technology, advanced control theory, and mature and stable high-frequency UPS (communication specific) mode. It can quickly respond to changes in the external environment and provide uninterrupted high-quality AC output in real time.
Adopting advanced PWM+SPWM pulse width modulation technology, the output is a pure sine wave with stable frequency and voltage, noise filtering, and low distortion.
Advanced DC-AC electrical isolation technology, different from other pseudo isolation modes, truly achieves complete electrical isolation between DC and AC in all circuits, meets the isolation requirements of all application systems, and eliminates all possible interaction interference.
Equipped with power on self-test function, strong load capacity and good load compatibility; Built in bypass switch improves the continuity and reliability of UPS (communication specific) power supply.
It has the function of directly turning on the mains power, allowing users to bypass the mains power output to supply power to the load when there is no DC input; Allow to cut off DC and automatically switch to the mains bypass when turned on, without affecting the power supply of the load, making it convenient for maintenance and replacement of the battery.
Equipped with adaptive function for 50HZ/60HZ mains input, it can track and remember the mains input frequency and output the same frequency mode as the UPS (communication specific), enabling the input frequency range of the UPS (communication specific) to reach 44Hz~66Hz and output 50Hz or 60Hz, widely adapting to different power grids and equipment requirements.
Equipped with intelligent unmanned operation function, in the event of high or low DC voltage, power outage or other shutdown outputs, the DC voltage or power supply will return to normal, and the power supply will automatically resume output, especially suitable for unmanned communication base stations.
It has complete safety protection functions, including DC input anti reverse connection and DC input buffer protection, and comprehensive protection measures such as overvoltage, overload, short circuit, overheating, UPS (communication specific) faults, etc.
Adopting advanced anti backflow noise suppression technology, it does not interfere with other communication devices that share the DC screen. The AC input terminal adopts multiple filtering to eliminate interference from the mains power grid, meeting the requirements of the application system for the main AC power supply.
Provide two working modes, A and D, where:
- The A-type UPS (communication specific) power supply is in the mains output mode when there is mains power, and automatically switches to the UPS (communication specific) output when the mains power input fails.
- The D-type UPS (communication specific) power supply works normally in UPS (communication specific) output mode, and automatically switches to the mains bypass output when the DC input fails.
Equipped with rich LED/LCD status display and alarm signal display functions, providing a complete and user-friendly human-machine interface.
Provide 3 sets of passive dry nodes for DC input low voltage faults, AC input faults, and equipment fault alarms.
Provide standard RS232 communication interface, support real-time data communication function, and use monitoring software to monitor and manage the working status of UPS (communication specific) power supply in real time.
By connecting an external SNMP adapter, the UPS (communication specific) power supply can be connected to the internet, achieving the purpose of network monitoring and management.
