Product Description:
Products of Zhilian Shengda Technology Co., Ltd. This series of rack-mounted high-frequency inverter power supply suppliers are targeted at communications
It is a new generation of intelligent dedicated high-frequency inverter power supply carefully developed and designed to meet the requirements of communication, railway and power systems. Everything is sensitive to power interference and requires a reliable, clean, uninterrupted sine wave AC output system.
Functions and features
The inverter power supply is an intelligent dedicated inverter power supply, using intelligent microcomputer control technology, advanced control theory and mature and stable high-frequency inverter mode, which can quickly Respond to changes in the external environment and provide uninterrupted high-quality communication output in real time.
Using advanced +
pulse width modulation technology, the output is a pure sine wave with stable frequency and voltage, filtered noise and low distortion.
Advanced
electrical isolation technology, different from other pseudo-isolation modes, truly achieves complete electrical isolation in all circuits, meets the isolation requirements of all application systems, and eliminates all possible interactions. interference.
Equipped with power-on self-test function, strong load capacity and good load compatibility. The built-in bypass switch improves the continuity and reliability of the inverter power supply.
It has the function of directly turning on the mains power, which allows the user to bypass the mains output to supply power to the load when there is no DC input. It allows the user to cut off the DC when the power is on and automatically switch to the mains bypass without affecting the power supply of the load. It is convenient Perform maintenance and replacement of batteries.
Equipped with mains input/
Adaptive function, it can track and memorize the mains input screen rate and inverter output the same frequency mode, so that the input frequency range of the inverter reaches ~ output
Or widely adapt to different power grid and equipment needs.
It has an intelligent unattended function. After the output is turned off when the DC voltage is too high or too low, or the mains power fails, the DC voltage or mains power returns to normal, and the power supply automatically recovers. It is especially suitable for unattended applications. On duty communications site.
The inverter power supply
has complete protection functions, including DC input surge protection, overvoltage, overload,
overtemperature, short circuit, inverter failure and other comprehensive protection measures.
Adopting advanced backfeed noise suppression technology, it does not interfere with other communication equipment sharing a DC screen. The AC input end uses multiple filters to eliminate interference from the mains power grid and meet the needs of application systems that require main AC power.
The inverter power supply
provides two working modes:
type and
type, among which:
)
type inverter power supply is in Mains output mode, automatically switches to inverter output mode when mains input fails.
B)
type inverter power supply normally works in the inverter output mode, and automatically switches to the mains bypass output mode when the DC input fails.
It has rich /
status display and alarm signal display functions, and provides a complete and approachable human-machine operation interface.
Provide
a set of passive dry junctions, respectively used for DC input low voltage fault, AC input fault, and equipment fault alarm.
The rack-mounted inverter
provides standard
communication interface, supports real-time data communication function, and uses monitoring software to monitor and manage the working condition of the inverter power supply in real time.
Through the external
adapter, the inverter power supply can be connected to the Internet to achieve the purpose of network monitoring and management.
