Product Description
Shenzhen supplies high-frequency vertical railway inverters/inverters
Zhilian Shengda’s series of high-frequency vertical inverters are targeted at communication systems, railway systems, The new generation of intelligent dedicated high-frequency inverter power supply is carefully developed and designed to meet the requirements of power systems to meet the requirements for high quality and high reliability of power supply in various application environments such as communications, railways, and electric power, and is suitable for all applications that are sensitive to power interference and require reliability. , purified uninterrupted sine wave AC output system.
Functions and features
Vertical inverter power supply
Industrial-specific load function is an intelligent dedicated inverter power supply using intelligent microcomputer control technology, advanced control theory and mature and stable high-frequency inverter The variable mode 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 is different from other pseudo-isolation modes to truly realize D and
complete electrical isolation in all loops to meet the isolation requirements of all application systems and eliminate all possible interactive 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, allowing the user to bypass the mains output to supply power to the load when there is no DC input. It allows the DC to be cut off and automatically switched to the mains bypass when the power is turned on, without affecting the power supply of the load. It is convenient for battery maintenance and replace.
Equipped with mains input/
Adaptive function 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 adaptable to different power grid and equipment needs.
Equipped with intelligent unattended function. When the DC voltage is too high or too low, the mains power fails, etc., the output is shut down and the power supply automatically recovers after the DC voltage or mains power returns to normal. It is especially suitable for unattended communication sites. .
Vertical inverter power supply
It has complete protection functions and has comprehensive protection measures such as DC input surge protection, overvoltage, overload, overtemperature, short circuit, inverter failure, etc.
Advanced backfeed noise suppression technology is used to prevent interference with other communication equipment sharing a DC screen. The AC input terminal uses multiple filters to eliminate interference from the mains power grid to meet the needs of application systems that require main AC power.
Vertical inverter power supply
Provides two working modes:
type and
type. Among them:
)
type inverter power supply is in the state when there is mains power. Mains output mode automatically switches to inverter output mode when the mains input fails.
)
type inverter power supply normally operates in the inverter output mode and automatically switches to the mains bypass output mode when the DC input fails.
It has rich D/
status display and alarm signal display functions to provide a complete and approachable human-machine operation interface.
Provide
sets of passive dry junctions for DC input low voltage fault, AC input fault, and equipment fault alarm respectively.
Vertical inverter power supply
Provide standard
communication interface to support real-time data communication function and use monitoring software to monitor and manage the working conditions of the inverter power supply in real time.
Through the external adapter
the inverter power supply can be connected to the Internet for the purpose of network monitoring and management.
