Features
Modular design
The system adopts the modular design of standard units, which is convenient for maintenance and replacement, and can realize the configuration of multiple capacity through series or parallel modules
Duplicated configuration
Multiple bypass functions are provided, including electronic switch bypass (1ms), zero level bypass (1ms) of the inverter unit, fast mechanical switch bypass (3ms) and mechanical switch bypass (60ms). When there is an abnormality in DVR body, various fast bypass methods do not affect the normal power supply of the load.
Intelligent self-check
The DVR is in standby state for a long time, and it has intelligent self-check function, which automatically determines whether the core inverter unit in the DVR is in normal state, thus improving the reliability of the equipment.
Fast compensation
Low voltage detection technology based on voltage variation and rapid switching compensation technology are adopted. Low-voltage fault detection can be completed within 500us, the voltage can be compensated to the normal range within 2ms, and the total time from voltage incline to compensation completion is <3ms.
