Two kinds of representative structures of modular type UPS

One kind is power modular type UPS. Power modular Rackmount UPS is composed of a rackmount and power module, the power module including traditional UPS rectifier, filter, charging, inverter and so on. But the static bypass and the part of the system monitor and display the same rackmount. Each module is independently controlled in parallel operation, and the display control module on the upper part of the cabinet is only used as a platform to switch the UPS host and network monitoring by the user. The rackmount modular uninterruptible power supply is composed of rackmount and single module composition, each module is equipped with the UPS and the control circuit, including rectifier, inverter, static bypass switch and auxiliary control circuit, CPU main control panel. Each UPS module has an independent management system. Relative to electronic technology and components development, two kinds of structure have their own advantages, also have very good representative products, provides the advanced distributed parallel technology, make the UPS system is not limited by the centralized control technology of reliability constraints, to avoid failure bottleneck, provides N + X parallel redundancy function modular parallel system.
