Uninterruptible power supply SNR-UPS-ONM-300-50SMX33, on-line, 300kVA, 380-415VAC, 480VDC, non batteries

The chassis of the modular uninterruptible power supply 300 kVA/300 kW SM series. The chassis accommodates up to 6 modules with a capacity of 50 kVA (50 kVA power modulesare purchased separately)

The modular online UPS of the SM series is designed to protect three-phase power supply systems of servers, data centers, industrial and medical equipment from power outages, voltage and frequency fluctuations and distortions, pulse, and high-frequency interference.

Modular UPS are suitable for a fast-growing business: their architecture allows you to expand the configuration as the business grows up to 300 kVA. This design of the UPS allows you to provide redundancy or flexible power build-up.

Modular uninterruptible power supplies of the SM series combine modern three-level technologies of IGBT rectifiers (bipolar transistors with an isolated gate) with the control logic of DSP (digital signal processors). With a high input power factor, low THDi (the total value of the nonlinear distortion coefficient), and high system efficiency, these devices can work with any type of load. The modular design ensures the reliable and stable operation of critical equipment.

Each power module is hot-swappable, which makes it easy to increase power and simplifies system maintenance. Independent control of each module eliminates the risks associated with failure due to the failure of one element. In case of failure or disconnection of one module, the system continues to operate and provides an uninterrupted power supply, guaranteeing high reliability and protection.

The control and display panel is located on the front panel of the UPS. The operator can control the UPS and monitor all measured parameters with this LCD panel.

An informative Russian-language display will allow the operator to control the UPS and monitor all measured parameters, monitor the status of the UPS and batteries, and view event logs and alarms.

The UPS page includes the header field, information area, version, operation status, and submenu

The mini-diagram schematically shows the current flow paths and the current operating mode of the UPS. The green color of the rectangles means the normal operation of the block, the white color means the absence of the block, and the red color indicates the absence of the block or its failure.

The Module menu displays all comprehensive information about the status of power modules. Independent control of each module eliminates the risks associated with system failure due to the failure of one element

The user can view output voltage, current, and bypass voltage graphs by tapping the corresponding icons on the left side of the page. Graphs can be scaled.
