As part of the project for the construction of the second stage of the "Modular Data Processing Center" (MDPC), our company has supplied, installed, and commissioned six dynamic uninterruptible power supply systems (DUPS) CPM300, each with a power capacity of 300 kW/333 kVA, from the German manufacturer "Piller Germany GmbH & Co. KG".
The DUPS supplied by us are identical to the ones we installed in 2021 during the first stage of the MDPC construction. Over the course of a year of operation, the initial six dynamic uninterruptible power supply systems have performed exceptionally well, providing uninterruptible and high-quality power supply to the MDC regardless of the quality of the external power supply.
The DUPS operate in parallel mode, conserving energy through a kinetic energy storage device (module weighing over 2300 kg) rotating at a speed of 4750 revolutions per minute. In the event of a power outage, the storage device utilizes the stored energy to power the connected load until the diesel generators start running.
Unlike traditional static UPS systems, the DUPS do not use battery banks for energy storage and retention, which eliminates the need for infrastructure for battery placement, periodic replacement, and subsequent disposal.
The DUPS are housed in specially designed, manufactured, and installed fully insulated all-metal block-containers, designed to operate in external temperatures ranging from -50ºC to +50°C. These containers are equipped with their own automatic fire suppression systems, lighting, microclimate control systems, and lightning protection systems.
