Protect 3.M 2.0

modular ups system

Uninterruptible Power Supply


20 –120kVA power supply

Networks, workstations, intranet and internet servers, telecommunications applications and other company applications must be permanently available. AEG Protect 3.M 2.0 is the modular UPS solution for IT and telecommunications. Modern data centers require the highest levels of efficiency, reliability and flexibility.

Protect 3.M 2.0 provides a technically convincing and reliable solution to this requirement that can be modularly adapted to any increasing power demand.

An extension can be made at any time during operation. The flexible redundancy concept ensures a steady power supply to any connected devices.

Lower operating costs for energy and cooling with high efficiency and fast module replacement in the event of power failure, reduce operational costs and ensure an optimal price vs. performance ratio for the Protect 3.M 2.0 UPS solution.

Power outages can lead to significant financial loss

Almost all labor and production processes today are based on high capacity data and IT infrastructure. Power outages or voltage fluctuations that lead to systems failure end almost always with disrupted operations, loss of production and, at worst, irretrievable data loss.

Your important IT infrastructure must be permanently available and protected against power disturbances of all kinds. Through the use of VFI (conversion) technology, Protect 3.M 2.0 reliably protects your systems against power outages and network disruptions and ensures the value of your business.

Modularity provides safety reserves and flexibility

Protect 3.M 2.0 is an uninterruptible power supply of the highest reliability.

With increasing demands on performance, the compact modular design adapts

the permitted UPS power according to your current power needs. This can be done without additional installation costs since the power modules can be easily inserted and are automatically recognized by the system (“hot swappable”). No additional connections are required for this operation.

Dynamic redundancy

An automatic load balancing to all modules within an appropriately designed system delivers N+x redundancy without the requirement for any configuration changes or increases to load capacity.

High efficiency lowers operating costs and CO2 emissions

Protect 3.M 2.0 is based on high efficiency IGBT technology. This provides an efficiency of up to 95 %

in double conversion mode. With a 35 % loading, the UPS still maintains an efficiency of 94 %. In addition to the lowering of power loss unwanted generation of heat is also reduced, thereby reducing air conditioning requirements. All of this leads

to significant cost savings and a reduction in CO2 emissions.

Input power factor 1.0

100 % active power from the UPS reduces the generator specification and consequent installation cost increases.

Battery Management

Each UPS power module contains its own battery charger with intelligent charging electronics. These can be adapted to the battery in use and facilitate the use of vendor independent standard batteries.

A temperature compensated charging curve ensures

an optimum charging regime. Automatic testing informs you of the charging state of charge and when charging will be complete.
