Highlights
Total Protection
STR series UPS provide maximum protection and power quality for mission critical loads, including data centres, industrial processes, telecommunications, and security and electro-medical systems.
STR is an ON LINE double conversion UPS (VFI SS 111 – IEC EN62040-3) with a transformer isolated inverter.
The Master MPS range includes three-phase input and single-phase output versions from 10 to 100 kVA, and three-phase input and output versions from 10 to 200 kVA.
All versions are provided with a 6-pulse thyristor-based rectifier, with or without optional harmonic filters. A 12-pulse thyristor-based rectifier is available on request for the 60 and 80 kVA versions with or without optional harmonic filters.
Easy Source
STR makes supplying the UPS from generator sets and MT/BT transformers simpler and more efficient, reducing power loss in the system and coils, correcting the power factor and eliminating current harmonics created by the loads supplied by the UPS.
In addition to this, the progressive rectifier start up (power walk-in) and the option to reduce battery charging currents, allow for a reduction in the input current uptake.
This means less demand on the source, which is particularly useful when the source is a generator set.
Flexibility
STR is suitable for a wide range of applications including IT and the most demanding industrial environments.
The UPS is suitable for power capacitive loads such as blade servers, from 0.9 leading to 0.8 lagging. With a broad range of accessories and options, complex configurations and system architectures can be achieved to guarantee maximum power availability and the option to add new UPS without interruption to existing installation
Battery Care System: Maximum Battery Care
Normally the batteries are kept charged by the rectifier; when mains power fails, the UPS uses this energy source to power the consumers. Proper battery care is therefore critical to ensuring correct UPS operation under emergency conditions. The SATRON UPS battery care system consists of a series of functions designed to optimise battery management and achieve the best performance and operating life possible.
STR is also compatible with different battery technologies: vented open lead acid, VRLA AGM, Gel, NiCd, Flywheels, Supercaps and Lithium

Advanced Communications
Maximum Reliability And Availability
Options
Allows two or more non-parallel UPS devices to remain synchronised even during mains power failure. The UGS also enables a SATRON UPS to be synchronised with another power source that is independent and of a different power rating.
Allows two groups of UPS to be connected in parallel whilst operating, in the event of maintenance (with no interruption to the output), using a power coupling switch.
Should one of the UPS in one of the parallel groups fail, it is automatically excluded.
The PSJ connects the remaining UPS, to the other parallel group via an external bypass, in order to continue to guarantee load redundancy.
Dual Bus Configuration
Solution to ensure redundancy up to the distribution of the power supply to the loads and improved STS operation
