Compact 3-phase UPS designed for critical applications

Optimising costs and space with uncompromised power protection, Protect Plus S300 range is the solution of choice to protect critical loads for small and medium applications where low power consumption, easy maintenance and floor space are important considerations.

Protect Plus S300 is based on a highly efficient transformer-less double conversion technology. AC/AC efficiency values of the system are close to 96% in operational conditions in double conversion and up to 98% in Eco Mode. The system is ensuring the lowest level of operational expenditure on the market in its category. Protect Plus S300 has a very low Total Cost of Ownership (TCO).

The system has been designed to respond to all major concerns of facility or data and IT managers. Protect Plus S300 thus provides enhanced power protection in the most compact formats currently available saving valuable floor space for operations. Depending on the power range, the system footprint is 20-50% less than the same capacity UPS of the former generation. Protect Plus S300 can be equipped with integrated batteries or isolation transformer (for total galvanic isolation) up to 80kVA

Protect Plus S300 is a suitable power protection for a wide range of critical infrastructure and assets thanks to a wide range of options which encompasses load synchronisation tool, top cable entry, degree protection up to IP41, battery temperature probes as well as all connectivity devices (SNMP, Modbus, RS232). As the system can cope with tough environment in a very compact footprint, it’s a suitable power protection for IIoT applications.

Easy to install and operate, Protect Plus S300 is also easy to maintain with its front access. Up to eight units can be installed in parallel connection allowing to fit a wide range of capacity, N+1 redundancy and a wide range of autonomy requirement.
