New modular version of our transformer-free range specifically designed for industrial applications.

Building on the success of Riello UPS’s third generation of transformer-free solutions – the Sentryum – we’ve developed this new modular UPS series to ensure power continuity in settings such as factories and processing plants that are prone to harsh environmental conditions.

Sentryum Rack is available as either a 20 kVA standalone rackmount UPS that fits in standard 19-inch server racks or a modular solution that can be scaled up to a maximum capacity of 160 kVA. Each cabinet in the modular version can hold up to 3 x 20 kVA modules, offering users “pay as you grow” scalability.

Its advanced design ensures that all the power connections (input, output, batteries) are completely separate and isolated from the communication signal connections, thus removing the possibility of any potential disturbance from the supply network, which in industrial environments is often distributed and prone to problems.

The Sentryum Rack incorporates many of the characteristics of the already-popular Sentryum range:

  • Proven performance: up to 96.3% UPS efficiency in online mode whilst ensuring unity power (kW = kVA)
  • Quality power: delivers power factor correction upstream of the UPS to reduce harmonics (<1% at resistive load and <1.5% at non-linear load)
  • Maximum protection: handles short circuits (i.e. 150% for 300 msec) and overloads (i.e. 150% for 1 minute), meaning it can deal with sudden peaks without transferring the critical load to bypass
  • User-friendly: Large colour touchscreen display panel and an intuitive LED status indicator that changes colour depending on the UPS’s current status
