Power Range: 6 - 10 kVA

Guard Tower is the ideal solution for protecting mission-critical systems such as safety devices, telecommunications equipment and IT systems to ensure maximum power reliability. 

Guard Tower is designed and built using state-of-the-art technology and components to provide maximum protection to the powered loads with no impact on downstream systems and optimised energy savings. The series includes 6-10 kVA/kW single/single-phase output models with ON LINE double conversion technology (VFI): the load is powered continuously by the inverter which supplies a sinusoidal voltage, filtered and stabilised in terms of form and frequency.

Guard Tower

6-10 kVA/kW

Technical specifications of the model


  • Total microprocessor and DSP control.
  • Interruption-free static and manual bypass;
  • Specifications guaranteed up to 104 °F/40 °C (the components are designed to work at high temperatures and thus are subject to less stress at normal temperatures).

High quality output voltage

  • Even with non-linear loads (IT loads with a crest factor of up to 2.6:1);
  • High short circuit current on bypass;
  • High overload capacity: 150% by inverter (even with mains failure);
  • Filtered, stabilised and reliable voltage (double conversion ON LINE technology with filters for the suppression of atmospheric disturbances;
  • Power factor correction: UPS input power factor close to 1 and sinusoidal current uptake.

Simplified installation

  • Output terminal board;
  • Optional PDU;
  • Simplified positioning (built-in castors).

Advanced communications

GUARD TOWER offers maximum flexibility for integrations with any communication system.

  • Multiplatform communication for all operating systems and network environments, Powershield3 supervision and shut-down software for Windows, Mac OS X operating systems and other Unix operating systems;
  • RS232 serial port and opto-isolated contacts;
  • USB port;
  • Slot for TCP/IP, SNMP communication card;
  • Surge voltage let-through (max)—< 10V normal mode (L-N), < 0.5V common mode (N-G) when subjected to 6kV ANSI/IEEE C62.41 Cat. A;
  • Static switch—automatically transfers output from inverter to the isolated bypass source in the event of an overload or fault;
  • Surge voltage withstands capability—ANSI/IEEE C62.41 Category A & B, 6kV/200 & 500A, 100kHz ringwave.
