LIBRApro Double Conversion On-line UPS

The load is powered continuously by the inverter with a filtered, stabilised and regulated sinewave supply. The input and output EMI filters considerably increase the immunity of the load to mains disturbances and surges. Libra Pro provides maximum protection for vital 'mission-critical' networks, security applications (electro-medical) and industrial applications thanks to its outstanding mechanical and electrical design; isolation transformer on the inverter, extremely high short-circuit current, and sinusoidal absorption (THDi up to 5% with CLEAN version).

The system comes with reliable, filtered, stabilised and regulated sine wave output (double conversion on-line technology VFI according to EN50091-3 specifications with filters for atmospheric disturbance suppression). The system has high reliability: IGBT technology, full microprocessor control with no-break static and manual bypasses, extremely high short-circuit current to ensure compatibility with the most difficult applications (lighting, drives and industrial processes) and an isolation transformer on the inverter output. It provides minimum impact on the mains supply: up to 5% input current distortion to prevent resonance problems for upstream applications. The distortion is unaffected by impedance or frequency, and allows economies when sizing power sources such as isolation transformers or generators. It possesses a high level of diagnostics including an event log, states, measurements and alarms, available from the built-in LCD in several languages. Maximum reliability and power availability is assured as the UPS is enabled to operate up to 6 units for redundant (N+1) or parallel operation.  The system also has an EPO (Emergency Power Off) input for UPS shut-down using remote emergency button.
