Wide Power Input

The T91 3kVA Tower Online UPS supports incoming wide AC power input. The automatic voltage regulator (AVR), protects the UPS and connected equipment from adverse voltage conditions. This wide AC input capability can offer sag and surge protection without engaging the backup batteries of the UPS. This will reduce the stress on connected critical equipment and extends the battery life of the UPS.

Double Conversion Topology

The T91 3kVA Tower UPS is a true online double conversion uninterruptible power supply.   Incoming AC utility power is fed to the UPS’ rectifier converting it from AC to DC power. The converted DC power routes to a battery charging circuit and to the inverter for conversion back to AC power. The resulting “double converted” electrical power is pure sine wave output providing near perfect electrical power for connected equipment.

To ensure 7/24 up time the double conversion UPS topology utilizes a static “bypass switch” within its circuity design. If the T91 3kVA tower UPS detects a system failure, audible alarms will sound as the bypass switch is engages. This routes power around the failed UPS and ensures critical load power to target equipment.  This very important feature allows for 100% up time for critical equipment while the UPS can be repaired or replaced.

In the event of total power failure, the UPS will power off the rectifier when the loss of power is detected. The UPS’ internal backup batteries will continue to supply DC power to the inverter. There is no transfer time as the transition to battery power is instantaneous. This feature provides true uninterruptible power to mission critical equipment.
