Product description

Features of the T90 10kVA Parallel Tower UPS include:

The T90 10kVA Parallel Tower UPS is designed for high density critical loads, delivering industry leading efficiency and scalability.  The T90 can be configured for online or ECO mode operation for efficiency of up to 97%.

Optional redundant and parallel UPS configurations allow complete serviceability and high reliability.  Should an individual UPS require maintenance, the UPS is automatically taken offline via internal bypass.  A notification is provided to the user from the LCD display and an audible alarm. The failed UPS module may be serviced or replaced without the connected load having to be powered down.

Power Protection offered by the T90 UPS:

  • Power conditions such as electrical surges and sags
  • Total loss of electrical power or hard power “re-boots”
  • Unstable incoming power caused from outdated or faulty electrical wiring and or power distribution equipment
  • Harmonic interference from neighboring “high power draw” equipment
  • Severe weather events such as lighting storms, ice and snow storms and downed power lines
  • Unstable power generation from local utilities or on-site generation

Wide Power Input

The T90 10000VA Parallel Tower 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

Double Conversion Technology

Double Conversion Technology

The T90 10kVA 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 T90 10kVA 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 during repair or module replacement.

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.
