Product description

Features of the TX90 2000VA Isolated Online UPS  include:

The TX90 2000VA Isolated online UPS provides the cleanest power in the most demanding conditions. The TX90 galvanic isolation transformer prevents common mode noise which is left exposed by typical transformer-less online designs.

Galvanic isolation keeps the electrical output from the UPS physically isolated from input power coming into the UPS.  Power isolation is achieved by using isolation transformer.  No output electrical wiring comes in contact with the input power cabling.

Wide Power Input

TX90 worldwide input feature allows connection to just about any power source.  This feature covers voltages from 88V to 288V and frequencies from 40Hz to 70Hz. 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 uninterruptible power supply. 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 TX90 2kVA Isolated Online UPS utilizes the Double Conversion UPS topology.  This along with galvanic isolation provides the ultimate in clean and stable electrical power.

Incoming AC 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 waveform output providing near perfect electrical power for connected equipment.

To ensure 7/24 up time the true online double conversion UPS topology utilizes a static “bypass switch” within its circuity design. If the TX90 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.
