Power Protection provided by the P90G-3000 Online UPS:

  • Power problems 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  • Unstable incoming power caused from outdated or faulty electrical wiring and or power distribution equipment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 P90G-3000 3kVA Online UPS 200V 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 P90G-3000 is a 3kVA true online double conversion uninterruptible power supply providing 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 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 P90G-3000 2700W Online UPS 200V 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. Under battery mode the 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.
