Fuji Electric’s own Hybrid SiC-IGBT AT-NPC 3-Level Circuit (with RB-IGBT*) Redundant Fans Single Phase, Low-Voltage Power Capacitors on Input and Output High Efficiency Mode: Efficiency 99%

Fuji Electric’s own Hybrid SiC-IGBT

Our SiC-IGBT provides more durability and efficiency without added cost.

AT-NPC 3-Level Circuit (with RB-IGBT*)

Fuji Electric’s patented RB-IGBT reduces conductive losses and reactor losses in a 3-level (T-type) conversion circuit.

*Reverse Blocking IGBT

Redundant Fans

Truly redundant fans in UPM (UPS Power Module) so a fan failure does not send the UPS to bypass/

Single Phase, Low-Voltage Power Capacitors on Input and Output

  • Internal protective device against rupturing

  • Metalized polypropylene film capacitor, encased in epoxy resin, plastic case

  • Lighter than 7000WX, equally durable

  • Designed for the life of the UPS (15 years)

High Efficiency Mode: Efficiency 99%

  • Utility power (bypass) feeds load without using rectifier, inverter

  • Power factor improvement is performed by active filter operation

  • Battery charging is performed from the inverter side

  • In case of utility outage or voltage fluctuation, unit switches to battery supply, transition not to exceed 2 ms
