UPS

Uninterruptible Power Supply (UPS) Systems provides critical protection for data centers and telecommunication equipment in mission critical applications, serving as a source of backup power in the event of a power outage。 Uninterruptible power supply, also called uninterruptible power source, protects your data when you need it most。 The cost of downtime can be catastrophic to financial institutions, data companies, hospitals and other facilities—not to mention the customers they serve。 Fuji Electric’s high-efficiency UPS Systems provide our customers with a lower total cost of ownership and the peace of mind they need。

When it Matters Most, Fuji Electric UPS Power Protection is the Only Option.

Fuji Electric provides complete solutions for the protection of valuable data in critical applications, including our reliable and efficient uninterruptible power supplies。

  • 1。 Please provide a brief comment on a single fan failure in a UPM.
     

    Each fan has a speed alarm. When any one alarm is detected, UPS will display "CAUTION" on LCD, and store a log "FAN ERROR". UPM continues running.

  • 2. Is an alarm produced for a single fan failure?
     

    No, it is not。 Only one type of caution message is displayed。 Please visually check it because you do not know which fan has failed。

  • 3. It looks like there are 3 fan power supplies and each power supply runs 2 fans. (6 fans total)
     

    Yes, on the top. Fuji has verified a single power supply failure. That means that 2 fans failure simulated.

  • 4. What would cause the UPM to turn off? (fan related)
     

    UPS will continue running until IGBT thermal sensor operates (rectifier, inverter or chopper).

  • 5. Please provide a brief comment on a single fan failure in a CTR-M.
     

    Each fan has a speed alarm. When any one alarm is detected, UPS will display "CAUTION" on LCD, and store a log "CTR FAN ERROR". CTR-M continues running.

  • 6。 Is an alarm produced for a single fan failure?
     

    No, it is not。 Only one type of caution message is displayed。 Please visually check it because you do not know which fan has failed。

  • 7. It looks like there are 3 fan power supplies and each power supply runs 2 fans。 (6 fans total)
     

    Yes, 4 fans on the top and 2 fans on the front for SCR. Fuji has verified a single power supply failure. That means that 2 fans failure simulated.

  • 8. Are the 2 fans in the front of the cabinet on the SCR heatsink fed from the same power supply?
     

    Yes。 2 fans are connected to one power supply。 And 3 power supplies are connected to one control transformer。

  • 9. What would cause the CTR-M to turn off (fan related, Open the bypass)?
     

    It depends on the thermal sensor mounted near SCR. When the thermal sensor operates, stop the SCR gate drive. Then, UPS will display "WARNING" on LCD, and store a log "TEMP ALARM (STS)".
    In the case of the parallel redundant UPS, the UPS that detects the abnormal temperature is disconnected (parallel-off). And the normal UPS(s) continues to supply power to the critical load.
