0:00 What is the Toshiba G9000? What is the Toshiba G9000? It is Toshiba's online double-conversion three-phase UPS, in seven ratings from 100 kVA up, at 480 volts, three wire plus ground, on fifth-generation CSBTIGBT that Toshiba publishes as designed for UPS duty.

0:20 How does it scale? How does it scale? It runs stand-alone, or in parallel: up to four units in the 100 to 225 kVA models, or up to eight units in the 300 to 750 kVA models, with no special switchgear cabinets, which suits small to large data centres.

0:39 Which batteries does it take? Which batteries does it take? VRLA, NiCad, or Toshiba's own lithium-titanate oxide batteries, the chemistry Toshiba publishes for this range, so the battery choice follows the runtime target.

0:52 How efficient is it? How efficient is it? Up to 97 percent at 50 to 100 percent load, and above 94 percent down to 20 percent load, in true online double conversion, VFI, which suits parallel systems that run part-loaded. Those are Toshiba's published curves.

1:09 What about the input? What about the input? Input power factor is over 0.99, and the input window is plus 15 to minus 20 percent without drawing batteries. Toshiba publishes it as generator-friendly, so the genset can be sized tightly.

1:24 And sudden load changes? And sudden load changes? It accepts a load step from 0 to 100 percent without waveform distortion, one step from no load to full load. Monitoring runs through Toshiba's secure multi-protocol card.

1:37 Is it current? Is it current? Yes. Toshiba lists the G9000 as a current three-phase UPS, and backs it with a three-year onsite warranty.

1:46 Who is it for? Who is it for? Sites needing online protection across the 100 to 1,050 kVA range, from a single 100 kVA unit to eight in parallel, especially generator-backed sites that need tight genset sizing. If you are sizing one, request a quote at threephaseups.ca.

Maintenance visit checklist

What does a maintenance visit check on a Toshiba G9000?

2:12. Toshiba's own answer for the G9000: two Major PM visits per year at six-month intervals, each including battery maintenance and an offline inspection. The parts table sets the clocks: cooling fans at 5 years, electrolytic and AC filter capacitors at 15, control relays and contactors at 15, the PCB and control power supply at 15, the LCD at 10, fuses and thermal relays at 10. Battery end of life is 80 percent of nominal amp-hour capacity. Air filters use Toshiba-specified part numbers per frame. Source: Toshiba's G9000 manual 61480-018 Rev J, sections 7 and 9.

0:00 What does a maintenance visit check on a Toshiba G9000? What does a maintenance visit check on a Toshiba G9000? Toshiba's own answer: two major PM visits per year, at six-month intervals, and each one includes maintenance of the batteries and an offline inspection of the UPS.

0:15 What is on you between visits? What is on you between visits? The daily look is exterior only. Keep the room between 32 and 104 degrees Fahrenheit, at 30 to 90 percent humidity with no condensation, held near 77 degrees by air conditioning. Check fan noise. Check air-filter clogging and clean or wipe the filters. Check the LCD, the LE Ds, and the meter readings.

0:38 What does the visit replace? What does the visit replace? Toshiba's parts table gives the life expectancies: cooling fans at five years; electrolytic capacitors fifteen; AC filter capacitors fifteen; control relays, contactors, the PCB and the control power supply at fifteen; the LCD at ten; fuses and thermal relays at ten.

0:59 And the caveat? And the caveat? Toshiba's own: the recommended replacement interval varies with the operating environment.

1:06 What are the filters? What are the filters? The manual lists the part numbers per frame, 300 to 750 k V A, and says to use only air filters specified by Toshiba.

1:16 When do the batteries retire? When do the batteries retire? The manual says replacement is recommended once the capacity falls to 80 percent of the nominal rating or less.

1:25 And the record? And the record? Note any fault codes and call service. That record is what the visit starts from. Everything else, including breakers, power cabinets and batteries, is technician work. The manual calls for an offline inspection of the UPS, and battery work is technician only. The parts table sets the schedule: cooling fans at five years, capacitors at fifteen, the LCD and fuses at ten. The visit is where that schedule gets worked, not after the alarm.

Efficiency & generator friendliness

The G9000 is a 480 V, 3-wire plus ground, online double-conversion UPS from 100 to 1050 kVA on 5th-generation CSTBT IGBTs. It reaches up to 97% efficiency at 50 to 100% load and stays above 94% down to 20%, useful in N+1 parallel systems that run part-loaded. Input power factor is over 0.99 and the input window is +15%/−20% without drawing batteries, so it's generator-friendly and sizes the genset tightly; it accepts a 0 to 100% load step without waveform distortion. Parallel up to 4 units (100 to 225 kVA) or 8 units (300 to 750 kVA) with no separate switchgear cabinet, running VRLA or Toshiba SCiB lithium-titanate batteries.
