Toshiba · G9400Toshiba G9400 Three-Phase UPS

Overview

The Toshiba G9400 is a three-phase UPS series for critical loads, data centres, healthcare, industrial and infrastructure. We specify the right configuration from the G9400 line, supply it, and install it turnkey across Canada. We carry every major brand, so we can compare the G9400 against the alternatives on price, footprint and lead time.

How a three phase double conversion UPS carries the load, and where the bypass sits.

Specifications

Efficiency & module architecture

The G9400 is Toshiba's megawatt UPS, 1200, 1600 and 2000 kVA at 480 V, built from 400 kW parallel power modules on Gen-7 CSTBT IGBTs. It holds about 97% online efficiency across the load range in a small footprint. The parallel-module design is inherently redundant: if a module faults, the rest stay online in double conversion as long as the load is within their capacity, instead of dropping the whole unit to bypass. Up to six systems parallel for capacity or N+x redundancy.

Isolation, fault tolerance & hibernate

Each module carries a DC isolation contactor (CB2) as standard (many competitors make it an option) so the UPS can take a single module offline on a fan failure while the others keep supplying double-conversion power, and it meets the UL 1778 EPO isolation requirement without external relay schemes. 100 kAIC fuses are standard in the static bypass. A selectable High Efficiency Hibernate mode rests modules below ~50% load for up to ~3% more system efficiency, rotating them so they age evenly.

Sizing, redundancy and custom builds

We engineer the solution: load and growth analysis, redundancy (N, N+1, 2N), runtime and battery sizing, paralleling and switchgear, and custom configurations where the standard catalogue doesn't fit. Because we supply every major brand, the G9400 is one option we weigh on its merits, not the only answer.

Supply, install and lifecycle

We deliver, install and commission the system on site (coordinated with your electrical contractor), then keep it running with preventive maintenance, battery replacement and emergency support, including G9400 units that are out of warranty or discontinued by the manufacturer.

Common questions

Can you replace an old or discontinued unit with a different brand?

Yes, that's most of what we do. Send the model and part number you have (any brand, even end-of-life) and we cross-reference an equivalent that matches the load and footprint. If the original is back-ordered, we propose an in-stock unit that ships sooner.

Do you replace just the batteries, or the whole UPS?

Whichever is the better value. A battery replacement (sometimes with an added cabinet for more runtime) often restores full protection at a fraction of a new system. We need your exact model and variant to quote it accurately.

What are the lead times?

It depends on the model and stock. When the original has a long lead time, we usually propose an equivalent we can ship sooner so the load isn't left exposed. Tell us your timeline in the quote.

Do you install it, and across Canada?

Yes, we supply, install and commission the system anywhere in Canada, coordinated with your electrician, and maintain it afterward: preventive maintenance, batteries, emergency support and remote monitoring, on a single unit or a multi-site fleet.

Can you quote a complete system, not just the UPS?

Yes, UPS, power distribution, racks, batteries and the installation in one quote, coordinated with your electrical contractor.
