Overview

The Xtreme Power E91 is a three-phase UPS series for critical loads, data centres, healthcare, industrial and infrastructure. We specify the right configuration from the E91 line, supply it, and install it turnkey across Canada. We carry every major brand, so we can compare the E91 against the alternatives on price, footprint and lead time.

Compact centralized three-phase

The E91 is a compact, centralized online double-conversion UPS (10 to 20 kVA (30 to 40 kVA on the sibling frame) at 208Y/120V) with the electronics and VRLA batteries in one cabinet, built for fixed-capacity sites that don't need a modular system. Its unity output power factor (kVA = kW) gives, per XPC, up to 25% more real load than typical 0.8-PF platforms at the same kVA. Efficiency runs up to 94% online and up to 98% in ECO mode (Energy Star 2.0), it rides through 110% for an hour, and it can be locked to 50 or 60 Hz as a frequency converter. Runtime extends from ~11 minutes internal to nearly two hours with external EBP09 cabinets. It's UL, cUL, FCC and TAA compliant (the cUL listing matters for Canadian sites) with a 4.3-inch colour touch display and an SNMP/relay card slot.

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 E91 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 E91 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.
