Specifying or deploying a Vertiv / Liebert EXL S1? We size it to your load and redundancy, supply it, install and commission it, and maintain it for life.

The Vertiv / Liebert EXL S1 is a three-phase UPS series for critical loads, data centres, healthcare, industrial and infrastructure. We specify the right configuration from the EXL S1 line, supply it, and install it turnkey across Canada. We carry every major brand, so we can compare the EXL S1 against the alternatives on price, footprint and lead time.
How a three phase double conversion UPS carries the load, and where the bypass sits.

The Liebert EXL S1 introduced Vertiv’s Dynamic Online mode, which reaches up to 99% efficiency with a 0 ms transfer from high-efficiency to inverter mode, against up to ~10 ms on legacy designs, so the inverter can take the load instantly and hold output within IEC 62040-3 Class 1. That removes the usual trade-off where classic ECO mode buys efficiency at the cost of protection. Vertiv frames three IEC operating modes, full double conversion (VFI), active filtering / high efficiency (VI) and maximum energy saving (VFD), and cites a 280+ MW Dynamic Online install base across colocation, cloud and industrial sites.

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 EXL S1 is one option we weigh on its merits, not the only answer.
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 EXL S1 units that are out of warranty or discontinued by the manufacturer.
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.
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.
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.
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.
Yes, UPS, power distribution, racks, batteries and the installation in one quote, coordinated with your electrical contractor.
Tell us the application and we will come back within one business day, sizing, the right system, install and a price. Three-phase installs usually need a licensed electrician, so let us know if you have one.
