About this UPS
APC / Schneider Electric Easy UPS 3S three-phase UPS — series hub. The Easy UPS 3S is Schneider Electric's straightforward three-phase tower range — 10, 20, 30 and 40 kVA of double-conversion protection engineered for value: robust electrics, simple commissioning, and a price point that undercuts the premium Galaxy lines. For a server room or plant floor that needs dependable three-phase kVA without engineering exotica, this is the range to price first. Turnkey supply: equipment, freight, licensed installation, batteries and commissioning in one quote — request yours, call 438-881-3363, or compare families in the three-phase UPS guide.

Where the Easy UPS 3S fits
How the Easy UPS 3S compares
The value gateway to three-phase: the lowest cost per kVA in the stocked Schneider stable, with a parallel-bypass trick that buys N+1 for far less than a premium platform. Undecided between families? Start from the three-phase UPS family guide.
Runtime & expansion — batteries, cabinets, bypass
Runtime scales with the E3SXR7 modular battery cabinet (stackable strings), and the parallel bypass panel unlocks the range's quiet superpower: paralleling up to three units for N+1 redundancy or triple capacity — Galaxy-style resilience at Easy UPS pricing.
- E3SXR7 modular battery cabinet — in stock — stackable runtime strings, 208 V
- Parallel maintenance bypass panel (3 units, 10–40 kVA) — in stock — N+1 or capacity paralleling + hitless service
- Additional battery cabinets — combined for longer runtime, quoted per target (quote it)
Turnkey: from quote to running system
- Tell us the requirement — model or just load, runtime and site details.
- One configured quote — UPS, batteries/cabinets, bypass, freight, installation and commissioning together.
- We do the hard work — logistics, rigging, licensed electricians, startup, and preventive maintenance afterward. Replacing equipment? We buy back working units.
Common questions
How does the Easy UPS 3S compare to the Galaxy lines?
Same double-conversion protection philosophy, simpler feature set, significantly lower price per kVA. Galaxy buys you higher efficiency modes, deeper monitoring and wider voltage windows; the Easy UPS 3S wins when the requirement is solid three-phase protection at the best capital cost.
Can Easy UPS 3S units run in parallel?
Yes — with the stocked parallel maintenance bypass panel, up to three units share a load for extra capacity or N+1 redundancy, and any unit can be isolated for service without dropping the load.
How is runtime extended?
The E3SXR7 modular battery cabinet adds stackable battery strings; multiple cabinets combine for longer holds. Send your load and target minutes and we return the configuration.
Is this range serviceable long-term?
It's a current Schneider Electric range with standard battery modules and spares availability, and we support it with batteries, bypass hardware and preventive maintenance after the sale.
How do pricing and lead time work on three-phase systems?
Three-phase systems are quoted, not carted: pricing depends on configuration, batteries, freight class and installation scope. Send the requirement and you get a firm, itemized quote — and honest availability for each option before you commit.
Do you supply and install outside major cities?
Yes — supply, freight and installation are coordinated wherever the site is, through our network of licensed electricians and riggers. Remote and industrial sites are quoted with site logistics included.

Before you order
How do I know this UPS will run my equipment?
Add up the wattage draw of every device you'll plug in (servers, switches, monitors). The UPS's wattage rating — not VA — is the number that matters. Aim for the UPS to run at 60–70% of capacity at full load: this gives headroom for inrush current and a meaningful runtime margin. Email us your equipment list; we'll respond within one business day with sizing guidance.
What's covered by the warranty, and how long does it last?
New units carry the warranty coverage stated by the manufacturer; see the product listing or manufacturer documentation for the applicable terms. Refurbished units are covered by the 1-year UPSPLUSBATTERY warranty handled in Canada.
Can I extend runtime beyond what's shown above?
Many Smart-UPS-class models accept an external battery pack (XBP) connected to the rear battery port. If this UPS shows "Extended Runtime Capable: Yes" in the spec grid above, an XBP is supported. Compatible XBPs and the runtime gain they deliver vary by model — contact us if you don't see the right XBP in our catalogue.
