The right UPS for the building, not the catalog.
Power infrastructure isn't generic. The right system depends on the load profile, the available footprint, the runtime expectations, and what the next ten years look like. We carry strong product lines from manufacturers who solve different parts of that puzzle — and we'll help you pick the one that fits, not the one we have a quota on.
Where power lives
Four contexts. Four different conversations.
The same word — "UPS" — covers wildly different products. The first job is figuring out which conversation we're actually having.
IDF & wiring closets
Single-phase, 1–5 kW, often at the limit of an existing 20A circuit. Lithium chemistry buys you footprint and a battery you don't replace mid-lifecycle.
5–20 kW, modular
Where most organizations actually live. Modular platforms let you scale capacity and runtime without buying it all up front, and Lithium has gone from premium to default.
Three-phase, redundant
10–600 kW per row, redundant configurations, integrated monitoring, hot-scalable. The decisions get more nuanced — and the cost of getting them wrong gets larger.
Process & PLC loads
Ferroresonant or isolated topologies for harsh electrical environments — the kind that destroy commodity UPS products. Different rules, different products.
Manufacturer · Single-phase modular
APC by Schneider ElectricAPC. Power, rack, and monitor — together.
APC's portfolio spans the full physical infrastructure stack — UPS, racks, PDUs, and EcoStruxure monitoring — designed to work together as a single environment. For projects that benefit from that integration, the whole conversation collapses into one vendor relationship, one set of monitoring tools, one service contract. We carry the full Smart-UPS family for single-phase loads and the Galaxy line for three-phase. Right now there's one product worth a longer conversation.

APC Smart-UPS Modular Ultra
Single-phase modular Lithium-ion · 5–20 kW · 9U or 16U rack
The Modular Ultra is APC's purpose-built replacement for the discontinued Symmetra LX — and the timing is the story. Symmetra LX hit end-of-life in December 2024. Anyone running one in production is on borrowed time.
The Modular Ultra keeps backwards-compatible electrical wiring with Symmetra LX (no rewire), upgrades chemistry to Lithium-ion (8–10 year battery life, no mid-cycle replacement), and runs 50% smaller and 60% lighter than the system it replaces. If you have a Symmetra LX in service today, this is a conversation worth having before the battery cycle decides for you.
Manufacturer · Single & three-phase
VertivVertiv. Mission-critical heritage.
Vertiv earned its reputation in environments where the cost of a power event is measured in serious money — telecom, healthcare, financial, federal. The Liebert family has been deployed at that bar globally for decades, and the modern lineup brings hot-scalable capacity, Lithium-ion options, and efficiency curves that hold up at the part-load percentages where most facilities actually run.
KAT-5 is a Vertiv channel partner with installation capability across the Liebert UPS family.

Vertiv Liebert APM2
Three-phase modular UPS · 30–600 kW · Lithium-ion option
The APM2 is Vertiv's modern modular three-phase platform — a direct descendent of the original APM that's been deployed in data centers globally for over a decade. APM2 brings flexibilities the original couldn't: hot-scalable capacity, wider efficiency curves at lower load percentages, and Lithium-ion battery options for sites that need the footprint and lifecycle benefits.
Where it fits: data center rows or facility-level UPS where you want headroom for growth without buying it all up front. Pairs naturally with Vertiv cooling at the row and perimeter levels.
Vertiv Liebert ITA2
Single-phase online UPS · 1–10 kVA · Tower or rack
The ITA2 is Vertiv's workhorse for 1–10 kVA single-phase applications — server rooms, network closets, distributed IT. Online double-conversion topology (load is always running on inverter-conditioned power, not just during a power event), tower or rack form factors, optional extended runtime battery cabinets.
Where it fits: bracket where you'd otherwise reach for a Smart-UPS or 9PX. The ITA2 is Vertiv's option in that range, and where Vertiv site-level service support is part of the standard, it's the obvious call.
Manufacturer · Pure-play UPS specialist
Xtreme Power ConversionXPCC. The capable alternative, increasingly the right one.
XPCC's roots run through Necedah, Wisconsin — the original home of Best Power and the Ferrups platform — which is why their UPS lineage feels familiar to anyone who's deployed Eaton or Powerware over the past 30 years. They're a pure-play UPS specialist (no chillers, no enclosures, no DCIM stack), focused exclusively on UPS and adjacent power conditioning across the topology range from 350 VA to 700 kVA. We carry their lineup alongside APC and Vertiv, and we recommend them more often than most procurement teams expect — particularly for Symmetra LX, Ferrups, and BladeUPS migrations where XPCC's successor products are purpose-built replacements with backwards-compatible architectures.
KAT-5 is an XPCC reseller with full installation and service capability.
XPCC TX91 Isolated Online UPS
Single-phase isolated online · 3.8–10 kVA · 240/120V
The TX91 is the modern replacement for the Eaton Ferrups (formerly Best Power Ferrups) — a ferroresonant transformer-based UPS that built its reputation in the 1980s as the gold standard for industrial and mission-critical applications where the load is harsh and the tolerance for downtime is zero.
911 dispatch centers. Marine vessels. Military installations. Factory PLCs. Eaton discontinued the Ferrups FE series in late 2024. The TX91 picks up where it leaves off, with the same isolated transformer topology and runtime-flexible architecture. If you have a Ferrups in production right now, this is your migration path.
XPCC Li90 & E91
Three-phase online UPS · 10–40 kVA (E91) · up to 30 kW Lithium (Li90)
The E91 is XPCC's standard three-phase platform for compact facility deployments — 10–40 kVA, online double-conversion, 208/120V. The Li90 takes the same capacity bracket and goes Lithium: 30 kW three-phase in a footprint 40–50% narrower and 30–40% lighter than traditional VRLA three-phase systems.
Where it fits: retrofit and edge deployments where floor loading and space matter. Same chemistry advantages as APC's Modular Ultra, applied at the three-phase tier.
XPCC J90 & P91Li
Single-phase Lithium-ion · 1–3 kVA · 1U rack or rack/tower
The J90 is XPCC's 1U rack Lithium-ion UPS for edge, industrial, and compact IT — LiFePO₄ chemistry, 10-year battery life, operates up to 50°C (122°F). The P91Li is the rack/tower variant in the same chemistry.
Both target the bracket where APC's Smart-UPS with Lithium-Ion lives, with similar value props (no mid-life battery replacement, lighter weight, longer warranty) and competitive pricing. Worth comparing side-by-side at quote time.
XPCC M90C Modular Three-Phase UPS
Three-phase modular · 5–24 kW (M90C-6S) · scales 5 kW at a time
The M90C is XPCC's competitive answer to Eaton's BladeUPS — a modular three-phase platform that scales 5 kW at a time, hot-swappable power modules, integrated maintenance bypass, and a frame factor designed for retrofit installations.
If you have a BladeUPS in production today, the M90C is the line to evaluate when the system reaches end of service. Comparable scalability, comparable modularity, fresh platform.
Category · NEC Class 4 power
PanduitFault Managed Power. Power at a distance.
Class 4 power is new — it appeared in the 2023 NEC, and most engineers are still meeting it for the first time. Panduit's Fault Managed Power System is a production-ready, deployment-proven Class 4 implementation, and it's worth understanding even if you don't have a project for it yet, because it solves problems traditional power topologies can't.
KAT-5 is a Panduit reseller. FMP is a recent addition to our portfolio.
Panduit FMP — Fault Managed Power System
NEC Class 4 · up to 2km transmission · standard structured cabling
Traditional electrical power has a topology problem. Low-voltage DC (PoE and similar) can't go very far before voltage drop kills it. High-voltage AC requires conduit, licensed electricians, and code-compliance work that makes "just power that camera over there" expensive. FMP fills the gap between them.
It delivers higher voltages (up to 450V) over standard structured cabling, with continuous millisecond-scale fault monitoring that shuts the circuit down before anyone could be exposed to dangerous current. Use cases: powering wireless APs, IP cameras, access control, edge compute, and remote switches at distances and locations conventional power can't reach economically.
If your project has wireless density, distributed switching, or remote loads at the edge of what PoE can deliver, FMP is worth a look.
What KAT-5 adds
The product is the easy part.
Anyone can resell a UPS. Specifying the right one — sized to your real load, suited to your building's electrical service, planned for your next refresh cycle, integrated with your monitoring — is a different job. That's the one we do. We've walked the buildings, balanced the loads, called the AHJ, supervised the install, and stayed for the post-install commissioning. We're the part that makes the project actually work.
Let's talk
