Data Center UPS Systems Built to Scale With You

Whether you're speccing a new data center UPS or replacing an aging one, we design for where your infrastructure is headed, not just where it is today. A data center's power needs rarely stay the same size for long — we build UPS systems that scale with you, from a single server room to a multi-site rollout, without forcing you to rip out and replace what you already have.

Built for scale — not just sold at scale

We equipped 12 shipping centers nationwide with scalable, modular UPS systems for supply chain operations — the same modular approach behind every data center system we design. When your infrastructure grows, your power protection should grow with it, not force a redesign.

Why Choose Custom Networks for Data Center Power

Why Choose Custom Networks for Data Center Power

Authorized APC by Schneider Electric distributor

We deploy Smart-UPS On-Line, Symmetra, and Galaxy platforms, with genuine hardware and full manufacturer warranty

In-house deployment team

Installation and ongoing support from people who know the system, not a subcontractor

34+ years in power and cooling

Since 1990, specializing in power and cooling since 1996

Where our data center systems get deployed

Enterprise server rooms

Centralized power protection for growing on-prem infrastructure

Multi-site rollouts

Scalable, modular UPS deployed across distributed locations (our approach behind a 12-site nationwide shipping center rollout)

Colocation and hosted environments

Redundant power built to meet uptime commitments

Backup and disaster recovery infrastructure

Power protection for the systems that need to survive an outage, not just ride through one

Online vs. Line-Interactive: Which UPS Type Does Your Data Center Need?

Line-Interactive UPS

Line-interactive UPS systems regulate voltage without fully converting incoming power, making them efficient and cost-effective for environments with relatively stable power. They're a strong fit for server rooms and smaller data center footprints where budget and efficiency matter as much as absolute power purity.

Online Double-Conversion

Online (double-conversion) UPS systems fully convert incoming AC power to DC and back to AC, providing continuous, regulated power with zero transfer time. This is the standard for larger data centers and mission-critical infrastructure where even a momentary voltage fluctuation is unacceptable.

We help you determine which makes sense for your actual load and risk tolerance — not just sell you the more expensive option by default.

Beyond the UPS: Full Power Infrastructure

A UPS rarely stands alone in a real data center deployment. We also design around:

Redundancy (N, N+1, 2N)

How much spare capacity your system carries so a single unit failing doesn't take down your infrastructure. Which level makes sense depends on how much downtime your operation can actually tolerate.

Battery autonomy

How long your system runs on battery alone before generator handoff or graceful shutdown, sized to your real infrastructure, not a default number.

PDU integration

Power distribution planned alongside the UPS itself, not bolted on afterward.

Maintenance bypass

The ability to service or replace a UPS without powering down the load it protects, using a maintenance bypass panel — a real product line we carry, not just a concept.

Questions

Line-interactive systems regulate voltage without fully converting power, making them efficient for stable environments. Online double-conversion systems fully convert incoming power, providing continuous regulation with zero transfer time — the standard for larger, mission-critical data centers.

Three-phase systems are typically needed once your data center's load exceeds what a single-phase system can efficiently support — usually in larger server rooms and full data center deployments rather than a small server closet. We size this based on your actual equipment inventory, not a general rule of thumb.

Yes — this is the core of a modular UPS approach. Instead of buying for five years of projected growth today, you install what you need now and add battery or power modules as your load actually grows.

It depends on whether you're bridging to a generator, riding out short utility blips, or need extended runtime for a full graceful shutdown. Most data center deployments are sized for enough runtime to reach generator handoff, with extended battery options available for environments without one.

Redundant (N+1) configurations run additional UPS capacity beyond what's strictly needed, so a single unit failing doesn't take down the whole system. Whether this makes sense depends on how critical continuous uptime is to your operation.
