Data Centers & Critical Power Infrastructure
When Failure Points Cost Millions
Data center operators face an unforgiving reality: every minute of downtime costs an average of $9,000, and a single power quality issue can cascade into equipment failure, lost revenue, and damaged reputation. Whether you’re managing hyperscale facilities in Elk Grove Village, colocation spaces in downtown Chicago, or edge computing sites across the Midwest, the electrical infrastructure supporting your operation must perform flawlessly under continuous load.
We understand that specifying the right automatic transfer switch, selecting properly rated contactors for PDU applications, or sourcing compatible replacement parts for legacy UPS systems requires more than catalog lookups—it demands experience with how these systems actually perform in 24/7/365 operations.
We cross reference obsolete model to identify upgrath paths that maintain your existing footprint, breaker compatibility, and coordinated delivery during scheduled maintenance — avoiding costly emergency replacement scenarios.
- Automatic Transfer Switches (ATS) – open/closed transition, bypass-isolation
- Molded Case Circuit Breakers (MCCBs) – 15A to 1200
- A frames Miniature Circuit Breakers (MCBs) – DIN-rail and panel mount
When utility power fails, your ATS must detect the outage, signal generator startup, and transfer the load—all within seconds and without creating voltage transients that crash sensitive equipment. We supply Siemens and ABB ATS systems rated for data center duty cycles, including
- Open and closed transition transfer switches for different load types
- Bypass-isolation ATS configurations that allow maintenance without downtime
- Microprocessor-based controllers with remote monitoring capability
- Properly rated for both resistive and inductive loads in IT environments
UPS systems bridge the gap between utility loss and generator startup, but they’re only as reliable as their switching components, isolation contactors, and bypass circuitry.
- ABB and Siemens contactors rated for UPS switching duty
- Isolation switches and bypass mechanisms for UPS maintenance
- Input and output harmonic filtering components.
- Battery management system sensors and controls
Modern high-density racks can pull 20-30kW per cabinet, creating challenges for branch circuit protection, neutral-ground bonding, and current monitoring.
- Branch circuit protection (MCCBs, SPDs) rated for IT power quality
- Current transformers and power monitors for real-time load tracking
- Surge protection devices (SPDs) coordinated for cascaded protection schemes
- Panduit cable management and labeling systems for change management
Make sure you have a partner in redundancy and backup power systems.
- Surge Protective Devices (SPDs) – coordinated cascade protection
- Contactors & Motor Starters – UPS-duty rated, high cycle life
- Power Relays & Isolation Switches – load break and non-load break
Generator sets provide backup power, but the electrical components that control generator startup, load transfer, and paralleling determine whether the transition is seamless or catastrophic.
- Generator control panels with auto-start/stop sequencing
- Load shedding relays for non-critical loads
- Synchronization relays for paralleling multiple generators
- Fuel monitoring sensors and alarm systems
Switch mode power supplies in modern servers create harmonic currents that can overheat neutrals, cause nuisance breaker trips, and reduce equipment lifespan
- Voltage regulators and line conditioners
- Harmonic filtering reactors (5th and 7th harmonic mitigation)
- Passive and active harmonic filters for non-linear loads
- Isolation transformers for sensitive electronics
Data centers require precise environmental conditions—temperature, humidity, and airflow must stay within tight tolerances.
- Current Transformers (CTs) – revenue-grade and monitoring-grade
- Voltage & Current Transducers – analog and digital output
- Power Quality Meters – kWh, harmonics, power factor
- Phase Monitors & Sequence Relays – three-phase protection
- Temperature & Humidity Sensors – RTD, thermocouple, capacitive
- Building Automation Controllers – modular I/O, networked
- RTD and thermocouple sensors for hot/cold aisle monitoring
- Humidity sensors with 4-20mA or digital output
- Multi-zone temperature controllers for CRAC/CRAH units
- Alarm relays for over-temperature conditions
- Differential pressure sensors for raised floor plenum monitoring
- Airflow switches for cooling system verification
- Fan failure detection relays
- Building Management System (BMS) integration components
In a data center, proper cable management isn’t just about aesthetics—it’s about airflow optimization, rapid troubleshooting, and compliance with TIA-942 data center standards.
- Structured Cabling Systems (Panduit) – fiber, copper, hybrid
- Cable Tray & Runway Systems – mesh, ladder, solid-bottom
- Cable Identification & Labeling – heat shrink, wrap-around, adhesive
- Cable Ties & Fasteners – standard, heavy-duty, releasable
- Grommets & Cable Glands – strain relief, environmental sealing
- Fiber Optic Enclosures – splice trays, patch panels, breakout
During emergency troubleshooting, properly labled cables means the difference between minutes and hours long outage affecting customers.
- Structured cabling systems with pre-terminated fiber and copper
- Cable runway, basket tray, and overhead support systems
- Heat-shrink and wrap-around labels resistant to data center temperatures
- Color-coded cable ties and identification systems for power/data separation
- Lockable cable ties for secure physical layer access control
Lightening strikes and utility switching transients can destroy sensitive electronics. Proper surge protection requires a coordinated approach across service entrance, distribution panels, and equipment feeds.
- Ground Fault Relays – monitoring and alarm functions
- Safety Interlocks & Kirk Key Systems – mechanical interlocking
- Lockout/Tagout Devices – electrical isolation and verification
- Grounding Busbars & Lugs – copper and aluminum rated
- Arc Flash Labels & Calculation Services – NFPA 70E compliance support
We provide ABB and Siemens surge protective devices rated for data center applications, with coordination between stages.
- Service entrance SPDs: High-energy devices (Type 1) at the main switchboard
- Distribution panel SPDs: Medium-energy protection (Type 2) at sub-panels
- Equipment-level protection: Low-energy point-of-use devices (Type 3) at critical loads
- Single-point grounding systems for telecom equipment
- Grounding busbars and ground window kits
- Ground fault detection relays (not for circuit interruption, but for monitoring)
- Isolated ground receptacles and transformers where required
Ensure reliable power for your data center projects.
