K&K Critical Infrastructure
Critical Power & Low-Voltage Field Services

Clean DC power, UPS maintenance, and precision low-voltage field engineering.

K&K Critical Infrastructure keeps facility power reliable and connected systems operating without interruption. We handle UPS maintenance and battery refreshes in data rooms, build out structured cabling pathways, and wire custom 12V harnesses for commercial fleets and mobile equipment.

Core Disciplines

Where We Work: Data Room to Mobile Fleet

From commercial facility electrical closets to specialty vehicle consoles, we build and maintain the low-voltage and DC infrastructure that sensitive hardware depends on.

Critical Power & Backups

UPS & Battery Plants

Preventative maintenance, string impedance testing, and modular battery replacements across three-phase and single-phase backup systems. We inspect capacitors, verify static transfer bypasses, and isolate inverter faults before they cause an outage.

  • • Battery cell testing & scheduled replacements
  • • Thermal scanning & capacitor life tracking
  • • Energized startup & commissioning checks
Facility Infrastructure

Structured Cabling & Pathways

Clean, documented low-voltage builds for telecommunications closets and equipment rooms. We run Cat6A copper, patch fiber backbones, mount racks, and label every run so your team never has to trace unmapped cables during an incident.

  • • Cat6A & fiber optic termination and testing
  • • Server rack buildouts, cable trays & patch panels
  • • Complete cable labeling and run-sheet documentation
12V Mobile Systems

Auxiliary DC & Fleet Electronics

Specialized 12V power distribution and clean harness builds for work trucks, utility vehicles, and mobile operations. We integrate telematics, secondary battery isolators, DC-DC chargers, and CAN-bus interfaces without tapping into factory wiring haphazardly.

  • • Dual-battery setups, inverters & DC-DC chargers
  • • Telematics, GPS tracking & camera systems
  • • Hand-built, loom-protected custom harnesses
Field Delivery

How We Execute on Site

No guesswork, no messy cabinet rat's nests, and no cut corners. We treat every job like the site's uptime depends on it.

01

Startup, Commissioning & Cutover

Whether bringing a new UPS online or integrating aftermarket telematics across a fleet, we verify voltages, test auxiliary control circuits, and validate proper operation before handing the keys back.

02

Preventative Maintenance & Inspections

Regular checks keep equipment running when utility power drops. We use calibrated FLIR thermal imagers to spot loose lugs, take internal cell resistance readings, inspect cooling fans, and clean out accumulated dust.

03

Methodical Troubleshooting

When a system drops offline, we troubleshoot down to the component level using multimeters, oscilloscopes, and signal testers—identifying bad boards, failed relays, blown fuses, or grounding faults before replacing expensive parts.

04

Turnkey 12V Electrical Harnessing

We build our low-voltage looms with proper crimps, heat shrink, braided split tubing, and dedicated fused distribution blocks. We don't use scotch locks or vampire taps that compromise factory wiring harnesses.

Field Discipline

Workmanship & Safety Standards

We work around live panels, critical battery banks, and vehicle electrical systems. Strict adherence to safety codes and installation discipline protects both personnel and equipment.

Standard / Domain Field Approach Impact on Your Facility
Electrical Safety & Arc Flash NFPA 70E compliance, proper PPE, strict Lockout/Tagout (LOTO), and insulated tools for all hot battery string maintenance. Zero-incident field execution in mission-critical environments.
Low-Voltage Cable Plant ANSI/TIA-568 compliance, correct bend radius maintenance, clean strain relief, and calibrated Fluke cable certification. Clean network data throughput and straightforward cable tracing.
12V DC Vehicle Integration Solderless marine-grade crimps, adhesive-lined heat shrink, correct wire gauges, and dedicated fuse block isolation. Protects sensitive factory ECUs from electrical noise and parasitic battery draw.
Testing & Documentation Digital reports with thermal photos, individual battery cell voltage/impedance readings, and clear corrective recommendations. Provides facility managers with an audit-ready maintenance log.
