Equipment for facilities that cannot go down.
Access represents the manufacturers behind critical power, thermal management and IT infrastructure — and installs, commissions and services what we sell. Browse by category, or start from the line card.
Uninterruptible Power Supplies
UPS systems from single-rack to multi-megawatt — sized, installed and maintained so the load never sees the blip.
- Fixed capacity single phase
- Centralized, modular single phase
- Data center and facility 3-phase
- Battery and flywheel energy storage
Generators & Transfer Switches
Standby generation and the transfer equipment that decides whether the facility rides through an outage.
- Diesel standby generators
- Natural gas and bi-fuel generators
- Automatic transfer switches
- Static and static bus transfer switches
Busway & Powerbars
Overhead and modular busway that lets a data hall change shape without an electrician rebuilding the branch circuits.
- Busbar and BusPlug
- Modular busway
- Overhead powerbars
- High-power bar
Power Distribution
PDUs, remote power panels and packaged distribution from the UPS output down to the rack.
- Packaged power distribution units
- Floor mount PDUs and cabinets
- Remote power panels
- Switchboard and panelboards
Transformers
Dry-type transformers specified against the harmonic profile of the real load, not the nameplate.
- Harmonic mitigating transformers
- Ultra-efficient transformers (CSL3, CSL3 Plus, CSL4)
- Medium voltage power transformers
- Low voltage high efficiency transformers
Precision Cooling & Thermal Management
Computer room cooling that holds tight tolerances continuously, rather than comfort cooling asked to do a job it was not built for.
- In-row cooling
- Small-medium up/down flow
- Large up/down flow
- Ceiling suspended
Racks & Containment
Enclosures and aisle containment that make cooling work as designed instead of fighting itself.
- Server racks 42U-48U
- Small closet racks 24U
- Open frame and wall racks
- Hot and cold aisle containment
Surge Protection
Cascaded surge protection at the service entrance and at the critical panels downstream.
- High risk service entrance protection
- Cascaded and critical panel protection
- Signal and data line transient protection
- Surge disconnect switches
Power Quality & Energy Metering
Revenue-grade metering and waveform capture — the measurement that settles arguments about power quality.
- Advanced power quality meters
- Switchboard power metering
- Multi-circuit submetering
- Wireless circuit energy monitoring
Power Factor Correction
Dynamic correction and harmonic filtering — one of the few electrical upgrades with a payback an accountant recognizes.
- Dynamic power factor correction
- Capacitor banks
- Harmonic filtering
- Arc flash relay systems
Emergency Lighting Inverters
Centralized emergency lighting power — code-compliant egress lighting without a battery pack in every fixture.
- Centralized emergency lighting inverters
- Single and three phase configurations
- Code-compliant egress lighting power
- Self-testing and monitoring
Integrated Solutions
Pre-engineered power, cooling and rack in one enclosure — a data room delivered rather than assembled.
- SmartCloset (3-5 kVA)
- SmartCabinet (3.5-7 kVA)
- SmartRow 2 (up to 10 racks, 36 kW)
- SmartMod container modules
Switchgear, Panelboards & Subpanels
Distribution gear from the service entrance down to the subpanel, specified as part of the protection scheme rather than as a commodity.
- Low voltage switchgear and switchboards
- Medium voltage switchgear
- Gas-insulated switchgear — 145kV, 252kV and 363kV
- Panelboards and subpanels
