The Power & Cooling category covers the physical infrastructure that keeps compute hardware energized and within operating temperature: uninterruptible power supplies (UPS) ranging from single-rack tower units to three-phase modular systems, power distribution units (PDUs) with metered, monitored, and switched outlet options, in-row and precision air-cooling units, computer room air conditioners (CRACs), rear-door heat exchangers, and associated busway, transfer switches, and battery cabinets. Products span capacities from sub-1 kVA desktop UPS to 500 kW utility-scale power modules, covering both 120 V single-phase and 208/480 V three-phase environments.

Datacenter operators, colocation tenants, edge-deployment teams, and HPC/AI cluster builders rely on this equipment to maintain uptime SLAs and protect sensitive GPU and server hardware from power events and thermal excursions. Key buying considerations include IT load in kW, rack density (kW per rack), desired runtime at full load, redundancy topology (N, N+1, 2N), cooling delivery method (air versus liquid), and management interface requirements such as SNMP, Modbus, or vendor-specific DCIM integration.
