It uses a 125V/15A circuit with a built-in surge protector, a resettable 15A breaker, and a safety cover to guard against accidental resets. This model is ideal for data centers and server rooms requiring robust visibility across a larger rack deployment.
StarTech.com 8-Outlet Horizontal Metered PDU
This 8-outlet, 1U rack-mount metered PDU from StarTech.com offers a real-time power display for monitoring voltage, current, wattage, and power factor. It includes a surge protection mechanism with a resettable circuit breaker and a safety cover, making it a solid pick for compact rack environments needing reliable load visibility and protection.
Buying Guide: Key Purchase Considerations
- Power rating and outlets: Match the PDU’s amperage and the total connected load to your equipment. More outlets are helpful for dense racks, but ensure the unit can handle the aggregate draw without overheating.
- Voltage range and compatibility: Choose PDUs compatible with your facility’s voltage (110–120V vs. 208–240V environments). Cryptocurrency rigs and high-density servers often push higher loads; verify a 15A or higher circuit capacity as needed.
- Metering features: OLED or LED displays, real-time metrics (voltage, current, watts, PF), and data logging support capacity planning and proactive management. Consider backlit displays for low-light data centers.
- Surge protection and protection mechanisms: Surge protection helps shield equipment from transient spikes. Look for self-tripping breakers and robust MOV-based protection for reliability in server rooms.
- Form factor and mounting: 1U rack-mount PDUs save space, but ensure compatibility with your enclosure’s depth and mounting rails. Front-facing outlets can simplify cabling in tight racks.
- Durability and environment: Metal chassis and rack-mount design are essential for data centers and mining ops. Consider thermal considerations and ventilation in cabinets with multiple high-draw devices.
- Management needs: If you manage many racks, consider PDUs with network-enabled monitoring or compatible management software for centralized oversight and alerting.
- Safety and compliance: Ensure products meet local electrical codes and sustainability standards. For crypto mining or intense workloads, verify rating stability under prolonged high-load conditions.
When selecting a metered PDU, balance price against reliability, display clarity, and the ability to scale with your rack deployments. The five options above emphasize real-time monitoring, solid protection, and rack-ready form factors suitable for small-to-medium data centers, server rooms, and crypto-ready environments.
