StarTech 12-Outlet Metered PDU
The StarTech 12-Outlet Horizontal Rack Mount Metered PDU provides 12 NEMA 5-15R outlets and a 125V/15A rating. It includes a built-in 8-foot power cord and a 1U footprint ideal for 19″ racks in data centers and labs. A large-display meter shows voltage, current, wattage, and power factor in real time, with an optional backlight for dim environments. The self-tripping MOV-based surge protector offers immediate protection against surges, and a resettable 15A circuit breaker with a safety cover helps prevent accidental power cycling. This unit supports reliable, centralized power management for multi-device racks.
TRIPP LITE Metered PDU, 15A, 13 Outlets
This Tripp Lite Metered PDU offers 13 outlets at 120V with a 15A circuit limit and a 5-15P input plug. It’s designed for rack enclosures and closets, delivering metered power distribution suitable for UPS or generator-assisted environments. A switch-free design reduces accidental shutdown risk, ensuring continuous operation for critical gear. The metering display provides current load readings to help prevent overload and optimize energy use in collaborative data rooms and labs.
StarTech 8-Outlet Metered PDU, 1U
The StarTech 8-outlet unit is a compact 1U PDU designed for 19″ rack deployments. It mirrors the larger model’s metering capabilities, with a large-font, optionally backlit display showing voltage, current, wattage, and power factor. A built-in surge protector with a resettable 15A breaker and safety cover provides layered protection for sensitive equipment like servers and network gear. The 8-foot power cord ensures flexible placement within the rack. This option balances footprint with essential metering and protection features.
30 Amp Metered PDU, 8 Outlets
This 30A metered PDU uses an aluminum shell and 8 outlets (C13) with 6 ft cord for high-current environments, including server rooms and crypto mining setups. The unit features a voltage/current display for real-time monitoring and an anti-electric shock module to enhance safety. The higher amperage capacity makes it suitable for workloads that draw significant power, while maintaining visibility into load and consumption. It is compatible with 120–240V systems using a L6-30P input plug and supports preventative overload management.
Tripp Lite Metered PDU with Isobar Surge
This PDU from Tripp Lite integrates Isobar surge suppression with metered power distribution. It is a 1U rack-mount unit featuring a digital current meter and robust EMI/RFI filtering to minimize electrical noise. With 14 total outlets, it supports mixed equipment configurations often found in data centers and labs. Isobar protection provides network-grade surge defense for critical servers, switches, and other rack-mounted devices while the metering readout helps operators avoid overloading the circuit.
Metered PDU 19 Inch, 7 Outlets
This BTU 7-outlet 19″ rack-mount PDU combines metering with an OLED display that shows real-time voltage and current. It includes surge protection and a 6-foot cord for rack flexibility. The compact 1U form factor fits standard enclosures while allowing space between outlets for larger power adapters. The display aids in live monitoring to prevent overloads and to manage energy costs across data closets and labs that rely on steady power delivery.
Buying Guide
- Metering accuracy: Look for clear readouts (voltage, current, wattage, power factor) and optional backlighting for dim environments. Higher accuracy helps prevent overloads and improves energy management.
- Outlet layout and type: Ensure the unit supplies the correct outlet types (C13/C14, C19, or NEMA 5-15R) for your equipment. Consider spacing between outlets for bulky plugs.
- Current rating and cord length: Select a PDU that matches the total load and the distance from the power source. A longer cord offers deployment flexibility, but confirm it doesn’t introduce voltage drop risks.
- Surge protection and safety features: Isobar or MOV-based protection adds resilience against surges. A resettable breaker and a safety cover reduce unintended power loss and user hazards.
- Rack footprint: 1U PDUs save rack space, but ensure the depth and mounting hardware fit your enclosure. For dense racks, a compact 8-outlet or 12-outlet model can balance power distribution and accessibility.
- Environmental considerations: In mining or lab environments, higher current capacity and robust enclosures (aluminum shells) can improve durability and safety in hot or dusty conditions.
- Warranty and support: Check the warranty period and whether the vendor offers service agreements or replacement policies, especially for mission-critical rack deployments.
When comparing options, prioritize metering precision, compatibility with your rack system, and built-in protections. For multi-device racks, a higher-outlet, higher-amperage PDU with Isobar or MOV surge protection can improve reliability, while smaller 1U models suit compact enclosures with modest loads. Consider both current load and anticipated growth to choose a unit that remains effective over time.
