It includes simple indicators and integrated surge protection, making it a solid pick for small to mid-size network racks where a compact, straightforward distribution setup is needed. Best for: quick deployment in mobile or mixed-use racks. Limitation: fewer outlets than larger 1U PDUs, so plan outlet needs accordingly.
TRIPP LITE 12-Outlet 1U PDU
The Tripp Lite 12-outlet power strip is a robust 1U option with six front and six rear outlets, supporting a wide range of devices in IT closets and server rooms. It includes a long 15-foot cord and a locking-on/off switch for added security. The unit’s heavy-duty metal housing contributes to durability in demanding environments. Best for: racks needing several front-and-rear outlets with reliable circuit protection. Limitation: no USB ports embedded, so USB devices must use separate power sources.
UltraPoE 10-Outlet 1U PDU
The UltraPoE 1U PDU provides ten outlets with individual switches for granular power management. It supports 100-240V input and includes 1800 joules of overload protection for equipment safety. The 6-foot cord offers flexible placement within a rack. This option is best for IT environments that require easy outlet-by-outlet control and a higher level of protection. Limitation to consider: individual switch operation may require additional planning for startup sequencing in complex racks.
Tecmojo 1U 8-Outlet Horizontal PDU
The Tecmojo 1U 8-outlet horizontal PDU focuses on efficient distribution with 12A capacity across eight NEMA 5-15R ports. It includes LED indicators for power, earth, and surge protection to help monitor the power status of a rack. Best for: compact server racks needing clear status indicators and reliable surge protection. Limitation: fewer outlets than larger PDUs; plan for device density accordingly.
Buying Guide
Key considerations when selecting a 1U PDU include outlet count, mounting orientation, protection features, and what to plug in.
– Outlet configuration: Choose a mix of front and rear outlets to accommodate equipment with rear-facing power bricks and front-facing devices like USB peripherals.
– Protection and indicators: Surge protection, circuit breakers, and visual indicators help prevent damage and simplify troubleshooting in busy racks.
– Cord length and mounting: A longer power cord improves placement flexibility; horizontal vs. vertical mounting affects cable management and rack space.
– Individual outlets vs. shared controls: Some PDUs offer on/off switches per outlet; others provide a single master switch. Decide based on the need to power-cycle specific devices without affecting others.
– USB charging: If you rely on USB-powered devices, ensure the unit provides sufficient USB ports and power.
– Durability: Metal housings in IT-grade PDUs support longer life in demanding environments.
– Budget and density: Higher outlet density can save rack space but may come at higher cost. Plan based on current needs and anticipated growth.
