Buying Guide: Key Considerations For Half-Rack And 1U PDUs
- Rack compatibility: Confirm unit height (U) and depth to fit your cabinet. Half-rack vs. 1U variants affect available space and device clearance.
- Outlet count and layout: Choose based on the number of devices and whether you need front or rear access. Consider outlets with individual switches for granular control.
- Protection features: Look for surge protection ( joules rating) and RFI/EMI filtering if sensitive equipment is used.
- Power rating and voltage: Ensure the unit matches your supply voltage (120V vs. 230V regions) and total current draw (amps).
- Cable management: Check cord length, included mounting hardware, and whether the unit allows neat routing within the rack.
- Installation options: Some models provide multiple mounting angles or front/rear switch access for flexible installation.
- USB charging and auxiliary ports: If you power USB devices, units with USB-A ports can reduce wall-wart adapters.
