Distribution, visibility, and control are different jobs.
A PDU’s outlet count does not tell you whether it measures load, reports it over a network, or lets you switch individual outlets. Check those capabilities explicitly.
Compare the management tiers
| Category | Typical purpose | Verify separately |
|---|---|---|
| Basic | Distribute input power to multiple outputs | Electrical rating, connectors and protection |
| Local metered | Show load information on the unit | Which quantities are measured; no assumed networking |
| Network monitored | Report measurements remotely | Protocols, security, sensors, and measurement granularity |
| Switched | Control outlets or outlet groups | Control granularity and whether metering is included |
Terminology varies between manufacturers. Treat category names as a starting point and read the exact product’s capabilities. A switched product does not automatically have per-outlet power measurement.

The PDUMH15 example
Eaton’s PDUMH15 provides a local current meter, thirteen 5-15R outlets and a 12 A continuous rating at 120 V. It is not a remote power-cycling solution and does not contain battery backup. If either is required, change the product category.

What to write in your buying checklist
- Supply voltage, input connector and cord reach.
- Continuous rating for the exact regional model.
- Output connector types, count and physical arrangement.
- Mounting orientation, rack space and service clearance.
- Required measurements, remote protocols and switching granularity.
- Manufacturer-approved use with the intended UPS or supply.
