Pros & Cons
👍 Pros
- Dedicated 20A rating supports high-draw professional equipment bays without relying on a shared 15A consumer circuit.
- Nine outlets provide enough coverage for a fully populated single-bay rack without requiring a secondary PDU.
- Rackmount form factor integrates cleanly into standard 19" equipment racks, eliminating floor-level power strips.
- Surge protection adds a hardware-level barrier between your equipment and line transients.
- Middle Atlantic's professional-grade construction is a known quantity in broadcast and AV integration work.
👎 Cons
- No published joule rating for the surge protection module makes it difficult to compare suppression capability against competing PDUs.
- Lack of individual outlet switching means you cannot remotely cycle power to a single device — a limitation power users managing remote racks will feel immediately.
- A 20A inlet requires a 20A circuit and a NEMA 5-20 receptacle; facilities wired only for 15A will need electrical work before installation.
- No current metering or digital display means you are managing load distribution by calculation rather than real-time monitoring.
Frequently Asked Questions
What is the maximum load the PD-920R-SP can handle before tripping?
The unit is rated at 20A total capacity. At 120V that gives you 2,400W of headroom across all nine outlets — enough to run a full bay of network switches, patch panels, and signal processors, but you should plan your load so you stay under 80% (1,920W) for continuous operation to avoid nuisance tripping.
Does the surge protection on the PD-920R-SP offer any indication when it has been compromised?
The product description does not specify an MOV-failure indicator light. If surge protection status feedback is critical to your installation, verify this with the Middle Atlantic datasheet before purchase.
How many rack units does the PD-920R-SP occupy?
The PD-920R-SP is designed for standard rackmount installation, but the exact rack-unit height (1U vs. 2U) is not confirmed in the available specifications. Measure your available bay space and confirm with Middle Atlantic's published dimensions before ordering.
Is the PD-920R-SP suitable for use in broadcast or AV touring racks subject to vibration?
Middle Atlantic builds its PDUs for fixed professional installations — server rooms, AV control rooms, and broadcast racks — rather than touring applications. For road cases subject to significant vibration, check whether the outlet retaining mechanism meets your requirements.
Can I daisy-chain two PD-920R-SP units to expand outlet count?
No. Daisy-chaining PDUs on a single 20A circuit would not increase available amperage and creates a shared-load scenario that could exceed the upstream breaker. Each PDU should be connected directly to its own 20A circuit.
