Premium+ PDU with RackLink

The Middle Atlantic RLNK-P920R-SP is a Premium+ power distribution unit with integrated RackLink management. It provides nine outlets rated for 20 A service and series surge protection. The unit accepts an AC input range of 80-140 V. It is designed for installers and IT managers who need remote power control and detailed energy monitoring for rack-mounted equipment.

Thermals noise and power draw

The PDU delivers superior metering accuracy, reporting total power draw down to the outlet level with readings for current, voltage, power, power factor and energy usage. Multiple environmental sensors can be connected to monitor temperature and humidity, alerting staff to conditions that could threaten uptime. Firmware updates are applied remotely without shutting down the unit, maintaining continuous operation.

Behaviour under sustained load

Integrated scheduling supports variable timed sequencing, ping sequencing and auto-healing thresholds to keep systems stable during extended runs. Multiple notification options warn operators before limits are reached. Universal compatibility through custom drivers, SNMP v3/MIB, JSON-RPC and third-party integrations allows the PDU to be managed by existing control and IT platforms. A third-party Wi-Fi dongle can be added for wireless connectivity.

Questions about this item

How is the RLNK-P920R-SP mounted in a rack and which step is most often missed?

Mount the unit using its built-in rack ears, then secure the rear support brackets so the PDU cannot sag — that rear bracket step is the one installers skip.

Which consumable part on the RLNK-P920R-SP will need replacement after repeated surge events?

The internal surge-protection modules are sacrificial; after absorbing large transients they must be replaced to restore full 20 A series protection.

At what sustained load does the RLNK-P920R-SP hit its thermal limit first?

Continuous draw near the 20 A rating on the 80-140 V input will trip the internal thermal breaker before any other limit is reached.
