GÜDE Expert Power Control 8291-2 21-Port Switched AC/DC PDU, 1U Rackmount, Ethernet, Metered

Take command of power distribution with the GüDE Expert Power Control 8291-2, a 21-port switched AC/DC PDU engineered for dense IT environments. This 1U rackmount unit delivers individual outlet control over 9 AC outputs (8x IEC C13, 1x IEC C19) and 12 DC outputs (4x 5V, 4x 12V, 4x 24V), enabling precise remote management of servers, network gear, and auxiliary devices. A built-in LED display provides at-a-glance monitoring of total current and IP address, while advanced metering captures current, voltage, power factor, active power, frequency, and energy for AC circuits, plus current and voltage for DC rails.

Advantages

This PDU stands out with its hybrid AC/DC design, allowing you to power both standard IT equipment and low-voltage DC devices from a single rack unit. Individual switching per outlet reduces downtime by enabling remote reboots without physical access. The integrated watchdog function automatically restarts unresponsive equipment, while configurable power-up delays prevent inrush current overloads during recovery. Robust security features—SSL, SSH, RADIUS, and user management—protect your power infrastructure from unauthorized access. Two sensor inputs support external environmental monitoring for temperature, humidity, or airflow, adding another layer of proactive management.

Suitable for

• Data centers and server rooms requiring granular outlet control and metering
• Remote sites and branch offices needing reliable power cycling and monitoring
• Industrial applications where mixed AC and DC equipment must be managed centrally
• IT administrators seeking to automate power scheduling and reduce energy waste

Recommendations

For maximum efficiency, integrate this PDU with your existing SNMP or Modbus monitoring system to centralize power data. Use the scheduling feature to shut down non-critical loads during off-hours, and connect environmental sensors to trigger automated responses. Ensure proper airflow in the rack to maintain operating temperature limits.
