Expert Power Control 8291-1

21-fold switched AC/DC PDU to control and protect AV and IT equipment

Expert Power Control 8291-1 is a Power Distribution Unit (PDU) which allows switching and current measurement of electrical devices via a TCP/IP network or serial connection. Up to 21 AV and ICT devices can be connected to the unit. The special feature: Thanks to the integrated quality power supply unit, typical AC or DC consumers with different voltages and connection types can be supplied, measured and controlled: PCs, servers, monitors, amplifiers, routers, NAS, external drives etc.

Expert Power Control 8291-1 disposes of the following switchable outlet connectors on the rear panel:

                 4x IEC C13 (230V AC)     
                 3x 4x terminal clamp (12V/24V DC configurable)  
                 5x terminal clamp or 5x USB A (5V DC)                                   


Further benefit: Due to the integrated industrial power supply unit in Expert Power Control 8291-1, the space-consuming plug-in power supply units of the connected consumers can be discarded.


The load outputs can each be switched separately via a web interface, via the serial interface, via SNMP or the button on the AC/DC power switch. Safety is a top priority: Each DC output is protected with its own eFuse, so that short circuits in connected devices do not affect other consumers. Furthermore, a type 3 overvoltage protection is integrated and prevents damage to the device and connected consumers.

Expert Power Control 8291-1 supports SNMPv3, SSL and IPv6 as well as Telnet, Radius and Modbus TCP. The measurement of a wide range of electrical parameters enables the user to identify and exploit power saving potentials in the IT environment. In addition, responsibles receives warning messages when fault currents occur (residual current measurement type A). This enables preventive maintenance measures to be taken before downtime occurs. 

Applications
• Switching network or media technology devices through media controls of well-known AV manufacturers (Atlona, ​​Barco, Crestron, Extron, Neets)
• Restart PCs, servers, routers, and switches remotely
• Reduce power consumption of standby devices through schedule control
• Network monitoring through integration with monitoring software (PRTG, Icinga, Nagios, Power IQ, Tivoli)
• Switch and control servers and IT equipment in server rooms and data centers
• Environmental monitoring by connected sensors (temperature, humidity and air pressure)

Locations
• AV environments: huddle rooms, conference rooms, theaters, auditoriums, LED walls or digital signage systems
• IT installations: Engineering rooms, data centers, 19 "cabinets or server rooms
• Industrial environments: Production facilities, warehouses or workshops
