Expert Power Control 8042

12-fold switched PDU with GSM connectivity to increase operational reliability in IT networks

Expert Power Control 8042 Series enables switching and metering of electrical appliances through TCP/IP network, serial interface or mobile device app. Thanks to GSM connectivity, it is also possible to control and monitor the connected consumers out-of-band, i.e. via a redundant communication channel. The Series consists of two versions with 12 load outlets on the rear panel:

     8042-1: 12x IEC C13         8042-2: 12x IEC C13 Lock     

The Power Ports are individually switchable through web interface, serial interface, SNMP or a button directly on the device. Moreover SNMPv3, SSL, IPv6, Telnet, Radius and Modbus TCP support are incorporated. The integrated GSM module enables control and alarming via SMS, voice call and datacall. An alarm center can be informed by an SMS trap. The Expert Power Control 8042 disposes of energy and residual current measurement type A. The latter enables preventive maintenance measures to be taken thanks to automatic warning messages in case of residual currents.

• Switch and control servers and IT equipment in server rooms and data centers
• Guaranteed device control by redundant communication via GSM network
• 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)
• Environmental monitoring by connected sensors (temperature, humidity and air pressure)

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