Expert Power Control 8291-1 for more operational security and energy efficiency in 19-inch installations

• Fewer and shorter failures of IT and AV installations
• Detect AV and IT problems at an early stage: Proactive power and environment monitoring
• Increased energy efficiency (Green IT and AV): Reduction of electricity costs and CO2 emissions
• Integrate anywhere: Quickly and easily integrate anywhere with API interface: REST API, https, SNMP, Telnet and MQTT
• Fix AV and IT problems quickly and effectively: Reboot remotely, directly on the device or with an automatic restart thanks to integrated watchdog

Key Features

• Event and schedule controlled switching
• Connection of AC and DC consumers with different voltages and connection types
• Precise current metering of up to 9 units and residual current
• 2 connectors for plug-and-play sensors
• Fast and easy installation
• NTP function can be activated
• Integrated overvoltage protection type 3
• Each DC output is fused via an eFuse

Switching function

• Each power port can be switched via HTTP/S, Telnet, SSH, SNMP or command line interface, as well as via serial interface
• 17 DC switchable power ports with 24 V, 12 V and 5 V (industrial clamp, USB a)
• 4 AC switchable power ports with 230 V (IEC C13)
• Programmable on/off sequences for remote reboots
• Power ports can be switched when preset sensor thresholds are exceeded
• Self-healing function thanks to 8-channel watchdog: The power ports can be assigned its own Watchdog (ICMP/TCP), which initiates an automatic restart if necessary
• Switching state and switch-on delay up to 9999 seconds (166 minutes) individually adjustable for each output port after power failure
• Current peaks due to increased inrush currents are automatically prevented by sequential switch-on with a latency of 1 second

Metering function

• Power consumption metering (kwH) with 2 energy counters: one counter counts consistently, the other counter is resettable
• Current metering for 5 V, 12 V and 24 V
• Maximum available DC current per port: 4 A
• Current distribution of the banks: 5 V (max. 8.8 A), 12 V (max. 6 A), 24 V (max. 12.5 A)
• Metering of current (A), voltage (V), phase angle, power factor, frequency (Hz), active power (W), apparent power (VA) and reactive power (VAr)
• Metering of differential current type A (mA)
• 2 connectors for combined plug-and-play sensors (temperature, humidity and air pressure)

Security

• Integrated type 3 overvoltage protection prevents damage to the device and connected loads (L-N, L/N-PE), status retrievable via network
• Each power port is protected against short circuits thanks to integrated eFuse
• Integrated industrial power supply (max. 300 W) with active harmonic filter (PFC)
• MTBF value of the power supply unit: Approx. 1.8 million operating hours
• Long-life High-Inrush Relays prevent welding of relay contacts during inrush current peaks
• Generation of status messages (e-mail, syslog and SNMP traps)
• Encrypted e-mails (SSL, STARTTLS)
• Access protection by IP access control
• Encrypted communication through SSH
• Secure Login via SSL
• Beeper for audible alarm when sensor limits are exceeded/deceeded

Operation

• Easy-to-read LED display for displaying total current, IP address and sensor values
• Firmware update via Ethernet during operation (no restart required)
• Simple and flexible configuration via web browser, Windows or Linux program
• Dynamic assignment of an IP address via DHCP or manual assignment of static IP address
• Convenient control on the go via free GUDE Control+ app (Android and iOS)
