21-fold switched AC/DC PDU


Additional information


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)
  • 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
  • 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)
