GUDE 8221-1 2x 6-Fold Switched & Metered PDU
GS-82211
The GUDE Expert Power Control 8221-1 is a 19-inch, 1U PDU designed to provide operational security and energy efficiency in IT and AV installations. It features dual banks of 6 switched power ports each, allowing independent control and metering for up to 12 devices. The unit supports proactive power and environment monitoring, helping detect potential issues early, while also enabling controlled switching to reduce energy consumption, electricity costs, and CO₂ emissions. Its dual-circuit design allows pairwise switching of power ports and connection to different phases. Plug-and-play sensors can be connected for temperature, humidity, and air pressure monitoring, reducing risks of physical hazards.
Features & Benefits
- Event and schedule controlled switching
- Total switching power: 7500 W
- Precise current metering of up to 9 units
- 2 connectors for plug-and-play sensors
- Fast and easy installation
- NTP function can be activated
- Integrated overvoltage protection type 3
- 2 independent banks of 6 power ports each (dual-circuit)
- Each power port can be switched via HTTP(S), SNMP, ModbusTCP or command line interface via Telnet, SSH, MQTT and serial interface
- Programmable on/off sequences for remote reboots (Remote Reboot)
- Self-healing function thanks to 12-channel watchdog: The power ports can be assigned its own Watchdog (ICMP/TCP), which initiates an automatic restart if necessary
- Pairwise switching of power ports possible, e.g., power port 1 of bank 1 simultaneously with power port 1 of bank 2
- 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
- Power consumption metering (kWh) with 2 energy counters: one counter counts consistently, the other counter is resettable
- Metering of current (A), voltage (V), phase angle, power factor, frequency (Hz), active power (W), apparent power (VA) and reactive power (VAr)
- 2 connectors for combined plug-and-play sensors (temperature, humidity and air pressure) to prevent often occurring physical hazards like overheating and increased humidity or air pressure
- Integrated type 3 overvoltage protection prevents damage to the device and connected loads
- Long-life High-Inrush Relays prevent welding of relay contacts during inrush current peaks
- 2 independent mains connections at 230 V for the same or different phases
- Generation of status messages and alarms (e-mail, syslog, SNMP traps, MQTT, SSH, Telnet)
- Encrypted e-mails (SSL, STARTTLS)
- Access protection by IP access control
- Encrypted communication through SSL (TLS 1.1, 1.2, 1.3) and SSH
- Password protected access
- Beeper for audible alarm when sensor limits are exceeded/deceeded
- Per bank an 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
