Product Overview
The GUDE Expert Power Control series offers compact, intelligent Power Distribution Units (PDUs) designed to optimize space and enhance control in AV, IT, and digital signage installations.
The main visual depicts a modern, clean desk setup in an office or media environment. A large monitor is positioned centrally. To the left, behind the monitor, the compact GUDE Expert Power Control 1121-1 unit is discreetly mounted. To the right, underneath the desk, the slightly larger GUDE Expert Power Control 1141-1 unit is installed. This illustration emphasizes the space-saving and integrated nature of these PDUs in professional installations.
Expert Power Control 1141-1
This robust IP power distributor features 4 power ports and integrated current measurement. Its compact design allows for quick installation under tabletops and within media furniture.
Expert Power Control 1121-1
The small IP power solution provides 2 switchable load outputs, making it ideal for space-saving mounting behind displays and TVs.
Key Benefits:
- ▶️ Full Power Control: Power, control, and switch up to 4 AV devices individually, either onsite or remotely.
- ▶️ Seamless Software Integration: Easy and fast commissioning with free drivers for leading AV and IT control systems (e.g., Crestron, Extron, Domotz, Q-SYS).
- ▶️ Detailed Monitoring: Precise energy measurement and monitoring of temperature and humidity via plug-n-play sensors.
- ▶️ Enhanced AV Service: Remote reboots and automatic power cycling prevent costly downtime and improve service efficiency.
- ▶️ Reduced Costs & CO2 Emissions: Minimize power consumption and carbon footprint with programmable shutdown schedules.
- ▶️ Flexible Mounting: Compact designs enable space-saving installation behind displays, under tabletops, and within AV furniture.
- ▶️ Increased Operational Safety: Integrated overvoltage protection and proactive power monitoring ensure reliable and safe operation.

Technical Details & Features
Switching Function
- ⚙️ 2 or 4 load outputs individually switchable at the device via HTTP(S), SNMP, ModbusTCP, Telnet, SSH, and MQTT.
- ⚙️ Switching state and switch-on delay (0-9999 seconds) adjustable for each power port after power failure.
- ⚙️ Current peaks during simultaneous switching operations are prevented by an automatic latency of 1 second.
- ⚙️ Programmable schedules and on/off sequences.
- ⚙️ 2 or 4 channel watchdog (ICMP/TCP) assigned to each power port.
- ⚙️ Load outputs can be switched when preset sensor thresholds are exceeded.
Metering Function
- ? Connection for plug-n-play sensors for environmental monitoring (temperature, humidity, air pressure).
- ? Input-side measurement of current, voltage, phase angle, power factor, frequency, active, apparent, and reactive power.
- ? 2 energy meters: one meter counts permanently, the other is resettable.
Security
- ? Integrated overvoltage protection prevents damage to the device and connected consumers (L-N 10 kA), status retrievable over network.
- ? Long-life high-inrush relays prevent welding of relay contacts during inrush current peaks.
- ? Generation of status messages and alarms (e-mail, syslog, SNMP traps, MQTT, SSH, Telnet).
- ? Encrypted e-mails (SSL, STARTTLS).
- ? Access protection through IP access control.
- ? SNMPv1, v2c, v3 (Get/Traps) support.
- ? Encrypted communication via SSL (TLS 1.1, 1.2, 1.3) and SSH.
- ? Password protected access.
Operation
- ▶️ Easy and flexible configuration via web browser, Windows, or Linux program.
- ▶️ Firmware update possible during operation via Ethernet.
- ▶️ Support of Radius, Modbus TCP, and MQTT 3.1.1.
- ▶️ IPv6-ready.
- ▶️ Configuration and control via Telnet.
