Model 1141 - 4-Fold Switched and Metered PDU

Key Features

• Simple and quick mounting even in the smallest AV installation
• Event and schedule controlled switching
• Precise current metering of up to 9 electrical units and residual current
• Connector for plug-and-play sensors
• Self-healing function
• Hybrid surge protection (SPD type 3)

Switching function

• Each power port can be switched via HTTP(S), SNMP, ModbusTCP or command line interface via Telnet, SSH or MQTT
• Programmable on/off sequences for remote reboots (Remote Reboot)
• Power ports can be switched when preset sensor thresholds are exceeded
• Self-healing function thanks to 4-channel watchdog: Each power port can be assigned its own Watchdog (ICMP/TCP), which initiates a fully 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
• Metering of current (A), voltage (V), phase angle, power factor, frequency (Hz), active power (W), apparent power (VA) and reactive power (VAr)
• Connector 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

Security

• 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
• 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

Operation

• Easy-to-read LEDs displaying switching status of outlets and device status
• 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
• Rapid commissioning thanks to free and reliable drivers from our technology partners
