Key Features

General

Simple and quick mounting even in the smallest AV installation
Event and schedule controlled switching
Self-healing function
Precise current metering of up to 9 electrical units
Connector for plug-and-play sensors
Lightweight and robust plastic housing
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 2-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
Zero Voltage Switching (ZVS) avoids high switching currents by switching at the zero crossing of the AC voltage

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 surge protection (SPD) 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)
Support for the 802.1X standard for port authentication in the network
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
