Key Features
General
Event and schedule controlled switching
Precise current metering of up to 9 electrical units and residual current
2 connectors for plug-and-play sensors
Simple and quick mounting due to integrated mounting straps
NTP function can be activated
Integrated overvoltage protection type 3
Robust plastic housing
Switching Function
Each power port can be switched via HTTP(S), SNMP, ModbusTCP, Telnet, SSH, MQTT and serial interface
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 8-channel watchdog (ICMP/TCP)
Switching state and switch-on delay up to 9999 seconds (166 minutes)
Sequential switch-on with a latency of 1 second prevents current peaks
Zero Voltage Switching (ZVS)
Metering Function
Power consumption metering (kWh) with 2 energy counters
Metering of current, voltage, power factor, frequency, active power, apparent power and reactive power
Metering of differential current type A (mA) and type B (mA)
2 connectors for combined plug-and-play sensors (temperature, humidity, air pressure)
Security
Integrated type 3 overvoltage protection
Long-life High-Inrush Relays prevent welding of relay contacts
