• Supports Radius- und Modbus TCP protocol

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)

• Metering of differential current type A (mA)

• 1 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

• 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

• Support for the 802.1X standard for port authentication in the network

• Encrypted communication through SSL (TLS 1.1, 1.2, 1.3) and SSH

• Password protected access
