Technical Details

1. Measurement of key electrical parameters: current (A), voltage (V), phase angle, power factor, frequency (Hz), active power (W), apparent power (VA) and reactive power (VAr)
2. Encrypted communication through SSL (TLS 1.1, 1.2, 1.3) and SSH
3. LxWxH: 87 x 4.4 x 4.4 cm (without mounting brackets)
4. Weight: approx. 2.5 kg
5. Length of mains cable: 3 m
6. Operating temperature: 0-50 °C
7. Storage temperature: -20 – 70 °C
8. Relative humidity: 0 – 95 % (non condensing)

Electrical Connections

1. 1 power supply safety socket type F (max. 16 A, 230 V)
2. 4 power ports IEC C19 (max. 16 A) and 16 outlet ports IEC C13 (max. 10 A) for 8311-15, 8311-16
3. 1 Ethernet connector RJ45 (10/100 Mbit/s)
4. 1 sensor connector (RJ45) for plug-and-play sensors

Metering function

1. Power consumption metering (kwH) with 2 energy counters: one counter counts consistently, the other counter is resettable
2. Metering of current (A), voltage (V), phase angle, power factor, frequency (Hz), active power (W), apparent power (VA) and reactive power (VAr)
3. Metering of differential current type A (mA)
4. 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

1. Generation of status messages and alarms (e-mail, syslog, SNMP traps MQTT, SSH, Telnet)
2. Encrypted e-mails (SSL, STARTTLS)
3. Access protection by IP access control
4. Encrypted communication through SSL (TLS 1.1, 1.2, 1.3) and SSH
5. Password protected access
6. Beeper for audible alarm when sensor limits are exceeded/deceeded

Operation

1. Easy-to-read LED display for displaying total current, IP address and sensor values
2. Firmware update via Ethernet during operation (no restart required)
3. Simple and flexible configuration via web browser, Windows or Linux program
4. Dynamic assignment of an IP address via DHCP or manual assignment of static IP address
5. Rapid commissioning thanks to free and reliable drivers from our technology partners
