Expert PDU Energy 8311

7-/8-fold metered PDU with integrated current metering and monitoring for TCP/IP networks

Expert PDU Energy 8311 enables power distribution and metering of electrical appliances through TCP/IP network. There are two energy meters integrated. SNMPv3, SSL, IPv6 and Telnet, Radius and Modbus TCP support are incorporated. The meterd PDU is also available with residual current monitoring type A (RCM).

The Series consists of four versions with 7 or 8 load outlets on the front panel:

8311-1: 7x safety socket type F   8311-2: 7x safety socket type F, RCM    
: 8x IEC C13                     8311-4: 8x IEC C13, RCM

Expert PDU Energy 8311 disposes of two energy meters and allows measuring of various electrical dimensions. A clearly visible and lighted LCD display (two-line) provides all relevant device information. The sensor interface allows monitoring of ambient temperature, humidity and air pressure by plug-and-play available sensors.
