Expert PDU Energy 8301 Series

Metered PDU for TCP/IP networks for vertical rack mounting

Expert PDU Energy 8301 Series enables metering of electrical appliances through TCP/IP network. The device disposes of three power supplies (one power supply for 8301-2) and three load outlets (one load outlet for 8301-2). It is available in three different amperage options. There are two energy meters integrated for each phase. The sensor interface allows monitoring of ambient temperature and humidity by optional available sensors.
