Multi-load power analyzer for single or three-phase systems installable on DIN rails. Manages current input via one or two groups of split-core current sensors connected with RJ-11 connectors. The ET272 is equipped with RS485 ports for daisy chain connections.

Benefits

• Reduced installation time and errors. Equipped with detachable terminals for all connections. Connected to two groups of split-core current sensors with two cables fitted with RJ-11 connectors. For connections in cascade of multiple ET272s the voltage reference is required only once.

• Installation flexibility. It can be installed in new or existing single- and three-phase systems. Suitable for DIN rail mounting .

• Granular analysis. It provides single-phase or threephase measurements (up to 2 three-phase loads or up to 6 single-phase loads).

• Tamper-proof. The terminals and display can be sealed.

• Self detection of primary current of the TCDxM (the dedicated current transformers).

• Easy identification. The labels supplied with the instrument guarantee a quick identification and the subsequent commissioning (powered by VMU-C).

• Quick installation. The ET272s automatic addressing (via VMU-C) and configuration guarantee a quick installation. In a Data Center with server racks using power bus-bar trunking system, costly commissioning time can be reduced up to 94%.

Features

• Up to 2 three-phase loads or 6 single-phase loads managed simultaneously.

• Up to 400 A input current via pre-cabled groups of current sensors (TCDxM) or any primary current of current up to 10000 A sensor with 0.333 V secondary output (via connection adapter TCDMM).

• Single-phase or three-phase measurements: V, A, W/VA/var, kWh, kvarh, PF.

• Accuracy: better than a combination of a class 1 meter and a class 0.5 current transformer.

• Easy connection function.

• Up to 80 ET272 connected to a VMU-C

• Additional RS485 port for chain connection.

• Self power supply via voltage inputs.

• Detachable terminals and sealable terminal caps.
