EM270 Multi-Channel Power Analyser

Multi-circuit power analyser for single or threephase systems installable on panels or DIN rails. Manages current input via two current transformer blocks connected with RJ-11 connectors.

The EM270 is equipped with a LCD display with controls to display measurements and configure the system, a RS485 port and two pulse outputs or two RS485 ports for daisy chain connections.

Benefits

Reduced installation time and errors. Equipped with detachable terminals for all connections, with possibility of requesting pre-wired cables (optional). Connected to two current transformer blocks with two cables fitted with RJ-11 connectors. For connections in cascade of multiple EM270s the voltage reference is required only once.

Installation flexibility. Suitable for panel or DIN rail mounting.

Granular analysis. It provides total measurements or single circuit measurements (up to 2 three-phase circuits or up to 6 single-phase circuits).

Specific software. The UCS proprietary configuration software enables rapid configuration and the display of all measurements. The software and subsequent updates are free.

Tamper-proof. Configuration access can be locked. The terminals and display can be sealed.

Self detection of primary current of the TCD (the dedicated current transformers).

Features

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

• Up to 630 A input current via solid-core current transformer blocks (TCDxX or TCD0W).

• Three installation configurations: on DIN rails, mounted on panel of 72 x 72 or 96 x 96 (with optional adapter).

• Single circuit measurements: V, A, W/VA/var, PF, kWh, kvarh. Virtual circuit (sum or difference) measurements: W/VA/ var, PF, kWh, kvarh.

• Display of electrical variables: 3 digits. Display of energy meters: 7 digits.

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

• Easy connection function.

• Up to 20 EM270 connected in cascade.

• RS485 port.

• Optional outputs: additional RS485 port for chain connection or two pulse outputs.

• Self power supply via voltage inputs.

• Detachable terminals and sealable terminal caps.

• Configuration via keypad or UCS configuration software.
