Description

Installed upstream of an electrical circuit, energy meters are used to identify and monitor an electrical consumption network.

Our wide range of products can be used for metering and measuring directly connected single-phase, three-phase or four-phase circuits of up to 100 A and up to 6000 A when connected via current transformers.

The EM35TCPURS meter is an electrical measuring device operating on a tri-phase and four-phase network with RS485 Modbus communication and two pulse outputs. It has been designed to be able to read all the electrical parameters on the meter display. the Modbus communication allow also to monitoring all the electrical parameters on a PLC or BMS.

This current transformer (CT)-connected meter provides metering from 5 to 6000 A.

This product is also available in a MID version.

The same product for every type of communication

The EM35TCPUPURS is fitted as standard with two pulse outputs and RTU Modbus communication.

1 =

A multi-measurement meter

Our range of Modbus RS485 communicating meters can undertake a complete analysis of your network.

As well as active energy, the meter also displays voltage, intensity, active, reactive and apparent power, power factor and frequency.

2 =

Compact products

Aware that space is a key factor in the design of your cabinets, we have developed a compact range. Our CT meter is only 72 mm wide, i.e. 4 modular width.

3 =

Secure meter

Our meters are supplied with terminal covers to prevent any risk of electric shock. These terminal covers can also be sealed to prevent fraud.

4 =

Easy wiring of existing installations

The BACS (Building Automation and Control System) requires all commercial buildings to be fitted with a BMS if they have a heating or air-conditioning system of more than 70 kW.

Our range of open CT or Rogowski loop meters makes it easy to add metering points to your electrical installation with minimum downtime. There’s no need to de-cable the existing installation, just wrap the cable around the CT or loop.

What’s more, our network expert can offer you a support service for uploading information to a web page.
