Description

Installed upstream of an electrical circuit, energy meters are used to identify and monitor an installation’s electricity consumption.

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 EM35TCPU meter is an electrical pulse meter operating on a 3 phase + N network. It has been designed to be able to read all the electrical parameters on the meter display or to monitoring all the electrical parameters on a PLC or BMS. This meter is connected to a current transformer (CT) and provides metering from 5 to 6000 A.

This product is also available with RS485 Modbus communication and in a MID version.

Compact products

Aware that space is a key factor in the design of your cabinets, we have developed a compact range. Our 40 A meter is only 17.5 mm wide, i.e. 1 module.

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.

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.
