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 EM140PURS meter is an electrical measuring device operating on a single-phase network with RS485 Modbus communication and two pulse outputs. It has been designed so that all the parameters of the electricity network can be read directly on the meter and the information fed back to a BMS. This direct-connection meter meters up to 40 A.

This product is also available in a MID version.

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, current, active and reactive 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 40 A meter is only 17.5 mm wide, i.e. 1 module.

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.
