Description

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

The EMDCPURS meter is an energy meter operating on a DC network with Modbus RS485 communication and a pulse output. All the parameters of the electrical network can be read directly on the meter or sent to a BMS. This meter can be used up to 2000 A via a 60 mV shunt.

One product, several communications

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

Easy to use, the Modbus parameters are programmable on the front panel.

1 =

A multi-measurement meter

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

As well as energy, the meter also displays voltage and current.

2 =

Reduced footprint

Aware that space is a key factor in the design of your electrical panels, we have developed a compact range. Our DC meter is only 36 mm wide, equivalent to 2 modules.
