Energy / Power Quality Meters

Product Brochure Energy costs are becoming a significant expense in most processes. With increased energy unit costs, decreased generating capacity, and the environmental concerns with the burning of fossil fuels, it is important that companies reduce their electrical consumption.

Carlo Gavazzi offers a broad range of energy meters and power quality meters and transducers for monitoring energy consumption as well as problems with power quality.

In addition, with the move towards renewable energy, monitoring of photo-voltaic strings is becoming important in order to maximize generating capacity. The Gavazzi EOS Array system allows you to monitor the current, voltage, power, temperature, and irradiation levels of your entire solar installation.

In order to interface with external systems, output options include:

Relays
Analog
RS232
RS485
Ethernet (Modbus and BacNet)

In addition to the broad range of energy meters and power quality meters, Carlo Gavazzi also offers a number of software products for monitoring of a network of meters and transducers. This allows at-a-glance viewing of your complete power system.

Frequently Asked Questions

What is the EM21 energy meter?

The EM21 is a three-phase energy meter, listed on this page as a three-in-one energy monitoring device. The same unit, with a removable front LCD display, can be used for DIN-rail or panel mounting. It is suitable for active and reactive energy metering for cost allocation and for measuring and retransmitting the main electrical parameters, with a pulse output for active energy as standard and a 2-wire RS485 port as an option.

What communication protocols do Carlo Gavazzi energy meters support?

To interface with external systems, output options include relays, analog, RS232, RS485, and Ethernet (Modbus and BACnet). Carlo Gavazzi also offers software products for monitoring a network of meters and transducers, for at-a-glance viewing of your complete power system.

Can Carlo Gavazzi monitor a solar installation?

Yes. The Gavazzi EOS Array photovoltaic monitoring system monitors the current, voltage, power, temperature, and irradiation levels of an entire solar installation. This page also lists the EOS Array Lite, the EOS Box, and a solar irradiation sensor.
