The Carlo Gavazzi EM24 Energy Analyser delivers comprehensive three-phase electrical power monitoring, certified metering accuracy, and flexible communication telemetry engineered specifically for industrial motor control centers, building automation networks, commercial sub-metering panels, and renewable solar energy systems.

Advanced Power and Energy Management with the Carlo Gavazzi EM24 Energy Analyser

Designed to consolidate power analysis within high-density switchboards, the Carlo Gavazzi EM24 Energy Analyser captures real-time electrical performance across single-phase, two-phase, and three-phase power distribution circuits. The instrument records true RMS variables—including phase-to-neutral voltages, phase-to-phase voltages, line currents, active power (kW), reactive power (kvar), apparent power (kVA), grid frequency, and individual phase power factors—enabling accurate electrical tracking across variable and non-linear process loads.

The analyser is engineered for simple on-site deployment, featuring a distinctive front micro-joystick that allows commissioning technicians to configure current transformer (CT) and potential transformer (PT) ratios, address settings, and measurement pages rapidly. Available in direct-connection versions up to 65 A as well as standard 5 A CT-operated configurations, the meter supports bidirectional energy counting to track both imported and exported active kilowatt-hours for distributed solar generation and net-metering facilities.

For facility-wide supervisory integration and energy management accounting, the device incorporates an optically isolated RS485 serial communication interface supporting standard Modbus RTU protocol. In addition to digital fieldbus telemetry, the EM24 provides digital pulse outputs and auxiliary digital inputs, supporting dual-tariff energy tracking, remote breaker status monitoring, and direct coupling to facility SCADA systems.

Frequently Asked Questions

What is the purpose of the joystick on the Carlo Gavazzi EM24 Energy Analyser?
The integrated front micro-joystick allows technicians to navigate menus, select displayed electrical parameters, and configure system settings directly on the device without having to connect external programming tools or software interfaces.

Can the meter differentiate between power consumed and power fed back into the grid?
Yes. The Carlo Gavazzi EM24 Energy Analyser features bidirectional energy registers that record forward (imported) and reverse (exported) active energy independently, making it suitable for renewable solar PV arrays and grid feed-in monitoring.

How are the digital inputs used in energy management applications?
On models equipped with digital inputs, the terminals can be wired to utility signals to switch between tariff rates (e.g., peak vs. off-peak energy billing) or configured to count external pulses from water and gas sub-meters.
