Acrel ADL Power Meter (RS485 Modbus/RTU)

Acrel ADL Series is a reliable lineup of Power Meters for Industrial use. It can measure the standard Voltage, Current, and Power consumption. ADL Power Meters can measure either Single-Phase or Three-Phase voltage depending on the models. They also come with RS485 Modbus/RTU Protocol so that you can communicate and pass the data to any kind of monitoring system for your applications. All of the models in the series meet the related technical requirements of electricity meters in the IEC62053-21 IEC61000 and EN50470 standards. The available Acrel ADL Series are:

• ADL200 Single Phase Power
• ADL200N Single-Phase Power Meter with CT-Clamp
• ADL400 Three-Phase Power Meter
• ADL400N Three-Phase Power Meter with CT-Clamp

Note: CT-Clamp included with ADL200N and ADL400N have its own specifications different from the power meter itself. The power meters can measure up to 300A, but the CT-Clamp included can only measure up to 80A. You need to use a proper CT-Clamp that suits your rated current usage. 

LCD Display

Acrel ADL Series Power Meter comes with an 8 or 12-digit LCD Display (Depending on the model) that can display up to 23 useful information for your use. You can easily use the buttons to change the display to show the information that you want, one at a time.

Wiring

You can wire the Acrel ADL Series Power Meter in many configurations to suit your system and application. Please refer to the manual and instructions for the respective models for further details on operating the power meter.

DIN Rail Compatible

All Acrel ADL Series Power Meters are compatible with DIN Rail (DIN Rail is not included). This makes it really suitable for industrial use because of its compatibility with industrial environments and factories.

Applications

Acrel ADL400 3-Phase Power Meter can used in either standard consumer houses or even industrial-grade factories.
