Energy Metering

This Product Selection Guide contains information to help select products in the Energy Metering category on DigiKey.com

Energy metering integrated circuits are designed for high-accuracy electrical energy measurement in single, dual, and three-phase power line systems. They measure line voltage and current and can calculate active, reactive, and apparent energy as well as instantaneous rms voltage and current.


SelectionCharacteristics

Input Impedance: Characterizes the impedance of a device’s analog signal inputs.

Measurement Error: Manufacturer’s advertised measurement accuracy.

Voltage - I/O High: Characterizes the upper range of voltage allowed on the device’s input/output pins while in a Logic High state.

Voltage - I/O Low: Characterizes the upper range of voltage allowed on the device’s input/output pins while in a Logic Low state.

Current - Supply: This represents the maximum current to which a device will meet its given specifications. Exceeding this current may damage the device and/or other system components.

Voltage - Supply: Typically represented by a range, this indicates the low and high voltage limits which one can expect standard operation. Voltages outside this range may damage the device and other system components.

Meter Type: Indicates whether a metering IC is designed for measurement of single-or polyphase electrical services.

Operating Temperature: Recommended operating temperature, typically given in a range or as a maximum. Exceeding these temperatures may affect performance or damage the device and other system components.

Mounting Type: Indicates how the device is attached.

Package / Case: Indicates the type of protective case used on an electronic component to allow easy handling, installation, and protection. This selection was determined to be the closest industry standard applicable to the suppliers device packaging. Typically it is best to check the actual dimensions from the datasheet rather than depend on this terminology when designing your circuit.

Supplier Device Package: This is what the manufacturer calls the package of this device. They are manufacturer specific. It is typically best to use the actual dimensions from the datasheets rather than to go by this terminology when designing your circuit.
