Frequently Answers and Questions

What are the key features of this energy meter?

The energy meter offers multi-tariff management, absolute and average maximum demand calculation, tamper detection, and power failure management.

What type of microcontroller is used in this energy meter?

The energy meter is powered by the ST72F321 microcontroller.

What types of tamper detection are supported?

The energy meter can detect two types of tamper: box tamper and line/voltage wire tamper.

How does the energy meter communicate with a handheld unit (HHU)?

The energy meter supports IrDA communication compliant with IEC 62056 protocol Mode C, allowing for data reading and parameter changes via an HHU connected to a PC serial port.

What is the purpose of the EEPROM in this energy meter?

The EEPROM is used for storing sensitive data, such as energy readings, tamper information, and maximum demand data.

What is the role of the STPM14 ASSP in this energy meter?

The STPM14 metering ASSP is a key component that measures active energy, detects tamper events, and provides a pulse output proportional to the measured power.
