Definition
Smart DIN rail electricity meters are Prepayment energy meters which are fully compliant with IEC standards and used to measure unidirectional AC active and reactive energy with frequency of 50Hz/60Hz for residential, industrial and commercial customers.
It offers reliable performance and versatile functionality, with integrated communication modules supporting uplink connection with data concentrator (DCU) for energy data collection by 2G or PLC technology.
Main features
Energy Measurement
- The meter supports unidirectional measurement for active energy, reactive energy by using 2 measurement elements
- Shunt element on phase line
- CT on neutral line

Status Indicators (LED)-CIU
- Tampering Indicator: Indicate the tampering events.
- Credit indicator: Not lit up means Balance Credit ≥ Alarm Credit 1;
1. Yellow means Balance Credit ≥ Alarm Credit 2 and Balance Credit ≤ Alarm Credit 1；
2. Red means Balance Credit
- ≥Alarm Credit 3 and Balance Credit ≤ Alarm Credit2；
- 3. Red blinking when Balance Credit≤ Alarm Credit3.
- Com indicator: Indicate the communication statue. lit means CIU is in communication, blinking means communication out time.
